연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

The invention relates to a device for controlling the filling and/or extraction of a fluid, for example, in relation to a pressurized fluid tank including a body having a connection end (516) which is equipped with engagement means that are intended to co-operate with complementary engagement means which are provided, for example, on a connection interface of a tank, a member (17) for opening a valve that can move in relation to the body, actuation means (250) which can move the opening member (17) selectively and which can move between a running position and a stopped position corresponding respectively to an operating position and a rest position of the opening member (17) and a hole (105) which can receive a removable outlet or inlet coupling (75) for the distribution of the fluid. The invention is characterized in that the device includes retractable locking means (55) which are used to lock the actuation means (250) in the running position and which are designed to co-operate with the hole (105), such that, when there is no coupling (75) connected to the control device in the corresponding hole, the locking means (55) are biased towards the retracted position, thereby preventing the actuation means (250) from being stably maintained in the running position.

1. A device for controlling the filling and/or the extraction of fluid from a tank of pressurized fluid comprising: (a) a body having a connection end provided with attachment means intended to collaborate with a tank connection interface,(b) a member for opening a valve that can move relative to the body,(c) actuating means capable selectively of moving the opening member, the actuating means being able to move between an on position and an off position which correspond respectively to a work position and a rest position of the opening member,(d) an orifice intended to accommodate a removable inlet or outlet coupling for distributing fluid, and(e) retractable means of locking the actuating means in the on position, the retractable locking means being configured in such a way as to collaborate with the orifice in such a way that when a coupling is not connected to the control device in the orifice, the locking means are urged into their retracted position preventing the actuating means from remaining stably in the on position,wherein the retractable locking means are configured in such a way that when a coupling is connected to the control device in the orifice, a lock activation element transmits a force to the locking means so as to maintain the latter in an active position that locks the actuating means in the on position andwherein the device further comprises intermediate means that transmit the maintaining force to the locking means; the intermediate transmission means comprising a moving member that has a first end capable of collaborating in abutment with a coupling in the orifice and a second end capable of collaborating in abutment with the retractable locking means. 2. The device of claim 1, wherein when a coupling is disconnected and extracted from the orifice, the maintaining force on the locking means is automatically removed, the locking means being retracted in order to switch the actuating means into the off position. 3. The device of claim 1, wherein the device further comprises return means urging the locking means toward the retracted position. 4. The device of claim 1, wherein the device further comprises a shut-off element capable of being moved between positions in which it opens and closes the orifice for the coupling, and in that the shut-off element constitutes the moving member of the intermediate means for transmitting the maintaining force to the locking means. 5. The device of claim 4, wherein the shut-off element comprises an attachment portion, when the shut-off element is in the opening position, the attachment portion projecting into the orifice so as to allow it to collaborate for the purposes of attachment with a mating portion belonging to a coupling. 6. A device for controlling the filling and/or the extraction of fluid from a tank of pressurized fluid comprising: (a) a body having a connection end provided with attachment means intended to collaborate with a tank connection interface,(b) a member for opening a valve that can move relative to the body,(c) actuating means capable selectively of moving the opening member, the actuating means being able to move between an on position and an off position which correspond respectively to a work position and a rest position of the opening member,(d) an orifice intended to accommodate a removable inlet or outlet coupling for distributing fluid, and(e) retractable means of locking the actuating means in the on position, the retractable locking means being configured in such a way as to collaborate with the orifice in such a way that when a coupling is not connected to the control device in the orifice, the locking means are urged into their retracted position preventing the actuating means from remaining stably in the on position and, wherein the actuating means comprise a translationally mobile switch. 7. A device for controlling the filling and/or the extraction of fluid from a tank of pressurized fluid comprising: (a) a body having a connection end provided with attachment means intended to collaborate with a tank connection interface,(b) a member for opening a valve that can move relative to the body,(c) actuating means capable selectively of moving the opening member, the actuating means being able to move between an on position and an off position which correspond respectively to a work position and a rest position of the opening member,(d) an orifice intended to accommodate a removable inlet or outlet coupling for distributing fluid, and(e) retractable means of locking the actuating means in the on position, the retractable locking means being configured in such a way as to collaborate with the orifice in such a way that when a coupling is not connected to the control device in the orifice, the locking means are urged into their retracted position preventing the actuating means from remaining stably in the on position, wherein the retractable locking means are configured in such a way that when a coupling is connected to the control device in the orifice, a lock activation element transmits a force to the locking means so as to maintain the latter in an active position that locks the actuating means in the on position and, wherein the locking means comprise an elastic attachment portion, the elastic attachment portion and the actuating means having mating shapes so that when the locking means are in the active locking position the movement of the actuating means toward the on position causes the elastic attachment portion to become attached to the actuating means. 8. A device for controlling the filling and/or the extraction of fluid from a tank of pressurized fluid comprising: (a) a body having a connection end provided with attachment means intended to collaborate with a tank connection interface,(b) a member for opening a valve that can move relative to the body,(c) actuating means capable selectively of moving the opening member, the actuating means being able to move between an on position and an off position which correspond respectively to a work position and a rest position of the opening member,(d) an orifice intended to accommodate a removable inlet or outlet coupling for distributing fluid, and(e) retractable means of locking the actuating means in the on position, the retractable locking means being configured in such a way as to collaborate with the orifice in such a way that when a coupling is not connected to the control device in the orifice, the locking means are urged into their retracted position preventing the actuating means from remaining stably in the on position, wherein the device further comprises closure means intended to make the member move into its rest position and wherein the closure means are able to move between an inactive position and an active position, in the active position, the closure means collaborating with the actuating means in order to move and/or to deform an elastic attachment portion and thus release the locking of the actuating means. 9. An assembly made up of a pressurized-fluid tank and a control device, the tank comprising a casing delimiting a storage volume and provided with an orifice allowing communication with the inside of the tank, a filling and distribution head positioned at the orifice, an isolating member such as an isolating valve, a connection interface intended to collaborate removably with a control device, wherein the control device is a device according to claim 1.
