연합인증

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

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

1. A fluid regulator, comprising: a fluid inlet;a fluid outlet;a first piston;a plurality of fluid passages including a first fluid passage and a second fluid passage;a first housing having a fluid connector configured to engage an output valve having a second housing;an actuator configured to, without utilizing an electrically powered component:open the output valve to provide a fluid flow path between the fluid inlet and the fluid outlet at least partly in response to: a first flow of fluid received via the fluid inlet that causes a first movement of the first piston that opens the first fluid passage, anda fluid flow through the fluid connector from the output valve second housing;the actuator further configured to, without utilizing an electrically powered component:close the output valve to obstruct the fluid flow path between the fluid inlet and fluid outlet at least partly in response to:an interruption of the first flow of fluid received via the fluid inlet,a subsequent, relative to the interruption of the first flow, second flow of fluid received via the fluid inlet, that causes a second movement of the first piston, andan interruption of the fluid flow through the fluid connector from the output valve second housing caused at least in part by a closure of the first fluid passage which is caused by the second movement of the first piston. 2. The fluid regulator as defined in claim 1, the fluid regulator further configured to: at least partly in response to the second movement of the first piston, transition the second fluid passage from a closed state to an open state. 3. The fluid regulator as defined in claim 1, wherein the fluid inlet comprises a plurality of fluid inlets, and the fluid outlet comprise a plurality of fluid outlets. 4. The fluid regulator as defined in claim 1, wherein the fluid connector of the first housing comprises a male threaded connector. 5. The fluid regulator as defined in claim 1, wherein the output valve having the second housing comprises a female threaded connector configured to threadedly engage the fluid connector of the first housing. 6. The fluid regulator as defined in claim 1, wherein the first fluid passage and the second fluid passage are fluidly connected via the fluid connector to a diaphragm port of the output valve. 7. The fluid regulator as defined in claim 1, the fluid regulator further configured to: maintain the first fluid passage in an open state during the interruption of the first flow of fluid. 8. The fluid regulator as defined in claim 1, wherein the fluid flow through the fluid connector from the output valve second housing comprises a gas or a liquid. 9. A fluid regulator, comprising: a fluid inlet;a fluid outlet;one or more pistons including a first piston;a plurality of fluid passages including a first fluid passage and a second fluid passage;a first housing having a fluid connector configured to engage an output valve having a second housing;an actuator configured to, without utilizing an electrically powered component:open the output valve to provide a fluid flow path between the fluid inlet and the fluid outlet at least partly in response to: a first pressure increase of a fluid flow received via the fluid inlet that equals or exceeds a first threshold, which causes a first movement of the first piston, which causes the first fluid passage to transition from a closed state to an opened state, anda fluid flow through the fluid connector from the output valve second housing;the actuator further configured to, without utilizing an electrically powered component: close the output valve to obstruct the fluid flow path at least partly in response to: a first pressure reduction of the fluid flow, received via the fluid inlet, that falls to or below a second threshold,a subsequent, relative to the first pressure reduction, second pressure increase of the fluid flow, received via the fluid inlet, that equals or exceeds the first threshold, that causes a second movement of the first piston, andan interruption of the fluid flow through the fluid connector from the output valve second housing caused at least in part by the closure of the first fluid passage, which is caused at least in part by the second movement of the first piston. 10. The fluid regulator as defined in claim 9, the fluid regulator further configured to open the second fluid passage at least partly in response to the second movement of the first piston. 11. The fluid regulator as defined in claim 9, wherein the first threshold and/or the second threshold are user configurable via a mechanical control of the fluid regulator. 12. The fluid regulator as defined in claim 9, wherein the fluid inlet comprises a plurality of fluid inlets, and the fluid outlet comprise a plurality of fluid outlets. 13.
