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 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 pressure control, comprising: at least two concentrically arranged flow paths between a first chamber and a second chamber, the flow paths comprising a first flow path and a second flow path; andan operable closure unit for opening and closing of the at least two flow paths;wherein the operable closure unit comprises a magnetic anchor, an actuator, and a closure body;wherein the magnetic anchor is configured and located to open the first flow path by being lifted off an upper sealing surface of the closure body and to close the first flow path;wherein the closure body is configured and located to open and close the second flow path;wherein the actuator engages with the magnetic anchor and the closure body;wherein the magnetic anchor is actuated via a solenoid actuator;wherein the at least two flow paths are closed while the operable closure unit is not actuated;wherein the first flow path is opened by actuating the operable closure unit, wherein actuating the operable closure unit moves the magnetic anchor to thereby open the first flow path; andwherein the second flow path is opened, while the first flow path remains open, by increasing the actuation of the operable closure unit, wherein increasing the actuation of the operable closure unit moves the magnetic anchor further, wherein moving the magnetic anchor further moves the closure body via the actuator to thereby open the second flow path. 2. The pressure control according to claim 1, wherein the individual flow paths comprise identical cross-sections. 3. The pressure control according to claim 1, wherein the individual flow paths are opened or closed independent from each other. 4. The pressure control according to claim 1, wherein the individual flow paths are not opened or closed independent from each other. 5. The pressure control according to claim 1, wherein the flow paths are disposed in a joint housing. 6. The pressure control according to claim 1, wherein the flow paths are not disposed in a joint housing. 7. The pressure control according to claim 1, wherein one or more of the flow paths are disposed in a device to open or close the flow paths. 8. A method to operate the pressure control according to claim 1, wherein the first chamber is an inlet side first chamber and the second chamber is an outlet side second chamber, the method comprising opening the flow paths when an operating pressure is below a first threshold and closing the flow paths when the operating pressure is above a second threshold. 9. The pressure control according to claim 1, wherein the operable closure unit is disposed at a first side towards the first chamber for changing a position of the closure unit. 10. The pressure control according to claim 1, wherein the operable closure unit is disposed at a second side towards the second chamber for changing a position of the closure unit. 11. The pressure control of claim 1, wherein the flow paths are provided in parallel such that each of the at least two flow paths individually fluidly communicates the first chamber to the second chamber when the respective flow path is open. 12. The pressure control according to claim 1, wherein the operable closure unit comprises at least one member of the group consisting of: a mechanical device, a magnetic device, an electrical device, a pneumatic device, a hydraulic device, and combinations thereof. 13. The pressure control according to claim 1, wherein the first flow path has a first cross-sectional area and the second flow path has a second, larger cross-sectional area. 14. The pressure control according to claim 13, wherein the first flow path is opened or closed above a certain threshold pressure or below a certain threshold flow volume. 15. The pressure control according to claim 13, wherein the second flow path is opened or closed below a certain threshold pressure. 16. A fuel supply device for a motor vehicle, comprising: a control unit comprising the pressure control according to claim 1, wherein the first chamber is an inlet side first chamber and wherein the second chamber is an outlet side second chamber; anda reservoir, wherein the reservoir is emptied upon discharge via the pressure control;wherein a flow through the flow paths leads to a pressure reduction of a storage pressure of the reservoir to an operating pressure of a user. 17. The fuel supply device according to claim 16, wherein the control unit further comprises at least one member of the group consisting of: a sensor, a safety device, a thermal safety device, a side system shut-off valve, a filter element, an attached control device, and a heat exchanger. 18. The fuel supply device according to claim 16, wherein the control unit is used for at least one of discharge and refueling, the fuel supply device further comprising at least one member of group consisting of: line connectors for refueling to connect to a refueling coupling and the reservoir, anda return valve disposed at the inlet side. 19. The fuel supply device according to claim 16, further comprising a refueling coupling which is integrated in the control unit. 20. The fuel supply device according to claim 16, wherein the pressure control or the control unit is integrated in the reservoir. 21. The fuel supply device according to claim 16, wherein the control unit is addressed by an electronic control device, wherein the electronic control device controls the operating pressure of the user according to at least one member of the group consisting of: specifications of the user, and the storage pressure. 22. A pressure control, comprising: a first flow path connecting a first chamber to a second chamber;a second flow path connecting the first chamber to the second chamber in parallel to the first flow path such that each of the first and second flow paths individually fluidly communicates the first chamber to the second chamber; andan operable closure unit configured to open and close the flow paths, wherein the operable closure unit comprises an actuator, a magnetic anchor and a closure body;wherein the magnetic anchor is arranged to open the first flow path by being lifted off an upper sealing surface of the closure body and to close the first flow path;wherein the closure body is arranged to open and close the second flow path;wherein the actuator engages with the magnetic anchor and the closure body;wherein the magnetic anchor is actuated via a solenoid actuator;wherein actuating the magnetic anchor to engage the actuator to a first level L1 causes the operable closure unit to close the first and the second flow paths to fluidly isolate the first chamber from the second chamber;wherein actuating the magnetic anchor to engage the actuator to a second level L2 actuates the operable closure unit to open the first flow path while the second flow path remains closed, to provide fluid communication between the first chamber and the second chamber through the first flow path, wherein actuating the magnetic anchor to engage the actuator to the second level L2 moves the magnetic anchor; andwherein actuating the magnetic anchor to engage the actuator to a third level L3 actuates the operable closure unit to open the first flow path and the second flow path, to provide fluid communication between the first chamber and the second chamber through the first flow path and through the second flow path, wherein actuating the magnetic anchor to engage the actuator to the third level L3 moves the magnetic anchor further, wherein moving the magnetic anchor further moves the closure body, via the actuator;wherein L1
