Abstract
A pressure control for a fuel supply device to supply fuel from a reservoir to a user includes at least two flow paths between a high-pressure chamber and a low-pressure chamber, and an operable closure unit for opening and closing of the at least two flow paths.
Claims22
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;
- and
- an 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;
- and
- wherein 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.

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;
- and
- an 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;
- and
- wherein 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<L2<L3.
