Abstract
The present invention relates to a fuel supply device and a pressure control for a fuel supply device to supply fuel from a reservoir to a user, and a method for pressure control. The fuel supply device for a motor vehicle comprises a reservoir, which is emptied upon discharge via a pressure control of a control unit, with between an inlet side high-pressure chamber and an outlet side low-pressure chamber of the pressure control several flow paths are arranged, which are opened and closed and when they are flown through a pressure reduction occurs from the storage pressure of the reservoir to the operating pressure of the user.
Claims28
A fuel supply device (100) for a motor vehicle, comprising a reservoir (102), which is emptied upon discharge via a pressure control (107, 200, 300, 400, 500, 600, 800, 810, 820, 901, 911) of a control unit (106, 900, 910), characterized in that several flow paths (206a, 206b, 306, 306a, 406, 406a) are arranged between an inlet side high-pressure chamber (203, 303, 403, 501) and an outlet side low-pressure chamber (205, 305, 405, 502) of the pressure control (107, 200, 300, 400, 500, 600, 800, 810, 820, 901, 911), which are opened and closed and with them being flown through leading to a pressure reduction of the storage pressure of the reservoir (102) to the operating pressure of the user (101).
A pressure control (107, 200, 300, 400, 500, 600, 800, 810, 820, 901, 911), characterized in that at least two flow paths (206a, 206b, 306, 306a, 406, 406a) are arranged between a high-pressure chamber (203, 303, 403, 501) and a low-pressure chamber (205, 305, 405, 502).
A method to operate a pressure control (107, 200, 300, 400, 500, 600. 800, 810, 820, 901, 911) with several flow paths between an inlet side high-pressure chamber (203, 303, 403, 501) and an outlet side low-pressure chamber (205, 305, 405, 502), with a control opening the flow paths when the operating pressure is fallen short and closing the flow path when the operating pressure is exceeded.
