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.

Abstract: The present invention relates to an electromagnetic valve for a tank valve of a fuel supply system of a gas fuel motor vehicle, comprising a magnetic coil with an inner guide, and a magnetic armature which can move axially in the inner guide. The magnetic anchor consists of an anchor, a seal element which is arranged between the anchor and a fuel inlet, and a counter pole which abuts the seal element. The present invention also relates to such a tank valve and to a fuel supply system having such an electromagnetic valve.

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.
