Beschreibung
Zusammenfassung:	A fuel cut-off valve 51 having a valve housing 52 with a fluid inlet 53 and with a fluid outlet 54, wherein, in the valve housing 52, a fluid path 55 is formed between the inlet and the outlet, wherein a piston 56 is arranged in the fluid path, which piston divides the fluid path into an inlet-side fluid path section 57 and an outlet-side fluid path section 58, wherein the piston is biased against a sealing seat 60 by a force store 59, such that the fluidic connection between the inlet and the outlet is shut off, and wherein, in the event of a pressurization of the inlet-side and of the outlet-side, the piston lifts off from the sealing seat and opens up the fluidic connection between the inlet-side and the outlet-side, wherein, between the inlet-side fluid path section and the outlet-side fluid path section, there is provided a bypass duct 63 which can be closed off or opened up by an activatable valve 64. The piston and force-store may be configured to not lift off the seat when only the inlet-side is pressurized. The activatable valve in the bypass may be a solenoid valve. The valve may be used in a motor vehicle.
