Abstract

Shut-off valve for a pressure accumulator vessel for a medium, wherein a valve housing has a valve chamber with an intake opening and an outlet opening facing the pressure accumulator vessel, a movable piston, and at least one spring, wherein the piston has at least one axial connecting channel and is guided in an axially movable manner by at least two sealing elements arranged in the valve chamber, wherein a first effective piston surface of the piston, the first effective piston surface facing an inlet region of the valve chamber, and a sealing body form a valve seat, and wherein, by changing the pressure in an accumulator region of the valve chamber, the accumulator region being adjacent to a second effective piston surface, the piston is axially movable and a passage opening arranged between the intake opening and the outlet opening may be reversibly closed and opened, wherein, in the unpressurized state, the passage opening is kept open by the spring.Pressure accumulator system for a vehicle, comprising at least one pressure accumulator vessel and at least one shut-off valve, which is operatively connected thereto.
