Abstract

The disclosure relates to a fluidically controlled pressure switching valve for a vehicle brake system including a valve chamber, which is arranged in a valve interior and into which an inlet opening and an outlet opening open, and a valve closing body, which is movable in the valve interior and which comprises a piston, defining a first piston surface and a second piston surface, and including a closing element. The valve closing body is movable in accordance with a pressure difference between a pressure acting on the first piston surface and a pressure acting on the second piston surface, against the force of a setting spring arranged in the valve interior, between a closed position, in which a fluid connection between the inlet opening and the outlet opening is interrupted, and an open position, in which the fluid connection between the inlet opening and the outlet opening is open.
