PRESSURE-REDUCING VALVE

A pressure reducing valve with a valve housing, with a valve carrier in the housing interior having a throughflow channel, and with a cup-shaped valve body displaceably guided from an open position into a closed position counter to a restoring force, where the valve body abuts a valve seat on the valve carrier formed as a sealing ring, closing a channel opening. The sealing ring is held in an annular groove of the valve carrier and is axially supported by the groove flanks. The groove flank which faces the valve body ends in front of the inner circumference thereof, which abuts the sealing ring when the pressure reducing valve is closed. A sealing-lip-like circumferential molded-on formation is molded on that end face of the sealing ring which faces the valve body, and this formation moves against the inner circumference of the valve body when the primary pressure on the inlet side of the valve rises.
