Abstract

A valve assembly for a hydraulic discharge device and including a piston displaceable in a bore of a housing of the discharge device against a biasing force and having an outer surface, which sealingly engages an inner wall of the housing bore and blocks a channel opening into the bore so that the piston functions as a slide valve for this channel, the valve assembly further including a valve seat which, together with the piston, forms a seated valve.
