摘要

The pressure valve (1) has a bushing (2) having an axial piston bore (4), where a piston is arranged in the piston bore in axially movable manner. An inflow channel (8) is formed in the bushing coaxial to the piston bore, where the bushing has a valve seat surface (12) narrowing in direction to the inflow channel for a valve seat (14) with the piston. Outflow channels (10) are blocked against the inflow channel by the valve seat, where a control surface (22) expanding in direction towards the outflow channels is controlled on the valve seat surface.
