ABSTRACT:
The object of the invention is a force-controlled pressure regulating valve, wherein large flow areas can be opened in valves in a simple manner and likewise can be closed, using small operating forces and short setting paths. A valve member 2 is axially adjustable in a housing which is in permanent connection with a pressure medium inlet opening 8 and is blocked against a pressure medium output opening 18. Valve member 2 is configured as a hollow cylinder. Its one edge surrounds an opening leading to the output opening 18, and its other edge cooperates with a valve seat coaxial with a venting opening 20, and surrounds a second valve seat in the cover of valve member 2. A setting member 3 cooperates with this valve seat, which transmits the setting force for the valve member. This setting force counters a check force.
