Abstract
The present invention relates to a pressure control valve which includes a valve tappet that is guided in a valve housing and accommodates a compression spring, and a valve closure member which is shaped on the valve tappet and corresponds with a valve seat establishes a connection between a pressure supply conduit extending from a pressure fluid source and a pressure return line when the pressure reaches a defined preset nominal value. To reduce operating noises of the valve tappet, at least one polygonal friction element which engages with the valve tappet is movable into abutment on radial friction surfaces of the valve tappet.
