A pressure regulating valve has a valve chamber with a supply for connection to a pressure source. It also has a valve member which is placed on a seat surface in a valve body by a closing spring with an adjusting pressing force. A throttle opening is provided in the valve body to a return conduit. The pressure regulating valve is formed so that the valve member releases the throttle opening to the return conduit in correspondence with a load condition of an internal combustion engine, depending on its stroke path.
