ABSTRACT:
A pressure control valve which serves to control a determined medium pressure. The pressure control valve includes a medium chamber with an inlet opening and an outlet opening for the medium to be controlled, separated by a membrane from a spring chamber with a valve spring. On the membrane, a valve member is floatingly disposed via a ball-shaped support member, which acts together with a valve seat. The outlet opening is disposed upstream of the valve seat in such a manner, that during a medium pressure to be controlled the valve member lies upstream of the outlet opening and together with the latter controls the flow of the medium to the valve seat, while during a medium pressure below the valve member descends with throttling action to a greater or lesser degree into the outlet opening and blocks the valve seat at a predetermined lower medium pressure.
