Abstract

The valve having a valve member guided displaceably in the direction of its longitudinal axis protrudes into a valve pressure chamber and has a sealing face extending transversely to axis, has a sealing face, which it cooperates with a valve seat, extending transversely to axis, for at least extensively closing off an opening, surrounded by the valve seat, from the valve pressure chamber. The sealing face is surrounded by an annular face, which when the valve member rests on the valve seat is disposed at a slight spacing from the valve seat. The valve member has a plurality of apertures, distributed over its circumference, through which the opening communicates with the valve pressure chamber when the valve member is resting on the valve seat.
