Abstract

The valve has one or more pressure medium inlets and outlets, and a cylindrical chamber associated with the outlet. The chamber is limited at one end by a piston, and may be connected via a valve to the inlet. The valve housing and the piston wall form a seat valve. The first piston (7) is formed as a slide, between the medu inlet (4) and the seat valve (28,29,31). On the side away from the cylindrical chamber (6), and outside the medium outlet, the slide is guided sealed. The other end of the chamber is limited by a second piston (9), also guided sealed. This piston is connected to the first one via a piston rod (8). The active surfaces of both pistons, which limit the chamber, are similar.
