Abstract (en)

[origin: EP2136041A2] The valve has a piston which is arranged longitudinally within a bore, from whose inner wall (79) a pressure medium connection (P) and two working connections (A,B) come out. The piston has a pressure chamber-inlet channel (32) and a pressure chamber-outlet channel arranged separately from the inlet channel. The piston has a center slit, whose wall is connected to the pipe wall (80), such that the wall of the slit separates the pressure chamber-outlet channel from the pressure chamber-inlet channel.
