Abstract (en)
[origin: EP2249047A2] The hydraulic valve (1) has seat valves (3, 3') present parallel to a housing (2) that has two connections (A, B). The valves have control edges (6, 6') and piston-like valve bodies (5, 5') i.e. step pistons, supported opposite to one edge in the housing. A front side of one body cooperates with the edge to open or interrupt flow paths (14, 14'). A pressure chamber (10) of an actuation device (7) cooperates with the valve body for opening or interrupting the flow paths and for displacing the body with respect to the opening or interrupting of the flow paths.
