Abstract:
Valve for regulating fluids, comprising:a piezo-electric actor unit (9) for operating a valve member assembly, said valve member assembly having a first piston (13) guided in a valve body (10) and a second piston (14), wherein a hydraulic chamber (16) acting as a hydraulic converter is disposed between said first and second pistons (13, 14), wherein the second piston operates a valve closing member (15) on an end of said second piston (14) facing away from the hydraulic chamber (16), wherein said valve closing member (15) cooperates with at least one valve seat (17) formed on the valve body (10) and in a closed position, said valve closing member (15) separates a system pressure region (18) from a high pressure region (5), wherein the second piston(14) in a direction of the hydraulic chamber (16) is surrounded by and supported by means of casing-type spacer (22) on the valve body (10).
