Abstract (en)

[origin: WO0114732A1] The invention relates to a valve for controlling liquids. The inventive valve is provided with a piezo actuator (5) and a hydraulic transmission device that transmits the lifting of the piezo actuator (5). The hydraulic transmission device comprises a pressure chamber (7) and a piston element (10) with a transmission surface (12). A valve member (18) that is connected to the piston element (10) can be actuated by means of the hydraulic transmission device. A mechanic transmission device is arranged between the hydraulic transmission device and the valve member (18).
