Abstract (en)
[origin: DE19826339A1] Disclosed is a valve for controlling liquids. The inventive valve can be actuated by a piezo-actuator (53) which acts directly upon a valve member (40) pertaining to said control valve (31). A Peltier element (62) is inserted in the flow of heat from the piezo-actuator (53) to a heat dissipating part of the housing in order to compensate for various differences in length that arise as a result of temperature influences. The Peltier element (62) is controlled by an electric control device (36) in such a way that various temperature- induced differences in the length of the piezo-actuator (53) in relation to those of the housing (2) accommodating the piezo-actuator are at least partially compensated.
