Valve for controlling fluids |
摘要 |
A valve for controlling fluids in which the valve is actuatable by a piezoelectric actuator that acts directly on a valve member of the control valve. To compensate for changes in length of different magnitudes resulting from temperature factors, a Peltier element is incorporated into the heat flow from the piezoelectric actuator to a heat-dissipating part of the housing, and the Peltier element is triggered by an electric control unit in such a way that temperature-dictated changes in length of the piezoelectric actuator are at least partly compensated for compared with those of the housing receiving the piezoelectric actuator.
