| 摘要 |
The current invention relates to a valve for controlling fluids, which includes a piezoelectric actuator (2), a transmission mechanism for increasing the stroke of the piezoelectric actuator (2), and a control valve (14) that can be actuated by means of the transmission mechanism. In addition a temperature compensation device (27) is provided to compensate for a length change of the piezoelectric actuator (2) induced by a temperature change. The transmission mechanism is embodied in the form of a diaphragm (3) and increases the stroke of the piezoelectric actuator with a transmission ratio a/b. At the same time, the diaphragm (3) produces a seal between the piezoelectric actuator (2) and the fluid to be controlled.
