ELEMENT FOR THE TRANSMISSION OF A MOVEMENT AND INJECTION VALVE PROVIDED WITH SUCH AN ELEMENT
According to the invention, a clearance compensating transmission element (3) is provided between the piezo actuator (2) and the valve element (5) of a servo valve for an injection valve. Said transmission element (3) comprises a drive piston (31) and a receiving element (32) which engage in a telescopic manner and encompass a chamber (322) containing a hydraulic medium. The gap between the drive piston (31) and the receiving element (32) is dimensioned in such a way that a short-time increase in the pressure in said chamber (322) is not equalised out; longer lasting pressure differences, however, are reduced.
