发明名称 Piezoelectric control valve adjustment method
摘要 A method for adjusting piezoelectric valve components to create a precise interface between a piezoelectric actuator and a movable valve plunger is provided which includes the steps of conducting a coarse adjustment prior to assembly followed by a fine adjustment after assembly. The method includes measuring a first difference between a valve body and a valve plunger, and compensating for this first measured difference such that surfaces of the valve body and the valve plunger are in a common plane. A second common plane is established between an end surface of an actuator housing and an end of an actuator rod. The step of compensating for the first measured difference can comprise machining the surfaces in the first common plane or using a shim. A second adjustment is conducted by rotating a nut disposed axially with the actuator rod to adjust the axial position of the valve plunger.
