摘要：
The present disclosure is directed to a fuel injector. The fuel injector may include a casing substantially aligned along a central axis of the fuel injector. The fuel injector may also include a control valve configured to control a flow of fuel through the fuel injector. The fuel injector may also include a piezoelectric element disposed within the casing and associated with the control valve. The fuel injector may further include a motion coupler disposed between the control valve and the piezoelectric element the motion coupler configured to affect shock to reduce microscopic fractures within the piezoelectric element.
