摘要： A valve assembly is disclosed. The valve assembly has a housing having a first recess disposed on an interior surface of the housing and at least one valve-supporting element disposed within the housing. The valve assembly also has a washer disposed within the housing, the washer having a first washer surface and a projection for transferring torque. The first washer surface abuts against a first valve-supporting element surface of the at least one valve-supporting element and the projection is received in the first recess. The valve assembly also has a first fastener disposed within the housing and having a first fastener surface abutting against a second washer surface of the washer.

摘要： A common rail fuel injector includes a needle valve member that moves to open and close nozzle outlets for a fuel injection event responsive to pressure in a needle control chamber. Between injection events, the needle control chamber is fluidly connected to the fuel inlet by a first pathway that includes a Z orifice, and fluidly connected to the fuel inlet by a second pathway that includes an F orifice, an intermediate chamber and an A orifice. During an injection event, the needle control chamber is fluidly connected to a drain outlet by a third pathway that includes the A orifice, the intermediate chamber and an E orifice. Different performance characteristics are achieved by adjusting the sizes of the respective of F, A, Z and E orifices.

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.
