The fuel injector includes a solid state actuator that operates through an actuator motion amplifying lever to directly control the needle valve motion. Hydraulic forces, which act along the axes of the needle valve and the motion amplifying lever, are compensated by using a control piston, or other biasing means, to reduce the required amplitude of the control current/voltage and to reduce the required strength of the spring biasing the needle valve closed. The fuel injector may also include a control fuel inlet that is separate from the injection fuel inlet port.

A locking tab (46) is formed in the first side wall and includes a thumb notch (48) located within the tab. The top lid panel includes a pair of cover latches (28) located on the outer corners thereof. The bottom lid panel includes a pair of alignment tabs (40) located on the outer corners thereof. Each end wall includes a hand hole lock (60), a lock slot (64), and a recess (66) located along the end wall exterior edge. The lock slot is located between the recess and the hand hole lock. Each end wall further includes first and second reinforcing panel sub-assemblies (56), (58), each having an inner panel (70), (100), a middle panel (72), (102), and an outer panel (74), (104). Each inner panel includes a pair of recesses (82) and an intermediate tab (84) all located along an inner panel exterior edge. Each middle panel includes a locking slot (86) near the middle panel exterior edge. The outer panel (74) of the first sub-assembly includes a recess (78) along an outer panel exterior edge and a hand hole (80). As assembled, the locking tabs are disposed within the lock slots with the intermediate tab of the inner panel at least partially inserted into the locking tab thumb notch. The cover latches are inserted into the locking slots of the end walls. The alignment tabs are positioned in the aligned recesses of the outer panel and the end wall.
