Abstract: A control valve includes a terminal assembly that has a terminal electrically connected to one of a male electrical connector and female electrical connector. A solenoid assembly includes a metallic solenoid housing defining a solenoid cavity. A solenoid coil and the other of the male electrical connector and the female electrical connector are molded into a plastic solenoid carrier. The plastic solenoid carrier is attached to the metallic solenoid housing and preferably molded into the solenoid cavity. The solenoid assembly is attached to the terminal assembly, and said male electrical connector is mated to the female electrical connector. An armature is positioned between a portion of the terminal assembly and the solenoid coil. A valve member is attached to the armature.

Abstract: The present solenoid stator assembly is adapted to be mounted upon a mounting seat of a fuel injector valve. The assembly includes a housing having an upper end, a lower end, and a base adapted to fit on the mounting seat of the fuel injector valve. A substantially E-shaped stator core is disposed within the housing. The stator core includes a top portion having a first end and a second end. A first outer pole piece depends substantially perpendicularly from the first end, and a second outer pole piece depends substantially perpendicularly from the second end. The central pole piece is located substantially central to the first and second outer pole pieces, and depends substantially perpendicularly from the top portion in a direction substantially parallel to that of the first and second outer pole pieces. The first and second outer pole pieces and the central pole piece each have a distal end forming a face, each face being substantially flush with the base of the housing.

Abstract: A fuel injector assembly and a control valve for such an assembly which automatically compensate for changes in the emissions generated by the engine by changing the timing of fuel injection within the engine. The fuel injector assembly, which causes fuel to be injected during a fuel injection cycle having a start time and a stop time, includes a fuel injector nozzle, a fuel pump, and a fuel inlet associated with the fuel pump, which causes fuel to be periodically pumped from the fuel inlet through the fuel injector nozzle. A control valve, which is associated with the fuel pump and which controls the start time and the stop time of the fuel injection cycle, includes a valve body and a solenoid-actuated armature disposed in a recess in the valve body. The armature has a first side and an opposed second side and is reciprocable within the recess between a first position and a second position.

Abstract: A standing valve assembly providing a large cross-sectional flow area to reduce flow restrictions while in a production mode. A preferred embodiment of the valve is capable of movement in a valve alignment guide from a normally biased open position. The normally biased open position provides a large flow area. When removal of accumulated fluid in a wellbore is required, gas-lift gas closes the valve to isolate the producing formation allowing the fluid to be lifted from the wellbore. After removal of the fluid is completed and the gas-lift is stopped, the valve returns to its normal open position to allow flow through the valve assembly.
