Abstract: A valve assembly 10 for use in a compressor. Valve assembly 10 includes a generally cylindrical stator member or assembly 12 and an inner valve or member 14 which is slidably engaged within stator assembly 12. Stator assembly 12 includes a conventional electrically operated coil 20 which is coupled to a conventional controller 98. Controller 98 selectively connects and disconnects coil 20 to and from a conventional battery 96, thereby allowing coil 20 to selectively receive electrical power. When coil 20 receives electrical power, a movable member 68 within member 14 is actuated, thereby creating a communication passage between a relatively high pressure chamber 84 and a relatively low pressure chamber 88.

Abstract: The present invention is a tool for inserting an evaporator orifice tube check valve into an evaporator orifice tube. The tool uses a press pin comprising a pneumatically activated cylinder which forces the evaporator orifice tube check valve into the evaporator orifice tube a predetermined distance. The tool also includes a reciprocating cylinder which locates the valve to a proper seating depth, a signal generator which notifies the operator if the valve in a particular evaporator is not seated properly, and a marking device which creates a label on the evaporator orifice tube only if the evaporator orifice tube check valve is at the predetermined desired location.
