  • Patent number: 6273754
    Abstract: A hermetic compressor assembly including a housing; an electric motor disposed in the housing; a compression mechanism disposed in the housing and operatively coupled to the motor; a terminal assembly comprising a terminal body extending through and sealingly attached to the housing, at least one elongate conductor pin having interior and exterior ends, the interior pin end located inside the housing, the exterior pin end located outside the housing, and an insulator disposed between the pin and the terminal body, whereby the pin is electrically insulated from the terminal body by the insulator; a lead wire extending between the motor and the interior pin end, the lead wire having an electrical connection to the pin, the motor and the pin electrically connected by the lead wire, the lead wire having an insulative jacket; and an insulative covering which extends between the terminal body and the lead wire jacket, the insulative covering covering at least a portion of the terminal body, the insulator, the elect

  • Patent number: 6092284
    Abstract: A suction accumulator for a refrigerant compressor which is mounted to the compressor in such a way as to reduce the metal fatigue at the joint between the inlet tube and the suction accumulator, and reduce the potential for rust or oxidation of the metal of the suction accumulator. The suction accumulator includes a cylindrical housing with two domed ends, wherein an inlet tube extends into the inlet of the suction accumulator and is provided with a flared end. The flared end is attached to the inlet of the suction accumulator and the flared end matches the contour of the inlet such that when the two parts are joined they are congruent with each other to thereby reduce the vibration therebetween. The suction accumulator is also provided with an outlet which communicates refrigerant from the suction accumulator back to the compressor. The suction accumulator is secured to the outside wall of the compressor using a mounting bracket.

  • Patent number: 5252036
    Abstract: The present invention is a crankcase heater for preventing the migration of liquid refrigerant. The heater is located on the compressor housing surface near the oil sump. The heater is positioned within a fence of a terminal assembly, covering substantially all the surface area enclosed by the fence except for the terminal cluster itself. The heater provides heat to the housing and the interior of the compressor, and the gasket insulates the heater and interiorly reflects the heat produced. Liquid refrigerant in the oil sump is boiled off to increase the pressure inside the housing and inhibit migration of refrigerant from the evaporator or accumulator.
