  • Motor-driven reciprocating piston compressor, particularly for hermetically encapsulated small refrigerators
    Patent number: 4427346
    Abstract: The invention relates to a motor driven reciprocating piston compressor of the type utilized for encapsulated small refrigerators. Valving for the valve plate between the piston and cylinder chamber provides automatic unloading when the gas in the cylinder chamber falls below a predetermined temperature in the 80 to 100 degree centigrade range to prevent pressure build ups in the cylinder chamber during idle periods which cause undesired high starting torques.
