  • Method of making foam in an energy efficient compressor
    Patent number: 5499908
    Abstract: An energy efficient hermetic compressor for compressing hydrofluorocarbon refrigerants. The compressor includes a motor compressor unit with a rotating oil pickup tube to which an oil paddle is attached. The oil paddle rotates in a base lubricant of polyol ester mixed with a siloxane ester foaming agent. The combination of the foaming additive with the oil paddle creates a foam layer that floats in the oil sump to reduce the sound level of the compressor.

  • Suction muffler
    Patent number: 5496156
    Abstract: A hermetic compressor including a suction muffler disposed opposite the suction inlet tube. A funnelled or countersunk inlet port on the muffler permits semi-direct refrigerant flow into the muffler, creating enhanced cooling of the motor and higher compressor efficiency. Baffle walls disposed parallel and on opposite sides of an internal standpipe within the suction muffler create an increased resonator effect with optimum refrigerant throughput.
