  • Publication number: 20150226203
    Abstract: A linear compressor and a method for lubricating a piston in the same are provided. The linear compressor includes a sleeve that defines a groove, a plurality of channels and a plurality of thru-holes. A piston is slidably received within a chamber of the sleeve. The piston defines a plurality of pockets. The groove of the sleeve, the plurality of channels of the sleeve, the plurality of thru-holes of the sleeve, and the plurality of pockets of the piston are configured for directing liquid oil therethrough during operation of the linear compressor.

  • Patent number: 9086062
    Abstract: A linear compressor is provided. The linear compressor includes a casing that defines a chamber and a piston slidably received within the chamber of the casing. A driving coil is configured for selectively urging the piston to slide within the chamber of the casing. An electro-magnetic spring is configured for urging the piston towards a default position when the piston is positioned away from the default position. The electro-magnetic spring can permit the linear compressor to operate at a resonant condition.

  • Patent number: 8714946
    Abstract: A linear compressor is provided. The linear compressor includes an electro-magnetic spring and a casing that defines a chamber. A piston is received within the chamber of the casing. The electro-magnetic spring can apply a non-linear force to the piston such that a total spring force applied to the piston during a compression stroke is substantially linear.

  • Patent number: 6896499
    Abstract: Scroll compressors include a tap for communicating a compressed refrigerant to a back pressure chamber to resist a separating force. A restriction is placed within this tap to slow build-up of the back pressure chamber at start-up. Further, the restriction smoothes out any fluctuations in the back pressure force as the pressure in the compression chamber from which the refrigerant is tapped may fluctuate.
