1. A linear compressor defining an axial direction, a radial direction and a circumferential direction, the liner compressor comprising:
a cylinder assembly having a sleeve, the sleeve having an inner surface and an outer surface spaced apart from each other along the radial direction, the outer surface of the sleeve defining a groove extending about the sleeve along the circumferential direction, the outer surface of the sleeve also defining a plurality of channels extending from the groove of the sleeve along the axial direction, the sleeve also defining a plurality of thru-holes, each thru-hole of the plurality of thru-holes positioned at a distal end of a respective one of the plurality of channels, each thru-hole of the plurality of thru-holes extending through the sleeve to the inner surface of the sleeve, the inner surface of the sleeve defining a chamber; a piston slidably received within the chamber of the sleeve, the piston having an outer surface that is positioned adjacent and faces the inner surface of the sleeve, the outer surface of the piston defining a plurality of pockets, each pocket of the plurality of pockets aligned with a respective one of the plurality of thru-holes of the sleeve; and a driving coil operable to move the piston within the chamber of the sleeve, wherein 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 sized for directing liquid oil therethrough during operation of the linear compressor. |
