Abstract

A linear compressor includes a linear motor including a mover that reciprocates with respect to a stator; a compression unit configured to define a compression space in a cylinder while a piston connected to the mover reciprocates in the cylinder; a frame disposed outside of the cylinder; a plurality of discharge covers that define discharge spaces sequentially receiving refrigerant discharged from the compression space; and a gas bearing configured to guide part of refrigerant accommodated in a discharge any one of the plurality of discharge covers to lubricate between the cylinder and the piston with the refrigerant. The discharge cover structure is configured to restrict heat transfer between the discharge covers and the frame.
