Abstract
A linear compressor includes a cylinder, a frame, and a discharge unit. The discharge unit includes a discharge cover coupled with the frame, a discharge plenum disposed inside the discharge cover to define a plurality of discharge spaces, and an insulating plenum provided in a shape corresponding to an inner surface of the discharge cover to contact the inner surface of the discharge cover.
Claims19
A linear compressor comprising:
- a cylinder that defines a compression space for compressing refrigerant;
- a frame that receives the cylinder;
- and
- a discharge assembly that defines a discharge space for discharging the refrigerant, wherein the discharge space receives the refrigerant from the compression space,
- wherein the discharge assembly includes:
- a discharge cover connected to the frame;
- a discharge plenum disposed on the discharge cover and defining the discharge space;
- and
- an insulating plenum having a shape that corresponds to at least part of an inner surface of the discharge cover and contacts the at least part of the inner surface of the discharge cover,
- wherein the insulating plenum includes a bearing guide groove, and
- wherein the refrigerant flows through the bearing guide groove to the frame between the insulating plenum and the discharge cover.
