Abstract
A linear compressor includes one spring assembly including a plurality of spring parts fixed to both side surfaces of a supporter and a rear cover and configured to support a load generated in the compressor. In addition, both side portions of the spring part are provided with fixing brackets coupled to the supporter and the rear cover, and the fixing bracket is provided with an insertion member or a bracket coupling member so that the coupling force of the spring part can be increased.
Claims20
A linear compressor comprising:
- a shell;
- a cylinder that is disposed in the shell and that extends in a frontward direction and a rearward direction, the cylinder defining a compression space therein configured to receive refrigerant;
- a piston disposed in the cylinder and configured to reciprocate in the frontward direction and the rearward direction;
- a supporter coupled to a rear end portion of the piston and configured to support the piston;
- a rear cover spaced apart from the supporter;
- and
- a spring assembly disposed between the supporter and the rear cover,
- wherein the spring assembly comprises:
- a plurality of spring parts, each of the plurality of spring parts having a first side portion that supports the supporter and a second side portion that supports the rear cover,
- a fixing bracket that defines a spring insertion portion configured to receive the first side portion of one of the plurality of spring parts or the second side portion of one of the plurality of spring parts, the fixing bracket being coupled to the supporter or the rear cover,
- wherein the rear cover comprises:
- a cover body having a plate shape,
- a plurality of bracket coupling portions that extend from the cover body in a radial direction and are coupled to the fixing bracket, the plurality of bracket coupling portions being arranged in a circumferential direction, and
- a cover recessed portion that is recessed from an outer circumferential surface of the cover body in the radial direction, the cover recessed portion being defined between the plurality of bracket coupling portions, and
- wherein the fixing bracket comprises:
- a bracket main body that is located on the cover recessed portion and that defines the spring insertion portion, and
- a body coupling portion disposed at each of both sides of the bracket main body.
