Abstract: A linear compressor is provided that may include a shell having a cylindrical shape, a frame fixed inside the shell, a cylinder inserted to pass through the frame, a piston provided in the cylinder, a motor that linearly reciprocates the piston, and a stator cover coupled to the motor. The stator cover may include a cover body and a reinforcement sleeve bent from an outer edge of the cover body, the reinforcement sleeve having a plurality of protrusions that protrudes in a radial direction from the reinforcement sleeve. A portion of the shell corresponding to a position of each of the plurality of protrusions includes a bulge that protrudes in the radial direction of the shell.

Abstract: A linear compressor includes: a shell; a cylinder provided inside the shell; a frame coupled to an outer side of the cylinder; a piston configured to reciprocate in an axial direction; a motor that supplies power to the piston; and a spring mechanism coupled to the piston. The spring mechanism includes: a support connected to the piston and including a spring support unit having one or more insertion holes; a first coupling protrusion that extends from the rear side of the spring support unit along the edge of the insertion hole; a support cap inserted into the insertion hole and including a second coupling protrusion protruding from the front side of the spring support unit; a first resonant spring inserted into the outer circumferential surface of the second coupling protrusion; and a second resonant spring inserted into the outer circumferential surface of the first coupling protrusion.

Abstract: A linear compressor includes a hole that is defined in a discharge cover, and is configured such that a portion of a refrigerant discharged through an opened discharge valve is guided to flow to the hole. Accordingly, a discharge passage for the refrigerant used as a gas bearing may be easily defined.
