Abstract: A linear compressor includes a cylinder, a piston axially reciprocating in the cylinder, a first muffler unit coupled to the piston, a back cover that is disposed at a rear of the piston and defines an opening at a radially central area, and a second muffler unit coupled to the opening. The first muffler unit includes an inner guide disposed in the piston and a first intake muffler disposed at a rear of the inner guide. The second muffler unit includes a second intake muffler that communicates with the first intake muffler and is coupled to the opening, a muffler body surrounding the second intake muffler, and a muffler cover disposed between the muffler body and the back cover.

Abstract: A linear compressor includes a shell having a first opening and a second opening defined at opposite ends of the shell, a compressor body including a cylinder and a piston accommodated in the shell, a support part that protrudes from an end portion of the compressor body toward the second opening, a supporting damper that extends from the support part toward an inner surface of the shell. The supporting damper includes a first portion that is coupled to the support part and that defines a single contact region between the support part and the supporting damper, and at least two second portions that extend from the first portion to the inner surface of the shell and that define at least two contact regions that are spaced apart from each other along the inner surface of the shell.

Abstract: A linear compressor includes a shell, a motor in the shell, a mover coupled to the motor and configured to perform a reciprocating motion in an axial direction, a cylinder disposed in the shell, a piston coupled to the mover and configured to reciprocate in the cylinder, a spring that supports the piston in the axial direction, and a spring cap inserted into an end portion of the spring. The spring cap defines a space portion that is defined inside the spring cap and has a volume separate from the inner space of the shell, and a passage portion that extends through an axial side surface of the spring cap and is configured to provide communication between the space portion and the inner space of the shell.
