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.
