Abstract: A linear compressor includes a casing, a back cover supported in the casing, an intake flow path member coupled to the back cover, and an intake muffler of which at least a portion linearly reciprocates inside the intake flow path member. The intake flow path member includes a first hole that is formed in a front surface and is penetrated by the intake muffler, and a flow path guide that extends axially forward from a rear surface and has an opened front and an opened rear. A noise of a refrigerant passing through the intake flow path member can be reduced through an expansion space between the flow path guide and an inner surface of the intake flow path member.
