Abstract: A linear compressor includes a discharge valve detachably attached to a front end surface of a cylinder to open and close a compression space of the cylinder; and a valve spring elastically supporting a rear surface of the discharge valve to press the discharge valve toward the front end surface of the cylinder. The discharge valve includes reinforced fiber, and the reinforced fiber is arranged parallel to the front end surface of the cylinder. Accordingly, while a rigidity of the discharge valve is improved, a weight of the valve is reduced to enhance responsiveness of the valve, suppress abrasion of the cylinder, and reduce striking sound.

Abstract: A linear compressor is provided that may include a shell having a cylindrical shape, a compressor main body inserted into the shell, a first shell cover coupled to a rear end of the shell, a first support coupled to a front end of the compressor main body that supports the front end of the compressor main body, and a second support that couples a rear end of the compressor main body to the first shell cover and supports the rear end of the compressor main body. The first support may include a support head coupled to a center of the front end of the compressor main body, and a pair of dampers having both ends respectively coupled to the support head and an inner circumferential surface of the shell.
