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.
