Abstract

A linear compressor includes a cylinder, a discharge valve, a valve spring pressing the discharge valve to close one side of the cylinder, and a spring support portion providing a support point for the valve spring to press the discharge valve. The valve spring includes a first spring arm whose center is connected to the discharge valve and extending spirally, a second spring arm spaced apart from the first spring arm by a predetermined distance with respect to an axial direction of the cylinder and extending spirally toward an outer portion according to a shape of the first spring arm, and a rubber damper connecting the first spring arm and the second spring arm and fixing relative positions of the first spring arm and the second spring arm.
