Abstract: Provided are a discharge plenum integrated with a valve stopper and a linear compressor including the discharge plenum. The valve stopper includes a radial member that extends radially and an axial member that extends axially from a radial inner end of the radial member. The axial member may have a tubular shape. The axial member may define a slot flow path that extends axially. The radial member may include a peripheral hole that extends axially. The radial inner side of the radial member may define a central hole of the axial member. The slot flow path and the peripheral hole may minimize a pressure drop and energy loss of a high-pressure fluid flowing from a compression portion to a discharge portion.

Abstract: A piston for a compressor and a compressor including the same are disclosed. The piston is used in a compressor which compresses and discharges refrigerant suctioned into a cylinder. The piston includes a cylindrical slider and a head. The slider has an outer diameter corresponding to an inner diameter of the cylinder and defines a suction space in which the refrigerant suctioned in the cylinder is received. The head is coupled to the slider, in which a compression space is provided in the front and a suction space is provided in the rear, and in which a suction port communicating with the suction space and the compression space is formed, in which the head includes an inner body and an outer body surrounding the inner body, and the suction port is formed between the inner body and the outer body.
