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.
