摘要: A linear compressor includes a shell, a frame in the shell, a cylinder defining a compression space, a piston in the cylinder, a motor assembly that drives the piston, a discharge cover unit defining a discharge space that receives refrigerant from the compression space, a discharge valve that selectively opens and closes the compression space, and a valve spring assembly that provides elastic force that causes the discharge valve to contact a front surface of the cylinder. The discharge cover unit includes a cover housing, the cover housing that couples the frame, a dividing sleeve that extends from an inside of the cover housing in a longitudinal direction of the shell and that divides the discharge space into discharge chambers, and a discharge cover that inserts into the inside of the cover housing and that contacts an end portion of the dividing sleeve.
