A compressor capable of damping the suction pulsation or discharge pulsation thereof with a simple structure, wherein either of a suction chamber and a discharge chamber formed at the center of a rear head is allowed to communicate with a corresponding port through a tunnel-shaped communication path and a muffler space is formed between the tunnel-shaped communication path and a pipe connection part for connecting the port thereto, whereby, when the communication path allows the suction chamber to communicate with the pipe connection part of the suction port, the suction pulsation can be suppressed or prevented and, when the communication path allows the discharge chamber to communicate with the pipe connection part of the discharge port, the discharge pulsation can be prevented.
