PROBLEM TO BE SOLVED: To provide an inexpensive compressor capable of monitoring both pressures on a delivery side and a suction side. SOLUTION: The outer periphery of a front housing 1 is provided with a relief valve 27 for high pressure connected to a delivery chamber 13 via a connection passage 26, and a relief valve 29 for low pressure connected to a suction chamber 12 via a connection passage 28. The relief valve 27 for high pressure and the relief valve 29 for low pressure have the same structure, but the relief valve 27 for high pressure uses a thin opening pressure adjusting shim 37 to increase opening pressure and the relief valve 29 for low pressure uses a thick opening pressure adjusting shim 37 to decrease opening pressure.
