<p>PURPOSE: To realize the compressor which can attenuate vibration and noise to a great extent, and also can exhibit stable exhaust capacity by letting the opening/closing of an exhaust valve be smoothly and quickly operated. CONSTITUTION: In the compressor equipped with each piston 18 which is disposed in a plurality of cylinder bores 19 lined up in the circumferential direction, each cylinder head 3 having a suction chamber 23 and an exhaust chamber 24 inside, each valve plate 30 which is interposed between the cylinder head 3 and the cylinder bore 19, and provided with an exhaust hole 27 communicating the cylinder head 3 with the exhaust chamber 24, and with a retainer 30 controlling the opening of an exhaust valve 28, the compressor comprises the anti- retainer abutting surface 28a of the exhaust valve 28 set in position to be flush with the surface 30a at the exhaust chamber side of the valve plate 30, or to be close to the cylinder bore 19 side when the exhaust valve 28 abuts with a retainer 30.</p> |
