<p>PURPOSE:To reduce noise and discharging pulsation, and enhance uniform passage of refrigerant in respective ports. CONSTITUTION:Inside a valve plate 6 which partitions a bore 2a, a suction chamber 10, and a discharging chamber 12, there are formed ring-shaped flat valve seat surfaces 6b, 6i whose ports 6a, 6h are opened, and cylindrical-hollow valve chests 6d, 6k surrounded, including retainers 6c, 6j which are opposed to and separated from the valve chests 6b, 6i. Moreover, flat plate type valve bodies 27, 31 are fitted loosely in the valve chests 6d, 6j. When difference pressure is generated in a range between which the ports 6a, 6h are held, the valve bodies 27, 31 moves with the pressure difference to open and close the ports 6a, 6n.</p> |
