  • Publication number: 20100200095
    Abstract: The inclination of the suction reed at the time of sucking the refrigerant can be increased when L/S is not more than 0.25 where S (mm2) represents the area within the periphery of the suction valve seat of the suction reed, and L (mm) represents the length between the support end and the tip on the opening/closing part side of the suction reed. The increased inclination of the suction reed smoothes the flow of the refrigerant into the cylinder bore from the inside of the suction valve seat so as to reduce the suction resistance and the clearance volume, thereby reducing the re-expansion loss. As a result, the refrigerant flow is increased to increase the volumetric efficiency, thereby improving the freezing performance of the hermetic compressor.

  • Patent number: 7631729
    Abstract: A reciprocating compressor includes a compressing unit placed over a motor unit. A crankshaft, which converts rotating action of the motor unit into reciprocating action of a piston of the compressing unit, has (a) a centrifugal pump provided at a lower section of the crankshaft, and (b) a pair of spiral pumps that communicate with the centrifugal pump and have leading grooves running in opposite directions to each other. The crankshaft also includes a pair of eccentric paths at its upper section. The eccentric paths open into an enclosed container and communicate with the spiral pumps respectively. This structure allows production of greater force for transferring lubricant oil regardless of the rotating direction of the crankshaft.
