  • Compressor valve plate
    Patent number: 7040877
    Abstract: A valve plate assembly includes an upper valve plate, a lower valve plate, an annular spacer and a center spacer. The annular spacer is located between the upper and lower valve plates and around the outer periphery of the upper and lower valve plates. The center spacer is located at approximately the geometric center of the valve plate assembly to provide additional support for the valve plate assembly.

  • Compressor suction reed valve
    Patent number: 6823891
    Abstract: A suction reed valve includes a central ring shaped body having a pair of tabs extending radially outward. One of the pair of tabs is fixed to a valve plate and the other tab is free to move. A necked down region is located between the fixed tab and the central ring shaped body to facilitate the bending/deflection of the suction reed valve.
