  • Air conditioning reed valve support seat
    Patent number: 5884665
    Abstract: An improved reed valve assembly for a compressor (10) includes a substantially annular reed tip support seat (36) which nonconcentrically surrounds a round discharge port (32). The radial width of the support seat (36) varies continually from a greatest width nearest the distal edge of the reed tip (24') to a least width diametrically opposed thereto. The greatest width is sufficient to support the reed tip (24') in the area where it needs the greatest support, but is narrower everywhere else, so as to reduce contact area, noise and opening resistance.
