  • Scroll-type compressor having improved pressure equalizing passage configuration
    Patent number: 5833442
    Abstract: A scroll-type compressor has a scroll plate with at least first and second pressure equalizing passages formed in its end plate such that the first and second pressure equalizing passages will be in the same crescent shaped pocket during at least a portion of a crescent shaped pocket's radially inward movement. The minimum pressure in a back pressure pocket will be adequate to maintain a good seal, any pressure increases will increase in accordance with the increased pressure in the crescent shaped pockets. At no point are both of the pressure equalizing passages blocked and, therefore, the pressure in the interior space does not overwhelm the effective functioning of the back pressure pocket.
