Reverse rotation prevention for scroll compressors |
September 10, 2002 |
| In a scroll compressor, under conditions favoring reverse operation, the scroll wraps are separated so as to provide a continuous, unimpeded path through the scrolls. Spring bias, a repositioning of driving contact areas and/or force areas can be used singly or in combination to cause |

Compressor sound suppression |
August 4, 2009 |
| A compressor apparatus has a housing (22) having first (53) and second (58) ports along a flowpath. One or more working elements (26, 28) cooperate with the housing to define a compression path between suction and discharge locations along the flowpath. A check valve (70) has a valve |

Compressor |
November 29, 2005 |
| To counter downstream oil infiltration through a shaft seal, a small portion of the compressed fluid is diverted from downstream to upstream through a passageway in a rotor. The diverted fluid is introduced to a space at a downstream side of the seal. An exemplary implementation is in |
