| RE39346 |
Scroll compressor with lubrication of seals in back pressure chamber |
October 17, 2006 |
| A scroll compressor lubrication system includes a number of embodiments where lubricating oil impinges off surfaces adjacent to the orbiting scroll. The impinged oil creates a lubrication mist, which is deposited on the back surface of the orbiting scroll baseplate. The surface of the |
| RE37837 |
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 |
