20150037190 | OLDHAM COUPLING WITH ENHANCED KEY SURFACE IN A SCROLL COMPRESSOR - An Oldham coupling structure for a scroll compressor decreases Oldham coupling pressure loading without increasing compressor diameter or significantly increasing orbiting scroll or Oldham coupling inertia. The Oldham coupling key height and area are increased by recessing the key face into the ring portion of the Oldham coupling, increasing the key height and adding pads to the involute side of the orbiting scroll base plate to extend the key slot, potentially resulting in reduced compressor diameter and/or reduced orbiting scroll and Oldham coupling inertia. | 02-05-2015 |
20150093275 | Scroll Type Fluid Machine - To fasten an auxiliary crank for prevention of autorotation of an orbiting scroll to a compressor-casing side bearing in a scroll compressor, a tool must access from a motor side to a compressor casing so as to fasten the auxiliary crank to the compressor-casing side bearing. Therefore, fastening between the auxiliary crank and the bearing cannot be made after a motor section and a compressor body are fastened together. This necessitates the steps of: separating the compressor body from the motor section; fastening the auxiliary crank to the compressor casing; and then fastening the compressor body and the motor section together. A compressor-motor integrated scroll compressor cannot be assembled in sequential steps, entailing increased assembly costs and lowered maintenability. | 04-02-2015 |

With such a configuration, an end of the fixed wrap may not interfere with the orbiting wrap at an arc compression surface of the orbiting wrap, but rather, be inserted into the interference prevention portion. Accordingly, occurrence of a gap between the fixed wrap and the orbiting wrap may be prevented, and thus, compression efficiency enhanced. | 11-26-2015 |
