SCROLL COMPRESSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18066615 titled 'SCROLL COMPRESSOR
Simplified Explanation
- The patent is for a scroll compressor design. - The compressor includes a rotating shaft coupling portion that extends from the center of an orbiting end plate to overlap with an orbiting wrap. - This allows the eccentric portion of the rotating shaft to be coupled to the wrap. - The design reduces the distance between the bearing reaction force and gas reaction force acting on the orbiting scroll. - This stabilizes the behavior of the scroll and reduces back pressure. - The reduced back pressure decreases friction loss between the scrolls. - The design also allows compression chambers to be formed in the central portion of the orbiting scroll. - This increases the compression ratio and improves volumetric efficiency.
Original Abstract Submitted
A scroll compressor is disclosed. The scroll compressor includes a rotating shaft coupling portion axially extending from a central portion of an orbiting end plate to radially overlap an orbiting wrap, such that an eccentric portion of a rotating shaft is coupled thereto, and a portion of the orbiting wrap may extend from an end surface of the rotating shaft coupling portion facing a fixed end plate. With the configuration, a distance between bearing reaction force and gas reaction force acting on the orbiting scroll can be reduced, to stabilize a behavior of the orbiting scroll and thus reduce back pressure, thereby decreasing friction loss between scrolls. Simultaneously, compression chambers can be formed even in a central portion of the orbiting scroll, which can increase a compression ratio and improve volumetric efficiency.
