ABSTRACT:
A scroll compressor includes an orbiting scroll member having an orbiting end plate defining a discharge port and an orbiting spiral wrap extending from the orbiting end plate. The compressor also includes a non-orbiting scroll member having a non-orbiting end plate and a non-orbiting spiral wrap extending from the non-orbiting end plate. The non-orbiting spiral wrap is intermeshed with the orbiting spiral wrap. Furthermore, a bearing housing extends from the non-orbiting end plate opposite from the non-orbiting spiral wrap, and a drive member causes the orbiting scroll member to orbit relative to the non-orbiting scroll member whereby said spiral wraps create pockets of progressively changing volume between a suction pressure zone and a discharge pressure zone. The drive member extends through the bearing housing, the non-orbiting scroll member and the orbiting scroll member. Also, the scroll compressor includes a discharge valve for controlling fluid flow through the discharge port.
