Abstract
A scroll compressor utilizes scroll wrap profiles which are designed with a rapid compression scroll wrap profile. This profile utilizes a shorter wrap and lower vane aspect ratios during the compression process. The non-orbiting scroll member is integrated with the main bearing housing. The drive shaft extends through the main bearing housing, through the non-orbiting scroll member and through the orbiting scroll member. In one embodiment, a counterweight is disposed adjacent the orbiting scroll member. In another embodiment, and upper bearing housing is disposed adjacent the orbiting scroll member. In yet another embodiment, an upper bearing housing is disposed adjacent the orbiting scroll member with a counterweight disposed adjacent the upper bearing housing.
Claims14
A scroll compressor comprising:
- an orbiting scroll member having an orbiting end plate defining a discharge port and an orbiting spiral wrap extending from said orbiting end plate;
- a non-orbiting scroll member having a non-orbiting end plate and a non-orbiting spiral wrap extending from said non-orbiting end plate;
- said non-orbiting spiral wrap being intermeshed with said orbiting spiral wrap;
- a bearing housing extending from said non-orbiting end plate in a direction opposite to said non-orbiting spiral wrap;
- a drive member for causing said orbiting scroll member to orbit relative to said non-orbiting scroll member whereby said spiral wraps create pockets of progressively changing volume between a suction pressure zone and a discharge pressure zone;
- said drive member extending through said bearing housing, said non-orbiting scroll member and said orbiting scroll member;
- and
- a counterweight attached to said drive member at a position adjacent said orbiting end plate, said counterweight rotating adjacent said discharge port to define a discharge valve for controlling fluid flow through said discharge port.
