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.
