Claim 15:
16. A compressor system comprising:
a compressor operable to compress a refrigerant, the compressor comprising:
a shell;
a driveshaft including a driveshaft body, an eccentric body, and a recess defined at least in part by a back surface;
a non-orbiting scroll disposed within the shell;
an orbiting scroll disposed within the shell, the eccentric body drivingly engaged with the orbiting scroll;
a bearing housing fixed within the shell;
a bearing supported by the bearing housing, the bearing axially spaced from the non-orbiting and orbiting scrolls; and
an unloader at least partially received within the recess of the driveshaft, the unloader having inner and outer surfaces, the outer surface is engaged with the bearing, and wherein at least one of the back surface and the inner surface is curved and the unloader is pivotable within the recess relative to the driveshaft, wherein the outer surface of the unloader is curved and has a radius of curvature that is substantially the same as a radius of curvature of the driveshaft;
a condenser downstream of the compressor; and
an evaporator downstream of the condenser.
