Abstract
A compressor including a shell, a scroll assembly, and driveshaft. The scroll assembly includes an orbiting scroll including an orbiting spiral wrap and a second opening including a drive bearing disposed therein. The drive bearing is axial aligned with the orbiting spiral wrap. The compressor includes an unloader rotationally connected to the driveshaft body and rotationally supported with a primary bearing.
Claims20
A compressor comprising:
- a shell;
- a motor;
- a scroll assembly positioned within the shell including a first axial side and a second axial side, the scroll assembly comprising:
- a non-orbiting scroll including a non-orbiting spiral wrap, wherein the non-orbiting scroll includes a first opening;
- and
- an orbiting scroll including an orbiting spiral wrap and a second opening having a drive bearing positioned therein, wherein the drive bearing is axially positioned in alignment with the orbiting spiral wrap;
- a driveshaft including a driveshaft body and an eccentric body, the eccentric body positioned within the second opening and drivingly engaged with the drive bearing of the orbiting scroll, the motor operably connected to the driveshaft and positioned on the second axial side of the scroll assembly;
- an upper housing bracket defining a bracket opening;
- a primary bearing positioned within at least one of the first opening of the non-orbiting scroll and the upper housing bracket;
- and
- an unloader rotationally connected to the driveshaft body and rotationally supported with the primary bearing.
