    Abstract: A compressor may include a shell assembly, a first scroll, a second scroll, a driveshaft, and a bearing. The first scroll includes a first end plate and a first spiral wrap extending from the first end plate. The second scroll includes a second end plate and a second spiral wrap extending from the second end plate. The spiral wraps engage each other to form fluid pockets. The driveshaft may engage one of the scrolls. The bearing supports the driveshaft for rotation relative to the shell assembly. The bearing includes first and second axial ends and an aperture extending through the first and second axial ends. The driveshaft extends through the aperture. The aperture is defined by an inner diametrical surface of the bearing. The inner diametrical surface may include a tapered portion that extends radially outward as the tapered portion extends axially toward the first axial end of the bearing.

    Abstract: A compressor may include a shell, first and second scroll members, a floating seal, a muffler plate, and a wear ring. The shell defines a discharge chamber and a suction chamber. The floating seal may sealingly engage the second scroll member. The muffler plate defines the discharge chamber and the suction chamber. The wear ring may sealingly engage the muffler plate and the floating seal such that the wear ring, the muffler plate, and the floating seal fluidly isolate the discharge chamber from the suction chamber. The muffler plate may include an axially facing surface that contacts the wear ring. The axially facing surface may include an annular recess. The wear ring may at least partially cover the annular recess. The annular recess may provide clearance between the muffler plate and the wear ring to allow the wear ring to deflect relative to the muffler plate during compressor operation.

    Abstract: A compressor may include a shell, orbiting and non-orbiting scrolls, an unloader bushing assembly and a drive shaft. The unloader bushing assembly may include a drive bushing and a spring. The drive bushing includes an outer surface engaged with the orbiting scroll and may define an opening extending from a first bushing end to a second bushing end. The spring may include a body disposed within the opening of the drive bushing and may include first and second spring ends with at least a portion of the first spring end extending laterally from the body and overlapping the first bushing end. At least a portion of the second spring end may extend laterally from a body and overlap the second bushing end to secure the spring within the drive bushing. The drive shaft may include a crank pin disposed within the opening of the drive bushing and engaging the spring.

    Abstract translation: 压缩机可以包括壳体，绕动涡卷和非绕动涡卷，卸载器衬套组件和驱动轴。 卸载器衬套组件可以包括驱动衬套和弹簧。 驱动衬套包括与动涡旋件接合的外表面，并且可以限定从第一衬套端部延伸到第二衬套端部的开口。 弹簧可以包括设置在驱动套管的开口内的主体，并且可以包括第一和第二弹簧端部，其中第一弹簧端部的至少一部分从主体横向延伸并与第一衬套端部重叠。 第二弹簧端的至少一部分可以从主体横向延伸并且与第二衬套端部重叠，以将弹簧固定在驱动衬套内。 驱动轴可以包括设置在驱动衬套的开口内并接合弹簧的曲柄销。
