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.
