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: The present disclosure provides a pulsation dampening assembly for a compressor having an outlet port configured for supplying compressed refrigerant from a compression mechanism of the compressor. The pulsation dampening assembly includes a pulsating disc and a spring. The pulsating disc and the spring are disposed within the outlet port. The pulsating disc includes a plurality of apertures in fluid communication with the compression mechanism. The spring includes a first end engaging the pulsating disc and a second end engaging the outlet port. The pulsating disc is translatably disposed within the outlet port between an operative state and an inoperative state.
