Abstract

A compressor is provided and may include a shell, an orbiting scroll, a driveshaft and an unloader counterweight. The orbiting scroll may be disposed within the shell and include a boss portion. The driveshaft may include an eccentric pin and rotate about a longitudinal axis. The unloader counterweight assembly may include a first, a second end, and a longitudinal opening extending therebetween. The eccentric pin of the driveshaft may be disposed within the longitudinal opening at the first end of the unloader counterweight assembly. The boss portion of the orbiting scroll may be disposed within the longitudinal opening at the second end of the unloader counterweight assembly

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 61 / 898,212, filed October 31, 2013. The entire disclosure of the above application is incorporated herein by reference. technical field [0003] The present disclosure relates to a scroll compressor having an unloader counterweight assembly. Background technique [0004] This section provides background information related to the present disclosure which is not necessarily prior art. [0005] Scroll compressors are used in applications such as refrigeration systems, air conditioning systems, and heat pump systems to pressurize and thus circulate the refrigerant within each system. [0006] When the scroll compressor is in operation, the orbiting scroll member with the orbiting scroll member scroll orbits relative to the fixed scroll member with the fixed scroll member wrap to form a moving gap between the sides of the corresponding scroll member. lin...
