SYSTEM AND METHOD FOR REDUCING NOISE IN MULTI-CAPACITY COMPRESSORS

摘要

A method and system is provided for reducing chatter in multi-capacity compressors 101 having disengageable eccentric structures. The multi-capacity fluid compressor 101 includes a compression chamber having a discharge end and an inner surface 303. The compressor 101 also includes a compression member 300, 700 having a disengageable eccentric structure 203, 709 allowing the compressor to provide discrete compression capacities. A valve portion 307 is disposed adjacent to the discharge end of the compression chamber and is arranged and disposed to discharge a compressed fluid when the compression member has completed. A discharge arrangement 311, 401, 501, 601 is arranged and disposed to discharge at least a portion of fluid 309 remaining in the compression chamber at the completion of the compression cycle. The discharge of fluid 309 limits rotational acceleration of the disengageable eccentric structure 203, 709 and chatter.
