Document Type and Number:
WIPO Patent Application WO/2018/201827
Kind Code:
A1
Abstract:
A rolling piston rotary compressor, comprising a housing (1), a compressing assembly, and a support assembly; the compressing assembly comprises a crankshaft (3), a cylinder (2), and a piston (5), the crankshaft (3) being internally provided with a first oil hole (34) which extends along the axial direction of the crankshaft (3); the support assembly comprises an upper support portion (4) for fixing the crankshaft (3); the crankshaft (3) is further internally provided with a second oil hole (35) which is in communication with the first oil hole (34) and the outer surface of the first portion (36) on the crankshaft (3) where the crankshaft (3) fits inside the upper support portion (4). Said rolling piston rotary compressor is provided with a horizontal oil hole located on the portion where the upper support portion (4) fits onto the crankshaft (3), so as to lubricate the portion where the upper support portion (4) fits onto the crankshaft (3), thereby reducing the wear of a corresponding portion of the crankshaft (3), improving the reliability of the rolling piston rotary compressor.
