DRIVING PART FOR VARIABLE-CAPACITY COMPRESSOR

WIPO Patent Application WO/2018/034410

A1

A driving part for a variable-capacity compressor, according to the present invention, comprises: a driving shaft (100) of which one end is connected to an engine pulley so as to receive driving power; a support balancer (300) coupled to one side of the driving shaft (100) at a pulley side and supporting a thrust bearing; a swash plate (500) disposed to be spaced from the support balancer (300), and adjusting a refrigerant discharge amount and pressure according to an inclination angle; a hinge part (700) for connecting the support balancer (300) and the swash plate, and transmitting the rotating power of the driving shaft (100) to the swash plate (500); and a friction ring module for generating friction force between the friction ring module and the driving shaft (100) so as to control the inclination angle of the swash plate (500) in a low-flow condition. According to the present invention, the friction ring module is provided so as to prevent hunting occurring in the low-flow condition, while maintaining controllability.
