Benefits of technology

This patent is related to a drive unit for a compressor that solves issues with low flow conditions by including a friction ring module. This helps to maintain controllability and prevent hunting, which means the compressor is always running smoothly.

Problems solved by technology

However, this hinge mechanism requires the process of press-fitting the rotor to the rotary shaft, thereby causing complexity of work processes and product structures.
Hence, the drive unit is disadvantageous in terms of weight, process, or price competitiveness.
In addition, the drive unit is disadvantageous in that the gap between components is relatively large due to the clearance of the high mechanism.

Abstract

The drive unit has an effect of maintaining controllability and preventing a hunting problem caused under low flow conditions since it includes a friction ring module.

Description

TECHNICAL FIELD[0001]The present invention relates to a drive unit for a variable capacity compressor, and more particularly, to a drive unit for a variable capacity compressor, which has a simplified structure.BACKGROUND ART[0002]In general, a compressor applied to air conditioning systems sucks refrigerant gas having passed through an evaporator to compress the same to high temperature and high pressure, and then discharges the compressed refrigerant gas to a condenser. As this compressor, there are used various types of compressors such as a reciprocating compressor, a rotary compressor, a scroll compressor, and a swash plate compressor.[0003]The swash plate compressor includes a disc-shaped swash plate that is obliquely installed to a drive shaft rotated by power transmitted from an engine to be rotated by the drive shaft. In addition, the principle of the swash plate compressor is to suck or compress and discharge refrigerant gas by rectilinearly reciprocating a plurality of pi...
