Abstract

A scroll compressor includes a fixed scroll fixed inside a housing, an orbiting scroll configured to orbit engaged with the fixed scroll, a rotary shaft configured to allow the orbiting scroll to orbit by supporting the orbiting scroll with an eccentric shaft eccentric from a main shaft, and a slide bush portion installed between a bearing of the orbiting scroll and the eccentric shaft and according to a rotational speed of the rotary shaft, configured to change a pressing force of the orbiting scroll applied to the fixed scroll by allowing an eccentricity to be changed by a gas load applied to the orbiting scroll.

Description

technical field [0001] The present disclosure relates to a scroll compressor. Background technique [0002] A scroll compressor operates as follows. A fixed scroll and a movable scroll orbiting around the fixed scroll are provided, and spiral-shaped wraps are respectively formed on surfaces of face plates of the fixed scroll and the movable scroll, and the surfaces face each other. A plurality of compression chambers are formed when the scrolls are engaged with each other, and a sliding sleeve having a sliding surface having a predetermined angle with respect to a load direction of gas in the compression chamber is provided in an eccentric shaft of a rotating shaft driving the movable scroll. Therefore, when a load of gas is applied in the compression chamber, the eccentricity of the eccentric shaft increases. [0003] When the scroll compressor adopts such a structure that when a gas load is applied in the compression chamber, the eccentricity of the movable scroll increa...
