SCROLL COMPRESSOR

摘要

A scroll compressor includes a fixed scroll and an orbiting scroll. Each of the fixed and orbiting scrolls includes an end plate and a spiral wrap standing on a front surface of the end plate. The scrolls are arranged such that the front surfaces of the end plates face each other and the wraps are engaged with each other. The orbiting scroll eccentrically rotates, without turning on an axis thereof, with respect to the fixed scroll to compress fluid in compression chambers respectively formed inside and outside the wrap of the orbiting scroll. Each wrap is formed in a shape such that at least one of the compression chambers serves as a rate-reduced compression chamber where a volume change rate thereof is reduced in a middle of a compression phase.
