WIPO Patent Application WO/2019/229989

Kind Code:

A1

Abstract:

This scroll compressor comprises a stationary scroll having a stationary spiral body erectly provided on a stationary base plate and an oscillating scroll having an oscillating spiral body erectly provided on an oscillating base plate, the scroll compressor compressing a refrigerant inside a compression chamber formed by intermeshing of the stationary spiral body and the oscillating spiral body. Either the outside curve or the inside curve of each of the stationary spiral body and the oscillating spiral body is an involute curve of a base circle and defined by formula (1) and formula (2) in an x-y coordinate system using an involute angle θ. The radius a(θ) of the base circle in formula (1) and formula (2) is a function that varies according to a sine wave or a cosine wave having a period of π (rad) with respect to the involute angle θ. Formula (1): x = a(θ) (cos θ + θ sin θ) Formula (2): y = a(θ) (sin θ - θ cos θ)
