Abstract

In a scroll type compressor in which a compression mechanism compresses a gaseous fluid with moving the gaseous fluid along a spiral path to produce a compressed gas, an escaping path is provided for escaping the compressed gas from the compression mechanism at an intermediate portion of the spiral path. A pressure transmission path transmits pressure of the compressed gas to a valve mechanism which is for controlling an open and an close of the escaping path. The pressure transmission path has a delay mechanism for delaying transmission of a change of the pressure to the valve mechanism.
