Abstract
A gas compressor comprises a fixed scroll member and a movable scroll member. A plurality of crescent working chambers are defined between the scroll members so that the volume of the working chambers varies when the scroll members are relatively moved. The compressor has a container which seals a power source and the scroll members and forms inner spaces therebetween. An intake port for drawing a gas from the exterior of the container into the working chambers is formed in the outer peripheral region of the fixed scroll member, and an axial port is formed in the inner region of the fixed scroll member so that the working chambers communicates therewith.
