Abstract
A scroll-type compressor unit which includes fixed and orbiting scroll members contained within a cylindrical housing. Each scroll member has an end plate and a spiral element. In order to reduce the radius of the cylindrical housing, the end plate of the orbiting scroll member is a circular plate having a radius of (a-R/2), and the center of the end plate of the orbiting scroll member is offset from the center of the spiral element affixed thereto, assuming that the radius of the orbital motion of the orbiting scroll member is R, and that the distance between the center and the terminal end of each spiral element is a. Furthermore, the fixed scroll member is so disposed in the cylindrical housing that the center of the spiral element thereof is offset from the center of the cylindrical housing towards the terminal end of the spiral element thereof by R/2. In this arrangement, the radius of the cylindrical compressor housing is further reduced.
