Abstract
A relatively small diameter scroll type compressor is disclosed. The axial center of the compressor's shell is displaced from the involute center of the fixed spiral element in a direction towards the base end portion of the orbital scroll. More specifically, the displacement distance (X) is in the range of: 1/2R.sub.or <X.ltoreq.1/2R.sub.or +1/2(t+c), wherein 't' is the thickness of a base end portion of the orbiting spiral element and 'c' is the minimum clearance between an outer wall of the orbital scroll's base end portion and the inner wall of the shell.
