Abstract

PURPOSE: To prevent the reduction of volumetric effciency due to errors produced in manufacturing a scroll member by a method wherein the wall thickness of the outer circumference of a scroll body is made slightly tinner than that of the control part and reliable linear contact is conducted between the scrolls in a pocket part of high pressure fluid.
CONSTITUTION: The wall thickness at the neighborhood of the central part of the scroll bodies 132, 142 of both scroll members is provided slightly thicker by α than that at other parts so that a perfect linear contact can be obtained. In this manner, although a slight error ΔE occurs on the wall worked of another part, sealing is not effected in the central part as long as ΔE<2α and the reduction of the volumetric efficiency due to leakage from non-contact parts on the outer circumference part can be restricted. And besides, the distortion of a scroll due to the rise of temperature produced in running of the compressor can be absorbed by the difference α of the wall thickness.
