摘要： A scroll compressor comprises a fixed scroll member and a revolving scroll member that engage with each other with their centrifugal walls, wherein the revolving scroll member is supported to revolve with respect to the fixed scroll member, but to avoid self-rotation thereof. The spiral-starting portion of the centrifugal wall comprises non-stepped portions formed along curves of null1-null1null and null2-null2null respectively, and a stepped portion formed along a curve null1null-null2null that provides a thickness increase area encompassed by its upper-side curved surface and its lower-side curved surface. The discharge port is located on the end board of the fixed scroll member to partly overlap with the thickness increase area by partly hollowing the lower side of the stepped portion with the prescribed height.

摘要： A scroll compressor for reducing fluid leakage at step portions of scroll members and improving the compression efficiency is disclosed. The reduction of leakage and a high compression efficiency can be realized without increasing the precision in the manufacture of the members. Between the engaged scroll members, a high-pressure space is formed close to the spiral center, and among points at which the spiral walls contact with each other immediately before the innermost closed space communicates with the high-pressure space, the innermost point is defined as a base point. The angular distance from the base point to the outer end of the spiral, measured along the inner-peripheral face of the spiral wall, is approximately 4null rad. The angular distance from the base point to the step portion of each end plate, measured along the inner-peripheral face of the spiral wall, is equal to or more than approximately 3null rad.
