Rotary compressor having an aluminum body cast around a sintered liner

摘要

A rotary compressor is provided for use in an air conditioner of an automobile. This compressor includes a cylinder having a cylindrical inner wall portion composed of aluminum alloy filled into the pores of a sintered liner composed of iron series metallic fibers, or into the pores of a blister metal liner. With this arrangement, sliding abrasion between the cylindrical inner wall face and the vanes, and deformation thereof by gas compression forces and high temperatures, can be prevented.
