ABSTRACT:
A cylinder block of a rotary slide vane compressor, having an eccentric inner surface with split inner sleeve members embedded therein and in slidable contact with the vanes. The method for making the cylinder block comprises the steps of preparing an inner sleeve original form of a ferrous material and having a circumferentially closed integral portion. This original form is embedded in the inner surface of the cylinder of aluminum alloy during the step of casting the cylinder block, and thereafter, the cast cylinder block is machined together with the original form to cut away the circumferentially closed integral portion and thereby separate the original form into a plurality of split inner sleeve members.
