ABSTRACT:
An internal crankcase support for a radial compressor of the scotch yoke type, especially adapted for use in automotive air-conditioners and having a cast crankcase which is split along a plane axially passing through the center lines of the radially oriented cylinders. Each half of the crankcase has a plurality of radially extending semi-cylindrical recesses which, when assembled, form the cylinders. A steel outer housing encloses the crankcase and serves to form the intake and outlet chambers. The housing is formed of two halves which are joined together along a fluid-tight interface and additionally strengthened by means of a plurality of tie rods which pass through openings in the crankcase and clamp the housing halves tightly together. Internal radial support for the crankcase within the housing is provided by a radial support ring secured to the rear housing section and which, upon assembling the housing halves, tightly fits over a circular crankcase shoulder on the rear crankcase half.
