Abstract
A housing assembly for a scotch yoke radial compressor especially adapted for use in automotive air-conditioners 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. The tie rods pass through eyelet rivets disposed within the openings in the crankcase. The rivets are clinched so as to secure the crankcase halves together and seal the interface between the crankcase halves in the area of the tie rod openings. The eyelet rivets also serve to provide a guide for the tie rods during assembly for ease in mating the two halves of the housing.
