Split crankcase radial automotive compressor - has cast aluminium crankcase axially split in half, each half having semi-cylindrical recesses forming cylinders when assembled

摘要

The radial compressor for use in automotive air conditioners has a cast aluminium crankcase which is split along a plane axially passing through the centre lines of the radially oriented cylinders. Each of the crankcase halves has a number of radially extending semicylindrical recesses which, when assembled, form the cylinders. Cylindrical cylinder liners are preassembled to the pistons and this assembly is then placed in one of the crankcase halves with the liners being received in their respective semicylindrical recesses. The second crankcase half is then secured to the first, again with the semicylindrical recesses overlying the cylinder liners. The distal ends of the liners are sealed by annular flanges which are clamped between the crankcase and the valve plate assemblies located at the ends of the cylinders.
