Abstract
A compressor is described having front and rear cylinder blocks coupled to each other with a crank chamber defined therebetween. A swash plate is mounted on a drive shaft in the crank chamber. Double-headed pistons reciprocate in pairs of aligned cylinder bores. The swash plate divides the crank chamber into a plurality of sections. Holes formed in the swash plate permit flow of the refrigerant between the chamber sections. Recesses are formed radially inward and outward of a cam shoe contacting surface of the swash plate.
