Abstract
A compressor cylinder head cast as a single piece casting to include a cylinder bore portion and a cylinder head. The cylinder head is cast with respective recesses for accommodating an intake valve and a discharge valve, such intake and discharge valves being identical in form and shape and, therefore, being interchangeable so that, during assembly of the cylinder head, no particular attention need be given to which valve is placed in which recess.
