Abstract
An automotive A/C compressor has a novel discharge valve design that can be easily installed even though the compressor shell is made up of only two housings, each of which integrates head, cylinder bore and discharge chamber, leaving no access between the integral head and bore. A plurality of cylindrical mounting bosses are molded into the heads, one central to each bore. The plane in which the end of each boss is located can be machined independently from the axially overlapping cylinder bore, which assures an intersection of the two. The discharge valve is sized to fit through the other end of the bore into abutment with the boss, and carries a seal that is likewise assured of sealing contact with the bore.
