    (54) Spray nozzle assembly for piston cooling


    (57) A crankcase oil spray nozzle (10) for cooling the crown of a piston (16) of an internal combustion engine (12) is assembled from relatively few stamped principal housing components (30,40,50) which are assembled in a sandwich-like, low-profile configuration. The components (30,40,50) cooperate to form a nozzle passageway (48) which extends from an integral­ly formed well (42) to the nozzle orifice (47). An indentation is coined in one component to form the nozzle (48) passageway and the nozzle orifice (47).
