ABSTRACT:
A crankcase oil spray nozzle for cooling the crown of a piston of an internal combustion engine is assembled from relatively few stamped principal housing components which are assembled in a sandwich-like, low-profile configuration. The components cooperate to form a nozzle passageway which extends from an integrally formed well to the nozzle orifice. The well houses a check valve assembly. The nozzle components cooperate to define an internal edge filter.
