发明名称 Piston cooling nozzle
摘要 PCT No. PCT/US91/06408 Sec. 371 Date Sep. 9, 1991 Sec. 102(e) Date Sep. 9, 1991 PCT Filed Sep. 9, 1991.Existing cooling jets used with present day engines must be manufactured and assembled to precisely direct the coolant to the proper location within the engine to insure efficient cooling of the components within the engine. Many of the present day cooling jets include a structural body having a piece of tubing bent in a preestablished configuration to direct the coolant to the appropriate area within the engine. The cooling nozzle (60) of the present invention includes a non-metallic body (64) and a metallic insert (110). The non-metallic body (64) includes a single passage (84) therein which has a first transition area (92) for directing a cooling fluid (50) into a pair of passages (86) to provide smooth, reduced turbulences and reduced eddie currents. The cooling nozzle (60) further includes a second transition area (100) for directing the cooling fluid (50) from the pair of passages (86) into a second pair of passages (94) being of a different cross-sectional area to provide a smooth, reduced turbulences and reduced eddie currents. The metallic insert ( 110) prevents the non-metallic nozzle (60) from being crushed when assembled to the engine (12). Thus, the cooling nozzle (60) of the present invention results in a low cost efficient cooling nozzle (60).
