Abstract
PURPOSE: To make appropriate the amount and velocity of ejected oil flow through an oil jet nozzle for cooling the piston of an internal combustion engine and improve the effect of the cooling of the piston, by constricting a pipe to make a nozzle hole of prescribed shape.
CONSTITUTION: A pipe 1 for an oil jet nozzle for cooling a piston is constricted to change the inside diameter of the tip of the pipe so that a straight passage 3 of small diameter and a divergent open passage 4 continuous to the former passage are defined. When the inside diameter of the pipe 1 is d1, the inside diameter of the straight passage 3 is d2, its length is l1 and the total length of the straight passage 3 and the open passage 4 is l2, dimensional relationships d2= (0.35W0.6)d1, l2=(2W4)d2 and l≥0.5l2 are set to make the amount and velocity of flow of cooling oil so appropriate that the cooling oil is ejected to a prescribed position without mixing bubbles in the oil and diffusing it.
