Abstract
An oil jet piston cooling device which directs a stream of oil against the inside of a piston of an internal combustion engine. It comprises a hollow body member and an arcuate tubular spout member. The body member is a stepped hollow cylindrical member with an internally valved inlet opening on its smaller diameter upstream end. The smaller diameter body section defines a first portion of an entrance chamber. A second portion of the entrance chamber is defined by a coaxially disposed cylindrical upstream end section of the tubular spout member, which end section is fitted tightly inside the larger diameter section of the body member. The cross sectional area of the interior of each section of the device is equal to or greater than the cross sectional area of each succeeding section taken from inlet to outlet and the passageway is streamlined to reduce tuburlence. The device is designed to have its body end inserted into a bore that communicates with an oil artery on the pressure side of the bearing lubricating oil circulation system of the engine.
