<p>PROBLEM TO BE SOLVED: To provide an oil jet capable of gradually or stepwise changing an oil discharge amount when an engine speed of an internal combustion engine or an oil pressure of a main oil passage is low and high without occurrence of abrasion of an inner wall surface caused by collision of a ball valve to an inner wall surface of a hollow part.SOLUTION: An oil jet 40 includes a housing 21, a nozzle 22, a valve mechanism and a ball supporting member 41. A hollow part 23 having an upper opening 27, a small diameter part 25 communicated with a lower end of the upper opening, and a large diameter part 26 communicated with a lower end of the small diameter part 25 is formed in the housing 21. The ball supporting member 41 has a sleeve 43 coaxially disposed in an inside of the hollow part 23. A horizontal hole 44 is formed on a side wall of the sleeve 43, and in an extended direction of a center axis of the sleeve 43, a portion of the sleeve 43 upper than an upper end of the horizontal hole 44 is disposed in the small diameter part 25, and a portion in which the horizontal hole 44 is formed is disposed in the large diameter part 26.</p> |
