Purpose, Function
The oil jet valve injects engine oil on the back of the piston to cool the piston.
Construction
The oil jet valve is installed into the cylinder block.

The oil jet valve is built into the check ball and spring.

Operation
1. When the oil pressure applied to the check ball exceeds the spring force, the check ball and spring are pressed down.
2. The oil passage is opened to the nozzle and engine oil is injected to the back side of the piston.

3. When the oil pressure applied to the check ball is lower than the spring force, the spring presses up the check ball.
4. The oil passage to the nozzle is closed and the injection of engine oil stops.
