Abstract

A piston cooling jet includes a housing, a nozzle, a valve, a pressure chamber, a pressure adjusting passage, and a filter. The nozzle is provided to project outward from the housing, and capable of spraying oil toward a piston. The valve is capable of moving reciprocally inside the housing, and configured to receive a load due to a hydraulic pressure in an engine-side oil passage applied from a front side of the valve. The valve includes a valve-side oil passage that communicates with the engine-side oil passage. The pressure chamber is defined inside the housing on a back side of the valve. The pressure chamber communicates with the valve-side oil passage. The pressure adjusting passage is disposed between the pressure chamber and a space outside the housing. The filter is disposed in the valve, and configured to remove foreign matter that cannot pass through the pressure adjusting passage from oil passing through the valve-side oil passage.
