ABSTRACT:
A piston squirter system for an internal combustion engine includes an oil reservoir, a variable displacement pump, and, for each cylinder, a piston squirter that sprays oil onto a piston for cooling and lubricating. A gallery connects the variable displacement pump to the piston squirters. The variable displacement pump receives oil from the oil reservoir and distributes the oil through the gallery to the piston squirters at a flow rate according to pressure required. The gallery does not require a relief valve and the piston squirters do not require check valves.
