ABSTRACT:
A fluid lubricating circuit for an internal combustion engine which can effectively damp or reduce fluid pressure pulsation in the circuit. To this end, the circuit includes a pressure damper connected between a hydraulic pump and an oil cooler. The pressure damper has formed therein a pair of orifices disposed in a spaced relation from each other in a direction of fluid flow and a damping chamber between the orifices.
