てなる、 ことを特徴とする内燃機関用潤滑油ポンプ。[Claims for Utility Model Registration] Lubricating oil that rotates a distributor using a worm gear mechanism by obtaining driving force from a driving worm, and performs a pumping action by the sliding movement of a plunger arranged in the axial direction of the distributor. In the pump, a cylinder hole is formed in a penetrating manner along the center of the rotational axis of the distributor, and a cam surface is formed on one end surface of the distributor facing the cylinder hole, and the cylinder hole A piston portion of a plunger is slidably mounted in the pump chamber, and the head of the plunger protrudes beyond the end surface of the distributor and receives a spring biasing force in the returning direction. The rear end surface of the head of the plunger is in contact with the cam surface, and the other end surface of the distributor is recessed with an oil communication groove that is connected to the cylinder hole and extends from the center toward the outer circumference. A suction hole and a discharge hole communicating with the outside of the lubricating oil pump are formed at a distance from each other on a circumferential trajectory drawn by the outer peripheral end of the communication groove by rotation of the distributor. Lubricating oil pump for internal combustion engines.
