ヤオイルポンプ。 This is a plunger oil pump in which a plunger 5 rotates and reciprocates in a cylinder 2 bored in a pump housing 1 made of an aluminum material to perform a pumping action. The drive means for the plunger 5 is composed of a worm wheel 9 formed in the pump housing 1 and an end face cam 6 formed in the end face of the plunger 5 to reciprocate along with the rotational movement. In the one that is exposed to the outside, the plunger 5 has the drive means;
The driving part 5 is divided into a driving part 5-2 consisting of a shaft neck part that fits into the cylinder 2 and supports the driving means, and a pumping part 5-1 which performs a pumping action by rotating and reciprocating motion. -2 is made of steel material, and the pump action portion 5-1 is made of aluminum material and hard alumite treatment is applied to the surface, and the pump action portion 5-1 is connected to the pump housing 1. A plunger oil pump in which a sealing member 16 for shielding from the outside is disposed between the inner surface of the cylinder 2 and the plunger 5.
