イルポンプ。In an oil pump, the rotational force generated by the engine gives a reciprocating motion to the plunger, and the distributor switches the passage between the suction passage and the discharge passage.
A first check valve that allows flow only in the discharge direction is disposed in the discharge passage, and a first check valve that allows flow only in the discharge direction is disposed in the discharge passage downstream of the first check valve. An oil pump equipped with a second check valve whose opening pressure is weaker than that of the stop valve.
