Abstract

본 발명은 자동차 엔진에 사용되는 로터리식 오일펌프에 관한 것으로, 펌프내에 바이패스 회로를 갖도록 한 로터리식 오일펌프에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary oil pump used in an automobile engine, and to a rotary oil pump having a bypass circuit in the pump.

본 발명은 로터리식 오일펌프의 내부로터에 스프링으로 탄지된 플런저를 내부로터의 원심력에 의해 자동되도록 함으로써 로터리식 오임펌프의 내부에 바이패스 회로를 갖도록 한 것으로, 별도의 바이패스 밸브를 설치하지 않아도 되므로 가격절감이 되고, 잉여오일을 오일팬으로 회송하지 않아도 되므로 이에 다른 에너지 손실을 초래 하지 않으며, 오일펌프 내부의 압력차를 작게 하여 맥동현상이 방지되는 잇점도 있다.The present invention is to have a bypass circuit inside the rotary oil pump by making the plunger carried by the spring to the inner rotor of the rotary oil pump by the centrifugal force of the inner rotor, without having to install a separate bypass valve Therefore, it is possible to reduce the price, and does not cause the excess oil to be returned to the oil pan, which does not cause other energy loss, and also has the advantage of preventing the pulsation phenomenon by reducing the pressure difference inside the oil pump.
