Abstract

전자펌프의 내부압력을 배제하는데 반려량을 종래 보다도 적게하는 내부압력 배재기구를 제공한다. 전자펌프에 있어서, 배출변 보다 하류에서 흡입밸브의 상류에 이르는 반려유로의 도중에 확대된 공간을 형성하고 그 공간내에 플런저를 배치하고 이 플런저에는 오리피스를 형성하며, 또 플런저에 스프링으로서 부세시켜 고압측과 대항하고 있음과 동시에 펌프가동시에 플런저의 시이트가 펌프 본체에 당접하고 펌프정지시에 플런저의 시이트가 펌프 본체에서 떨어져서 내부압을 배제하도록 한 것이다.The present invention provides an internal pressure exhaust mechanism that reduces the amount of the internal pressure of the electromagnetic pump compared to the conventional one. In the electromagnetic pump, an enlarged space is formed in the middle of the return passage from the downstream side of the discharge valve to the upstream side of the intake valve, the plunger is disposed in the space, an orifice is formed in the plunger, and the plunger is biased as a spring to pressurize the high pressure side. At the same time, the sheet of the plunger abuts the pump body when the pump is running, and the sheet of the plunger falls off the pump body when the pump is stopped to exclude the internal pressure.
