Abstract

〔과제〕〔assignment〕

펌프정지시에 펌프의 내부압을 흡입밸브보다 상류측에 달아나게 하는 것을 목적으로 한다.And aims to cause the internal pressure of the pump to flow to the upstream side of the suction valve when the pump is stopped.

〔해결 수단〕[Solution]

전자코일에 왕복운동되는 피스톤에 의하여 용적변화가 주어지는 펌프실을 흡입밸브를 우회한 리크통로를 설치하여 이 리크통로를 흡입밸브의 상류에 연통시킨 것이다.A leak passage that bypasses the suction port is provided in the pump chamber in which the volume is changed by the reciprocating piston on the electromagnetic coil, and this leak passage is communicated with the upstream of the suction valve.
