Abstract

연료분사펌프는 최소한 하나의 실린더(3)와, 그 내부에서 축방향으로 이동할 수 있는 피스톤(4)으로 이루어진다. 피스톤은 펌프의 송출의 개시를 결정하는 제1미터링에지(5)와 펌프의 송출의 종료를 결정하는 제2미터링에지(7)를 가지고 있으며, 2개의 미터링에지는 실린더(3)의 벽에 형성된 개구(6)와 상호 작용하고, 이 개구는 흡입구(12) 및 배출구(13)에 연결되어 있다. 실린더(3)는 2개의 종단위치 사이에서 펌프하우징(1)의 축방향으로 이동할 수 있도록 펌프하우징(1)에 배설되어 있다. 종단위치 중 하나에 실린더를 유지하기 위하여 , 유압(챔버25)이 그 위에 작용하고, 실린더가 다른 종단위치이면 제거될 수 있다.The fuel injection pump consists of at least one cylinder 3 and a piston 4 axially movable therein. The piston has a first metering edge 5 which determines the start of pump delivery and a second metering edge 7 which determines the end of pump delivery, the two metering edges being formed on the wall of the cylinder 3 Interact with the opening 6, which is connected to the inlet 12 and the outlet 13. The cylinder 3 is arranged in the pump housing 1 so as to be able to move in the axial direction of the pump housing 1 between two end positions. In order to hold the cylinder in one of the termination positions, hydraulic pressure (chamber 25) acts on it and can be removed if the cylinder is in the other termination position.
