PRESSURE CONTROLLED INJECTION WITH SLIDER THROTTLE FOR HIGH-PRESSURE INJECTION

摘要

PROBLEM TO BE SOLVED: To provide an injector easily controllable in a pressure. SOLUTION: This injector injecting fuel under pressure to a combustion chamber inside of an internal combustion engine is such a type that a valve element 6 is made to vertically move in an injector casing 2 using an actuator and a seal seat of a closing element 3 is provided in the injector casing 2 to open/close feed passages 5 and 28 extending from a high-pressure assembly chamber. A continuously working throttle element 31 and a throttle element 30 adjustable by using the valve element 6 are branched from a nozzle feed passage 14 communicated with the nozzle chamber 23.
