F02M47/02 - CPC Classification

Classification description:

Fuel-injection apparatus operated cyclically with fuel-injection valves actuated by fluid pressure of accumulator-injector type, i.e. having fuel pressure of accumulator tending to open, and fuel pressure in other chamber tending to close, injection valves and having means for periodically releasing that closing pressure

Sub-classes:

F02M47/022 » {Mechanically actuated valves draining the chamber to release the closing pressure} 6
F02M47/025 » {Hydraulically actuated valves draining the chamber to release the closing pressure} 27
F02M47/027 » {Electrically actuated valves draining the chamber to release the closing pressure} 669
