VORRICHTUNG ZUM VERHINDERN EINES UEBERMAESSIGEN DURCHFLUSSES VON GASFOERMIGEM BRENNSTOFF DURCH EINE EINSPRITZDUESE EINES DIESELMOTORS.

摘要

A device for preventing abnormal flow of gas fuel from a gas fuel injector of a diesel engine. The device has a pipe for supplying a pressurized gas fuel, a fuel injector including a passage connected to the pipe and leading to fuel injection nozzle ports, and a fuel cut-off valve means adapted to close the gas fuel passage upon detection of a reduction of the fuel pressure in the fuel passage. Any abnormal supply of fuel due to stick of the fuel injector is prevented so as to avoid any risk of explosion which otherwise may be caused by the abnormal supply of the gas fuel.
