Diesel engine electromagnetic fuel injector. |
摘要 |
<p>An injector comprising a plunger (1) for controlling fuel passage between an injection chamber (3) and at least an injection orifice (4) formed in an injection nozzle (5); and an electromagnetic fuel metering valve (6) for controlling fuel passage through a drain orifice (7) between a control chamber (8), supplied with fuel under pressure, and a low-pressure chamber (11), so as to reduce the fuel pressure in the control chamber (8) to a given value and so displace the plunger; characterised by the fact that pressurized fuel is supplied to the injection chamber (3) and control chamber (8) by means of a single fitting (13) connected to a supply pipe (14) and coming out inside a supply orifice (15) formed in the injector body (2) and communicating with the control chamber (8) and a duct for supplying fuel to the injection chamber (3).</p> |
