Abstract
The invention describes an injector device specifically designed for the injection of an alternative fuel such as LPG, methane, hydrogen or others, in an internal combustion engine. In the injector device, the shutter ensuring sealing in closing condition is separated with respect to the metering means with gauged hole, which perform the function of metering fuel during injection, and it is arranged downstream from said metering means. The shutter is controlled by a solenoid, which is again arranged on the downstream side with respect to said metering means.
Claims11
Fuel injector device for an internal combustion engine, comprising:
- a valve body, having an inlet designed to be connected to a source of pressurized fuel and an outlet designed to be connected with engine intake,
- a shutter cooperating with a corresponding valve seat so as to check the communication between said inlet and said outlet,
- elastic means holding the shutter in its closing position,
- a solenoid for causing a shift of the shutter towards its opening position,
- metering means with gauged hole for metering the amount of fuel getting out of the injector device when the shutter is open,
- wherein said metering means with gauged hole are separated with respect to said shutter and to the valve seat cooperating with it.
