Carburettor with independent idling system - has air volume regulating screw with tip projecting into nozzle

Номер: DE0003929025A1
Принадлежит:

The carburettor is for IC engines. It has a throttle flap (4) in intake channel (2), an idling outlet bore (9a), and a main nozzle (8). The nozzle is connected via an adjustable aperture, to a fuel-filled control chamber (7), and the outlet bore is connected to it, via an idling chamber (26) and a non-adjustable aperture (28). An air channel (30) extends from the intake channel in front of the throttle flap, to the idling chamber. The flow section of the air channel is adjustable by an air volume regulating screw (24). The pref. conical tip (31) of the screw forms an adjustable ring gap with the air channel wall. USE - Carburettor for IC engine.

The tapered tip of a rod is disposed within a jet of a carburett or by displacing the rod the size of the opening through the jet is varied, displacement of the rod being effected by a pivotably mounted lever having an eccentric portion which is urged against the base portion of the rod by an actuator coupled to the lever by a cable. The actuator may comprise a laterally and vertically displaceable pedal and air throttle butterfly of the carburettor being actuated by vertical displacement while the rod is actuated by lateral displacement. The actuator may alternatively be a knob mounted on a control panel.

In at least some implementations a carburetor may include a main bore through which a fuel and air mixture is delivered from the carburetor, a fuel metering assembly, a supplemental fuel pump and a valve. The supplemental fuel pump includes a diaphragm that defines a fuel chamber on one side from which fuel may be discharged to at least temporarily increase the amount of fuel discharged from the carburetor and a reference chamber on the other side that is communicated with a reference pressure source. The valve is electrically actuated and moveable between first and second positions to at least substantially prevent communication of the reference pressure source with the supplemental fuel pump diaphragm when the valve is in its second position to thereby inhibit or prevent fuel being discharged from the fuel chamber.

The invention relates to an injection device ( 1 ), designed in particular for injecting fluid into an exhaust tract of an internal combustion engine, having a valve needle ( 14 ), an injection chamber ( 12 ) having at least one injection opening ( 44 ), and a control chamber ( 20 ). The injection device ( 1 ) is designed such that a pressure differential between the injection chamber ( 12 ) and the control chamber ( 20 ) brings about a displacement of the valve needle ( 14 ) between an open position in which a fluid flow through the injection opening ( 44 ) from the injection chamber ( 12 ) is released, and a closed position, in which the injection opening ( 44 ) is closed off. The injection chamber ( 22 ) and the control chamber ( 20 ) are hydraulically connected to an inlet ( 40, 42; 9 ), such that a pressure rise in the inlet ( 40, 42; 9 ) results in a pressure rise in the injection chamber ( 12 ), and a pressure rise in the control chamber ( 20 ) delayed in time relative to the pressure rise in the injection chamber ( 12 ), and said pressure differential brings about a displacement of the valve needle ( 14 ) from the closed position into an open position.
