摘要： A fuel injection nozzle has a tubular body adapted to receive fuel, a tubular seat member mounted to the body, the seat member having an opening for discharging fuel and a valve seat surrounding the opening, a poppet valve member engageable with the valve seat to interrupt fuel flow through the opening, and an extension spring anchored to the body and to the valve member and biasing the valve member to engage the valve seat. The extension spring is a helically coiled spring with each coil lying close to the adjacent coils and with the coils at one end overlying an end of the body to anchor the spring to the body and to cause fuel flowing through the nozzle to pass between the coils of the spring; the spring thereby acts as a filter for fuel to be discharged by the nozzle. The seat member is axially movable relative to the body to adjust the length of the spring and thus the bias on the valve member whereby the desired valve-opening pressure differential may be established. The body is adapted to receive fuel through a restriction member that limits fuel flow through the opening. The valve member has a shank with a valve element at one end and a head at the other end, the shank being formed as a pin and the valve element as a ball that is welded to the pin.

摘要： An electromagnetic fuel injector has an orificed fuel director plate, mounted downstream of a solenoid actuated valve and an associated main orifice passage opened and closed by the valve, to receive fuel when the valve is pulled to an open position from its associated valve seat for controlling and directing flow from the injector. The upper surface of the orifice director plate is provided with a fuel distributing channel system terminating in separate pairs of cooperating injection orifices that are disposed adjacent to one another to direct adjacent jets of fuel which partially intersect one another producing discrete cones of atomized fuel accurately onto separate fuel intake valves of a piston cylinder of an internal combustion engine.
