    摘要: A plunger valve nozzle has a nozzle body with a constant diameter bore extending therethrough, one end of which is open to receive fluid under pressure and has a hollow plunger extending thereinto with a direct acting piston portion slidably fitting the bore and exposed to the fluid pressure through the open end of the bore, there being orifices connecting the interior of the plunger to the periphery of the piston portion which are uncovered by the bore when the fluid pressure is sufficient to move the plunger further inwardly of the bore a predetermined distance, which movement is opposed by a spring connected to the plunger and reacting against the nozzle body.

    摘要: An orifice plunger valve fuel injector is provided with a nozzle body having a bore extending from one end thereof, a plunger valve being slidably mounted and closely fitted within the bore of the nozzle body, the end of the plunger valve adjacent said one end of said nozzle body being provided with radially extending spray tip holes therein which are supplied with pressurized fuel through an axial passage in the plunger valve in communication at one end with the spray tip holes and at its other end, intermediate the ends of the plunger valve, with at least one radial passage in communication with an inlet fuel passage means in the nozzle body supplied with fuel under pressure through a one-way valve from a source of fuel under pressure, a retractor spring being positioned in the nozzle body and operatively connected with the plunger valve to normally bias the plunger valve into a retracted position within the bore of the nozzle body whereby the spray tip holes are closed off by the bore wall of the nozzle body, when the pressure of fuel in said fuel passage is less than the pressure required acting on the differential area of the plunger valve to effect its axial displacement in the bore of the nozzle body, against the force of the retractor spring, to a position where the spray tip holes are uncovered to effect fuel injection. The spray holes will be uncovered only sufficiently to maintain the predetermined fuel injection pressure at the orifices formed by the spray tip holes in the plunger valve and the lower end of the nozzle body.
