Post nasal neutralization phenomena in Tswana - more on *N… constraints

A compact closed nozzle assembly for a fuel injector is provided which reduces the total length of the injector, minimizes the trapped volume of fuel and, thus, the response time of the injector and eliminates a high pressure joint in the injector body. The compact closed nozzle assembly of the injector includes a nozzle valve element positioned in an injector cavity adjacent injector orifices and operable to be placed in an open position in which fuel may flow a fuel transfer circuit through the injector orifices into the combustion chamber, and a closed position in which fuel flow through the injector orifice is blocked. A nozzle spring, which is shorter and larger in diameter than conventional nozzle springs, biases the nozzle valve element into the closed position. A stationary housing is mounted adjacent the nozzle valve element so that a portion of the housing is positioned within an inner radial extent of the nozzle spring while a portion of the fuel transfer circuit extends through the stationary housing within the inner radial extent of the spring. A check valve may be positioned in a check valve cavity formed in the stationary housing within the inner radial extent of the nozzle spring for preventing the flow of fuel from the metering chamber into a supply passage. A button device having a plurality of legs is positioned adjacent the stationary housing in an overlapping manner for operatively connecting the nozzle spring to the nozzle valve element.
