ABSTRACT:
A fuel injection nozzle for engines or the like, including a nozzle barrel and device for delivering fuel to the interior of the barrel. A fuel delivery port is disposed on one end of the barrel and a poppet valve seat is located on the end of the barrel concentric with the port. A poppet valve is seatable against the valve seat to close the port and a valve stem extends through the port into the barrel and has the poppet valve mounted on one end. The port serves as a guide for the stem for reciprocating movement of the stem within the barrel and there are provided a plurality of angularly spaced, longitudinal grooves in at least the valve stem. The grooves are dimensioned so as to extend past the valve seat when the poppet valve is open to provide plural fuel conduits for the flow of fuel from the barrel into a combustion chamber or the like and to be sealed by the valve and the valve seat when the valve is closed to prevent exposure of fuel therein to gases of combustion to thereby prevent vaporization of such fuel and the resultant substantial hydrocarbon emissions.
