A duty-cycle type electromagnetic injector assembly has a valve and cooperating valve seat with the valve being positioned away from or against the valve seat depending upon whether an associated electrical coil is energized; a housing generally contains the valve and valve seat, a locator or guide closely confines the valve permitting the valve to be freely moved toward and away from the valve seat while constraining movement of the valve in other directions; the locator or guide is in turn prevented from movement by a retainer operatively connected to the housing and frictionally engaging the locator or guide.

Electromagnetically actuatable fluid valve

An accelerating pump system is shown having a chamber into which fuel from a fuel reservoir of fuel bowl is drawn and then, when and as required, ejected, as by a displaceable diaphragm within said chamber, into a passage leading to accelerating fuel nozzle structure for discharge into the induction passage of the related carburetor or fuel metering means; a vent passage serves to communicate between the fuel reservoir and the chamber as to enable a portion of the fuel within the chamber to be returned to the fuel reservoir when the diaphragm is being displaced for ejecting fuel into the said passage; a thermostatic valve serves to preclude such communication between the fuel reservoir and the chamber except when the fuel temperature (employed as an indicia of engine and indirectly ambient temperature) within the chamber attains a predetermined relatively elevated temperature.
