ABSTRACT:
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.
