ABSTRACT:
A reciprocating fuel pump for an internal combustion engine comprising a body having an outer wall defining a pumping chamber and a pair of generally cylindrical projections in fluid communication with the pumping chamber, the projections defining an intake cavity with an intake check valve therein and a discharge cavity with a discharge check valve therein. Elastomeric tubular conduits within the projections form the intake and discharge cavities and are of a flexibility sufficient to provide a collapsing and an expansion of the conduit walls upon relatively small pressure variations resulting from the suction and discharge strokes of the diaphragm. The elastomeric conduits thereby provide pulsating chambers to smooth out the flow of fuel and thereby increase the fuel flow through the fuel pump.
