Abstract
Improved fuel feed pump, characterized essentially by the fact that its impeller rod comprises, at one of its ends, a piece configured as a button, with a central notch surrounding to achieve the strengthening of the membrane, through a a drill provided for this purpose, the button ending according to an advantageously convex spike on which a piston-cup supports containing a taper coil spring, extended between the bottom thereof and the cover of the body that houses the component parts of the assembly, the cup-piston being able to move, axially, integrally with the button, membrane and driving rod, with a communication channel between the rear part of the piston-piston and the outlet, assuring the automatic regulation of the fuel flow and the stroke of the piston as a function of the accumulated pressure at the outlet and the tarado of the spring.
