Title (EN) FUEL PUMP
(FR) POMPE À CARBURANT
Abstract: front page image
(EN) The fuel pump (10) further comprises a mechanical regulating valve (42) arranged in the pump body (14, 16) and adapted to modulate, in use, the pressure in a high pressure space so that, said pressure matches the engine demand, said modulation requiring adjustment of the inlet (16, 32) fuel quantity, adjustment of the volume of the high pressure space wherein is stored the pressurized fuel and, control of a return fluid communication (10, F3) enabling fuel to exit the high pressure reservoir.
(FR) La présente invention concerne une pompe à carburant (10) qui comprend en outre une soupape de régulation mécanique (42) disposée dans le corps de pompe (14, 16) et conçue pour moduler, lors de l'utilisation, la pression dans un espace à haute pression de sorte que ladite pression correspond à la demande du moteur, ladite modulation nécessitant un réglage de la quantité de carburant d'entrée (16, 32), un réglage du volume de l'espace à haute pression dans lequel le carburant sous pression est stocké et une commande d'une communication de fluide de retour (10, F3) permettant au carburant de sortir du réservoir à haute pression.
