Abstract:
1. A fuel pump nozzle, with an inlet ( 2 ), a discharge pipe ( 3 ), a main valve for controlling the stream of liquid between the inlet ( 2 ) and discharge pipe ( 3 ), a switching lever ( 4 ) for actuating the main valve, a first automatic safety shut-off which moves the main valve into a closed position if the liquid level in a tank to be filled reaches a filling level sensor arranged in the region of the discharge pipe ( 3 ), a second automatic safety shut-off which moves the main valve into the closed position if a liquid pressure at the inlet ( 2 ) drops below a minimum value, and a mechanism ( 13 ) for prestressing the main valve into the closed position, said mechanism bringing about a variable opening cross section of the main valve depending on the liquid pressure at the inlet ( 2 ), wherein the main valve comprises a valve seat having an axis and the main valve is pressed into the closed position in a tilted manner with respect to the axial direction of said valve seat under the action of the mechanism for prestressing the main valve into the closed position in a full hose mode such that a tightness of said main valve is reduced.
