Fuel Pump Nozzle with Manually Operated Switch Lever and Hold-Open Aid

摘要

Disclosed is a fuel pump nozzle for delivering fuel. The pump nozzle includes a manually operated switch lever which is movable between a closed position, in which there is no delivery of fuel, and open positions, in which fuel is delivered. The switch lever is biased by a restoring spring in the direction of the closed position and is moveable in the direction of the open positions by manual force. The pump nozzle further includes a hold-open aid which reduces the manual force required to hold the switch lever in at least one predetermined open position compared to the manual force required to hold the switch lever open in other open positions. The hold-open aid holds the switch lever in the predetermined open position only if manual force is maintained. The hold-open aid releases the switch lever upon removal of the manual force so that the lever can move back to the closed position.
