AI Technical Summary

Technical Problem

Existing distribution nozzles have a complex structure when adjusting flow rate, requiring intervention from automatic shut-off devices, resulting in complex construction and difficult maintenance.

Method used

An adjustable flow restrictor, configured separately from the main valve, interacts with the tank signal element via an actuator to selectively adjust either the first maximum volumetric flow rate or the second maximum volumetric flow rate, simplifying the construction of the distribution nozzle and improving functional reliability.

Benefits of technology

The structure of the dispensing nozzle has been simplified, reducing maintenance difficulty and improving the flexibility and reliability of flow rate adjustment, thus adapting to the rapid filling needs of different tank capacities.

Abstract

A dispensing nozzle for dispensing a fluid into a tank of a motor vehicle, comprising the following features: - the dispensing nozzle comprises a passage for the passage of the fluid, wherein a main valve is arranged in the passage, the main valve being movable between a closed position and an open position to control the flow of fluid, - the dispensing nozzle comprises a first maximum volumetric flow rate and a second maximum volumetric flow rate, wherein the second maximum volumetric flow rate is greater than the first maximum volumetric flow rate, according to the invention, such that the dispensing nozzle comprises an adjustable flow restrictor arranged downstream of the main valve and configured to selectively restrict the flow of fluid to the first maximum volumetric flow rate or to the second maximum volumetric flow rate. The dispensing nozzle further comprises actuating means configured for interacting with a signal element equipped to the tank of the motor vehicle and for selectively adjusting the flow restrictor to the first maximum volumetric flow rate or to the second maximum volumetric flow rate.
