Method and system for refuelling
First Claim
1. Method for spill-free refueling, the method comprising the steps of:
- establishing a liquid-tight connection between a nozzle of a refueling gun for fuel dispensing and a coupling piece of a fuel receiving object, fuel being provided through the fuel receiving object to a fuel container;
detecting a predetermined fuel-fill level in the fuel container;
endautomatically interrupting the fuel flow when fuel is detected at said level,wherein a level detection signaling configuration for detecting the predetermined fuel level in the fuel container is established by moving the gun (1) into position for establishment of the liquid-tight connection, wherein complete and secure connection between the nozzle and the coupling piece is detected by means of the level detection signaling configuration, said configuration being fully established when said connection is completed.

Abstract
Method for spill free refuelling includes establishing a liquid tight connection between a refuelling gun nozzle for fuel dispensing and a coupling piece of the fuel receiving object (6), through which fuel is provided to a fuel container (7), detecting a predetermined fuel level (8′) and automatically interrupting the fuel flow when said level is detected. A level detection signalling configuration is established by moving the gun into position for establishment of the liquid-tight connection. The invention further relates to a system for spill free refuelling, a method and a device for detecting a predetermined liquid fuel level and a fuel pipe arrangement.

21. System for spill-free refueling, comprising:
-
means for establishing a liquid-tight connection between a nozzle of a refueling gun for fuel dispensing and a coupling piece of a fuel receiving object, through which fuel is intended to be provided to a fuel container of said object; and means for detecting a predetermined fuel-fill level in the fuel container and for automatically interrupting the fuel flow when fuel is detected at said level, wherein a level detection signaling configuration for detecting the predetermined fuel level in the fuel container is configured to be established by means of moving said gun (1) into position for establishment of the liquid-tight connection, and means (28, 44) for detecting complete and secure connection between the nozzle and the coupling piece by means of the level detection signaling configuration, said configuration being fully established when said connection is completed. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46)
