Abstract
The subject of the present invention is a liquid dispenser intended for vehicles and a method implemented during the operation of such a liquid dispenser. The liquid dispenser for a vehicle includes a liquid dispensing circuit (2) connected at one end to a liquid reservoir and at the other end to a flexible hose (3) connected to a gun (4) for dispensing the liquid from a reservoir of the vehicle, the flexible hose (3) having two substantially coaxial ducts (5, 6) including a first duct (5) for transferring the liquid from the liquid dispensing circuit (2) to the gun (4) during the delivery of the liquid from the reservoir of the vehicle, and a second duct (6) extending along the first duct (5). The liquid dispenser includes a heating system (7) intended to generate a flow of hot air through the second duct (6) of the flexible hose (3) so as to heat the liquid inside the first duct (5) of the flexible hose (3).
