    Abstract: The invention relates to a filling valve for dispensing a fluid, comprising an inlet opening for connecting to a fluid supply line, an outlet end (12) which lies opposite the inlet opening, a main valve for controlling the flow of the fluid through the filling valve, and a leakage protection valve (13) which is arranged downstream of the main valve, comprising a valve seat (14) and a valve body (15, 16) which can be moved into a closed position in an upstream direction. According to the invention, the valve body (15, 16) has a first sub-body (15) and a second sub-body (16) which is designed to be movable relative to the first sub-body, wherein a first fluid path (17) can be released by a movement of the first sub-body (15) in a downstream direction relative to the valve seat (14), and a second fluid path (18) can be released by a movement of the second sub-body (16) in a downstream direction relative to the first sub-body (15). By virtue of the two-part valve body according to the invention, the flow of fluid through the filling valve can be optimized and the back pressure accumulating in front of the leakage protection valve can be reduced.

    Abstract: A vapor-recovery-activated auto-shutoff nozzle comprises a manually operable trigger that permits selective operation of a normally closed valve between a valve-closed configuration and a valve-open configuration. Linkage arms connect the trigger and the valve, and are re-configurable between an enabled configuration and a disabled configuration. In the enabled configuration, the trigger and the valve are operatively connected such that the rest position of the trigger corresponds to the valve being closed, and the in-use position of the manually operable trigger corresponds to the valve being open. In the disabled configuration, the manually operable trigger is precluded from controlling the valve. A deactivation mechanism is for re-configuring the linkage means from the enabled configuration to the disabled configuration, in response to a condition of the fluid in a vapor recovery conduit of the nozzle, thereby precluding the valve from being controlled until the linkage arms are reset to the enabled configuration.

    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).
