An automatic shut-off fluid nozzle having a primary fluid path, a vacuum-actuated fluid shut-off assembly in the fluid path, said shut-off shutting off flow through the fluid path when the pressure chamber is subjected to a predetermined vacuum. The nozzle having a venturi port in said fluid path and connected to a vacuum channel, and a vacuum vent extending away from the vacuum channel, said vacuum vent communicating with a low vacuum environment. The nozzle further having a segregated fluid channel in the primary fluid path, the venturi port communicating with said segregated fluid channel, such that the flow of fluid past the venturi port creates a venturi vacuum in the vacuum channel. The vacuum exhausts the vacuum through the vent port when the vent port is in an open condition, and creates a vacuum in the vacuum-actuated fluid shut-off assembly when said vent port is in a closed condition.

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.
