Title
(EN) HIGH PRESSURE FUEL NOZZLE
(FR) INJECTEUR DE CARBURANT HAUTE PRESSION
Abstract
(EN)
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.
(FR)
La présente invention concerne un injecteur de fluide à arrêt automatique présentant un trajet de fluide primaire, un ensemble d'arrêt de fluide actionné sous vide dans le trajet de fluide, ledit arrêt arrêtant l'écoulement à travers le trajet de fluide lorsque la chambre de pression est soumise à un vide prédéterminé. L'injecteur présente un orifice venturi dans ledit trajet de fluide et est raccordé à un canal sous vide, et un évent sous vide s'étend à l'opposé du canal sous vide, ledit évent sous vide communiquant avec un environnement à faible vide. L'injecteur comprend en outre un canal de fluide séparé dans le trajet de fluide primaire, l'orifice venturi communiquant avec ledit canal de fluide séparé de sorte que l'écoulement de fluide au-delà de l'orifice venturi crée un vide venturi dans le canal sous vide. Le vide évacue le vide à travers l'orifice d'évent lorsque l'orifice d'évent est dans un état ouvert et crée un vide dans l'ensemble d'arrêt de fluide actionné sous vide lorsque ledit orifice d'évent est dans un état fermé.
