A fuel receiver assembly, that permits replacement of a worn fuel receiver without draining the fuel tank, includes a check valve receptacle having a male-pipe-threaded nipple which engages the female-threaded pipe coupling of the fuel tank. The check valve receptacle has a spring-biased, normally closed check valve that prevents fuel from escaping from the fuel tank. Fuel pressure from the refueling pump opens the normally-closed check valve. The check valve receptacle is designed to be a relatively permanent installation in the fuel tank, having ultra-low-wear components. The check valve receptacle also has a female-threaded socket that is coaxial with the male-pipe-threaded nipple. A specially-designed male-threaded fuel receiver engages the female-threaded socket. Sealing between the check valve receptacle and the replaceable fuel receiver is accomplished by an O-ring seal installed on the fuel receiver.
L'invention concerne un ensemble prise de carburant qui permet de remplacer une prise de carburant abîmée sans vider le réservoir de carburant. Cet ensemble comprend un réceptacle de clapet anti-retour muni d'un mamelon fileté de tuyau mâle qui raccorde le tuyau fileté femelle à la pièce de raccord du réservoir de carburant. Le réceptacle de clapet anti-retour comporte un clapet anti-retour normalement fermé, sollicité par ressort, qui empêche le carburant de fuir du réservoir de carburant. La pression de carburant de la pompe de remplissage entraîne l'ouverture du clapet anti-retour normalement fermé. Le réceptacle du clapet anti-retour est conçu comme une installation relativement permanente dans le réservoir de carburant, dotée de composants à très faible usure. De plus, le réceptacle de clapet anti-retour comprend une douille femelle filetée qui est coaxiale au mamelon fileté de tuyau mâle. Une prise de carburant filetée mâle spécialement conçue s'emboîte dans la douille filetée femelle. Un joint torique monté sur la prise de carburant assure l'étanchéité entre le réceptacle de clapet anti-retour et la prise de carburant remplaçable.
