Abstract[English]
The present application proposes fuel rail (1000) that comprises a tube (10) with a tube hole (11) and a plurality of injector cups (20) in fluid flow communication with the tube hole (11) via a respective plurality of T-shaped cross bores that include a first bore (B1) and a second bore (B2). The first bore (B1) extends from the tube hole (11) towards a front face (22) of a respective injector cup (20), said front face (22) being distal to the tube hole (11) with regard to a central axis of the first bore (B1). The second bore (B2) is arranged to provide fluid flow communication from the first bore (B1) to an inner volume (21) of the injector cup (20). The first bore (B1) is provided with a plug (60) at a distal end of the first bore (B1) with regard to the tube hole (11). A distal end of the first bore (B1) is provided with a plug housing (61) such that, radial to a plug axis (Ap), the plug housing (61) has a greater diameter when compared to a diameter of the first bore (B1). The plug housing (61) is provided with a wedge (70) that is arranged for pushing and biasing the plug (60) towards the tube hole (11). The plug housing (61) is further provided with a couple of wedge bores (71) for receiving and hosting the wedge (70) across the plug axis (Ap).[French]
La présente demande propose une rampe à carburant (1000) qui comprend un tube (10) pourvu d'un trou de tube (11) et une pluralité de coupelles d'injecteur (20) en communication d'écoulement de fluide avec le trou de tube (11) par l'intermédiaire d'une pluralité respective d'orifices transversaux en T qui comprennent un premier orifice (B1) et un second orifice (B2). Le premier orifice (B1) s'étend à partir du trou de tube (11) vers une face avant (22) d'une coupelle d'injecteur respective (20), ladite face avant (22) étant distale du trou de tube (11) par rapport à un axe central du premier orifice (B1). Le second orifice (B2) est agencé pour fournir une communication d'écoulement de fluide du premier orifice (B1) à un volume interne (21) de la coupelle d'injecteur (20). Le premier orifice (B1) est pourvu d'un bouchon (60) à une extrémité distale du premier orifice (B1) par rapport au trou de tube (11). Une extrémité distale du premier orifice (B1) est pourvue d'un boîtier de bouchon (61) de telle sorte que, radialement par rapport à un axe de bouchon (Ap), le boîtier de bouchon (61) a un diamètre supérieur lorsqu'il est comparé à un diamètre du premier orifice (B1). Le boîtier de bouchon (61) est pourvu d'un coin (70) qui est agencé pour pousser et solliciter le bouchon (60) en direction du trou de tube (11). Le boîtier de bouchon (61) est en outre pourvu d'une paire d'orifices de coin (71) destinés à recevoir et loger le coin (70) à travers l'axe de bouchon (Ap).
