Abstract

Una válvula de inyección de combustible y un miembro de retención para una válvula de inyección de combustibleque retiene en un miembro (1) de conducto de admisión exclusivamente una sola válvula (10) de inyección decombustible 5 que tiene una porción (11) de inyección de combustible en un extremo de la misma insertada en unorificio (4) de montaje proporcionado en el miembro (1) de conducto de admisión, y comprende una porción (21) detapa, una porción (27) de junta de combustible y una porción (26) de soporte de montaje que están formadasintegralmente de una resina sintética mediante moldeo para conectar integralmente la porción (27) de junta decombustible y la porción (26) de soporte de montaje a la porción (21) de tapa que está ajustada con estanqueidad alíquidos en una periferia exterior de una porción (12) de entrada de combustible en el otro extremo de la válvula (10)de inyección de combustible, estando conectada la porción (26) de soporte de montaje en el miembro (1) deconducto de admisión, teniendo la porción (27) de junta de combustible un interior que comunica con un interior de laporción (21) de tapa, donde una superficie periférica interior de la porción (21) de tapa se forma mediante una superficie (22) de ajustecilíndrica; un miembro (17) de sellado se ajusta en una periferia exterior de la porción (12) de entrada de combustible y laporción (12) de entrada de combustible se ajusta en la superficie (22) de ajuste y el miembro (17) de sellado está encontacto cercano con la superficie (22) de ajuste; dicho miembro (20) de retención es un solo miembro de retención para retener dicha sola válvula (10) de inyecciónde combustible y tiene una parte (28') de conexión que se conecta entre la porción (21) de tapa y la porción (26) desoporte de montaje; y la parte (28') de conexión está conectada a la porción (21) de tapa en una región de unaperiferia interior de la porción (21) de tapa, que está lejos en una dirección axial de la superficie (22) de ajuste a laporción (12) de entrada de combustible; caracterizado por que la parte (28') de conexión es más delgada que el espesor de la pared de la porción (21) de tapa para hacer la rigidezde dicha parte (28') de conexión inferior que la rigidez de la porción (21) de tapa y por que la porción (26) de soportede montaje está configurada como un par de porciones (26, 26) de soporte de montaje, donde el par de porciones (26, 26) de soporte de montaje y la porción (27) de junta de combustible se disponen deuna manera dispersa alrededor de la porción (21) de tapa.A fuel injection valve and a check member for a fuel injection valve that retains in an intake duct member (1) exclusively a single fuel injection valve (10) 5 having a fuel injection portion (11) fuel at one end thereof inserted into a mounting hole (4) provided in the intake duct member (1), and comprises a cover portion (21), a fuel seal portion (27) and a portion (26) ) of mounting bracket which are integrally formed of a synthetic resin by molding to integrally connect the fuel seal portion (27) and the mounting bracket portion (26) to the cap portion (21) which is tightly sealed to liquids in an outer periphery of a fuel inlet portion (12) at the other end of the fuel injection valve (10), the mounting bracket portion (26) being connected to the intake duct member (1), the fuel seal portion (27) having an interior communicating with an interior of the cap portion (21), wherein an inner peripheral surface of the cap portion (21) is formed by a cylindrical setting surface (22); a sealing member (17) is fitted on an outer periphery of the fuel inlet portion (12) and the fuel inlet portion (12) is fitted on the fitting surface (22) and the sealing member (17) it is in close contact with the setting surface (22); said retention member (20) is a single retention member for retaining said single fuel injection valve (10) and has a connecting part (28 ') that connects between the cap portion (21) and the portion (26) ) mounting bracket; and the connecting part (28 ') is connected to the cap portion (21) in a region of an inner periphery of the cap portion (21), which is away in an axial direction from the fit surface (22) the fuel inlet portion (12); characterized in that the connecting part (28 ') is thinner than the wall thickness of the cover portion (21) to make the stiffness of said connecting part (28') lower than the stiffness of the portion (21) cap and because the mounting bracket portion (26) is configured as a pair of mounting bracket portions (26, 26), where the pair of mounting bracket portions (26, 26) and the portion (27) The fuel gasket is arranged in a scattered manner around the cap portion (21).
