Title
(EN) THROTTLE FOR ELECTRONIC FUEL INJECTION
(FR) PAPILLON POUR INJECTION DE CARBURANT ÉLECTRONIQUE

Abstract
(EN)
A throttle for electronic fuel injection comprises: a throttle body (1); a first throttle hole (2) and a second throttle hole (3) provided in the throttle body, a first throttle shaft (4) and a second throttle shaft (5) being respectively mounted in the first throttle hole and the second throttle hole, a first throttle piece (6) and a second throttle piece (7) being respectively mounted on the first throttle shaft and the second throttle shaft, a first gear (8) and a second gear (9) being respectively mounted on lower ends of the first throttle shaft and the second throttle shaft, and a first throttle rocker arm (15A) and a first return torsion spring (16A), and a second throttle rocker arm (15B) and a second return torsion spring (16B) being respectively mounted on upper ends of the first throttle shaft and the second throttle shaft; and a main gear (10), the first gear and the second gear separately engaging with the main gear, a protruding rod (11) being provided on the main gear, and the protruding rod being connected to a motor (14) by means of a motor rocker arm (13). Minimum flow rates of the two throttle holes can be adjusted separately, thereby ensuring consistency between low flow rates of two cavities.

L'invention concerne un papillon pour une injection de carburant électronique, lequel papillon comprend : un corps de papillon (1) ; un premier trou de papillon (2) et un second trou de papillon (3) réalisés dans le corps de papillon, un premier axe de papillon (4) et un second axe de papillon (5) étant respectivement montés dans le premier trou de papillon et le second trou de papillon, un premier élément de papillon (6) et un second élément de papillon (7) étant respectivement montés sur le premier axe de papillon et le second axe de papillon, un premier engrenage (8) et un second engrenage (9) étant respectivement montés sur des extrémités inférieures du premier axe de papillon et du second axe de papillon, et un premier levier oscillant de papillon (15A) et un premier ressort de torsion de rappel (16A), et un second levier oscillant de papillon (15B) et un second ressort de torsion de rappel (16B) étant respectivement montés sur des extrémités supérieures du premier axe de papillon et du second axe de papillon ; et un engrenage principal (10), le premier engrenage et le second engrenage s'engrenant de façon séparée avec l'engrenage principal, une tige faisant saillie (11) étant disposée sur l'engrenage principal, et la tige faisant saillie étant reliée à un moteur (14) au moyen d'un levier oscillant de moteur (13). Des débits d'écoulement minimum des deux trous de papillon peuvent être ajustés séparément, assurant ainsi une cohérence entre de faibles débits d'écoulement de deux cavités.
