Abstract
L'invention concerne un poussoir de soupape variable, comprenant une base de poussoir (9) et un support (12). La base de poussoir (9) est d'une structure de cylindre ayant une rainure cylindrique creuse en forme de T disposée sur une partie supérieure de celle-ci, et un manchon de poussoir (14) de structure cylindrique creuse est ajusté sur la base de poussoir (9). Le poussoir comprend en outre une base de tige de poussée de soupape (16) qui est d'une structure cylindrique. Une cavité de levage supplémentaire (20) est formée entre la surface inférieure de la base de tige de poussée de soupape (16) et la base de poussoir (9). Le support (12) est d'une structure cylindrique creuse. La surface supérieure de la base de tige de poussée de soupape (16) s'étend vers l'extérieur le long du bord externe du cylindre pour correspondre à la surface interne du support (12), de telle sorte qu'une cavité de stockage d'huile (17) soit formée entre la surface supérieure de la base de tige de poussée de soupape (16) et la surface interne du support (12). Une cavité de pompage d'huile (11) est formée entre la surface extérieure du support (12), la surface intérieure du manchon de poussoir (14) et la base de poussoir (9). Un ressort de poussoir (19) est disposé dans la cavité de pompage d'huile (11) à l'extérieur de la base de tige de poussée de soupape (16). Le manchon de poussoir (14) est pourvu d'une entrée d'huile (8) reliée à un système d'alimentation en huile, et d'un orifice de retour d'huile (22) connecté à un système de retour d'huile. La surface supérieure de la base de tige de poussée de soupape (16) est reliée à une tige de poussée de soupape (15). Une came (1) est disposée directement sous la base de poussoir (9). Le poussoir de soupape variable peut réaliser une commande de synchronisation et de levée de soupape dans des situations de fonctionnement où un moteur a des vitesses différentes, et présente des coûts faibles, une applicabilité et une stabilité élevées.
