Title (EN) HYDRAULIC CONTINUOUSLY VARIABLE TRANSMISSION AND POWER TRANSMISSION DEVICE
(FR) TRANSMISSION HYDRAULIQUE A CHANGEMENT DE VITESSES CONTINU ET DISPOSITIF DE TRANSMISSION D'ENERGIE
Abstract: front page image
(EN)In a hydraulic continuously variable transmission, an oil path connecting a valve hole, a first and a second plunger hole is formed in a cylinder block. The oil path has a confluent portion for converging the valve hole with the first and the second plunger hole. A distributing valve which stops flow-in of hydraulic fluid into the plunger hole or flow-out of the hydraulic fluid from the plunger hole has a land portion located at both sides of the confluent portion and a shaft portion opposed to the confluent portion. The land portion has a cross section area set almost identical to the cross section area of the valve hole and the shaft portion has a cross section area set smaller than the cross section area of the valve hole.
(FR)La présente invention concerne une transmission hydraulique à changement de vitesses continu comportant un passage d'huile débouchant sur un orifice de vanne, avec deux trous de piston dans le bloc-cylindres. Le passage d'huile présente une confluence permettant la convergence de l'orifice de vanne avec les deux trous de piston. Une vanne de distribution arrêtant l'arrivée de fluide hydraulique dans le trou de piston ou la sortie du fluide hydraulique du trou de piston, comporte un relief des deux côtés de la confluence, et une tige opposée à la confluence. Le plan en coupe du relief est sensiblement identique au plan en coupe de l'orifice de vanne, le plan en coupe de la tige étant plus petit que celui de l'orifice de vanne.
