Abstract
La présente invention a pour objet un dispositif de commande hydraulique comportant un piston dont une portion est montée coulissante dans l'alésage d'un cylindre alors que sa portion restante fait saillie par rapport au cylindre et peut exercer sur un organe une poussée fonction de la pression dans le cylindre, avec un déplacement faible du piston, un joint élastique interposé entre le cylindre et le piston assurant d'une part l'étanchéité et d'autre part un effet de rappel lors de la chute de la pression dans le cylindre, une bague de guidage du piston étant montée dans un dégagement cylindre, à l'extérieur du joint élastique d'étanchéité. Selon l'invention, la bague 7 est logée dans le dégagement 8 du cylindre avec un jeu radial a suffisant pour lui permettre de coulisser librement dans ce cylindre, quelles que soient les conditions thermiques d'utilisation, et avec un jeu ou une liberté de coulissement axial b au moins égal à la course de rappel r du piston sous l'action du joint élastique d'étanchéité 6, bague 7 étant ajustée sans jeu sur le piston 1.
