Abstract

Maîtres-cylindres à deux pistons, par exemple du type en tandem. Lorsque la pression croît dans la chambre primaire 29, en vue du serrage d'un jeu de freins, l'accroissement de pression dans la chambre secondaire 33 est retardé par l'action d'un piston de commande 16 qui emprisonne le fluide hydraulique dans une chambre de commande 45. Une vanne comprenant une bille 47, le piston de commande 16 et un ressort de commande 42 commande la pression dans la chambre de commande de manière telle que, lorsque la pression dans la chambre primaire atteint un niveau déterminé, la pression de la chambre de commande commence à diminuer et finit par devenir égale à la pression dans la chambre secondaire Le maître-cylindre est destiné à être utilisé dans un système comprenant des freins à tambour reliés à la chambre primaire et des freins à disque reliés à la chambre secondaire.
