Title (EN) HYDRAULIC CONTROL UNIT WITH FLUID COMPENSATOR TO ACCOMMODATE TRAVEL OF MASTER CYLINDER PISTON
(FR) UNITE DE COMMANDE HYDRAULIQUE AVEC COMPENSATEUR DE LIQUIDE SERVANT A FACILITER LA COURSE DU PISTON DU MAITRE-CYLINDRE
Abstract: front page image
(EN)A fluid compensator (100, 225, 325) is provided in a hydraulic control unit (18, 218, 318) of vehicular brake system (10, 200). The fluid compensator permits additional displacement of a master cylinder piston during anti-lock braking events only by storing fluid in the hydraulic control unit (18, 218, 318). The additional displacement moves a seal mounted on the master cylinder piston away from a compensator port orifice, thereby preventing repeated 'nibbling' of the seal which can cause premature seal failure.
(FR)L'invention concerne un compensateur (100, 225, 325) de liquide destiné à une unité de commande (18, 218, 318) hydraulique d'un système (10, 200) de freins dans un véhicule. Le compensateur de liquide permet au piston du maître-cylindre de prolonger sa course lors du freinage avec antiblocage uniquement par l'accumulation du liquide dans l'unité de commande (18, 218, 318) hydraulique. Le prolongement de la course du piston du maître-cylindre éloigne le joint monté sur ledit piston de l'orifice du compensateur et empêche ainsi le 'grignotage' répété de joint qui risque de provoquer la rupture précoce dudit joint.
