Title (EN) RESERVOIR FILLING APPARATUS
(FR) APPAREIL DE REMPLISSAGE D"UN RESERVOIR
Abstract: front page image
(EN)A hydraulic circuit (10) has a fluid supply source (12) to a work element, such as a control valve (14) for a work implement, connected by a first fluid pathway (18). A second work element (16), such as a master cylinder reservoir of a brake system, has a fluid level (36) which is desirably maintained against leakage in the system to prevent problems in using the brake system. The master cylinder reservoir (16) is associated with the hydraulic circuit (10) by apparatus (38, 42) which initiate pressure conditions in fluid pathways (22, 24) positioned in fluid communication with the master cylinder reservoir (16) to maintain the desired fluid level. The pressure conditions create a pressure differential which initiates or induces a fluid flow from the hydraulic circuit (10) to the master cylinder reservoir (16) to maintain the reservoir fluid level and substantially prevent undesirable braking characteristics which can result from an improper fluid level.
(FR)Un circuit hydraulique (10) possede une source d"alimentation en fluide (12) qui amene le fluide vers element de travail, tel qu"une soupape de commande (14) pour un outil de travail, connecte par un premier passage de fluide (18). Un second element de travail (16) tel qu"un reservoir d"un maitre cylindre d"un systeme de frein, possede un niveau de fluide (36) qui est protege contre les fuites dans le systeme pour eviter les problemes de fonctionnement du systeme de freinage. Le reservoir du maitre cylindre (16) est associe au circuit hydraulique (10) par un appareil (38, 42) qui etablit des conditions de pression dans les passages de fluide (22, 24) en communication fluide avec le reservoir (16) du maitre cylindre pour maintenir le niveau de fluide desire. Des conditions de pression creent une pression differentielle qui declenche ou induit un ecoulement de fluide depuis le circuit hydraulique (10) vers le reservoir du maitre cylindre (16) pour maintenir le niveau de fluide du reservoir et eviter des caracteristiques de freinage indesirables qui peuvent etre le resultat d"un niveau non approprie du fluide.
