Abstract

Installation comportant, entre le circuit de frein fermé et un point de remplissage, un dispositif de commande qui ouvre momentanément ledit circuit pour refaire le plein. L'amplificateur de freinage 1 est placé entre la pédale 2 et deux paires de frein de roue 3, 3' et 4, 4' des circuits I et II. Ceux-ci sont surveillés par un élément de réglage multiple 5 d'une protection anti-blocage. L'installation comporte en outre un moteur 6, une pompe 7, un accumulateur 8, une soupape de frein 10, un piston d'amplificateur 11, un poussoir de pédale 12, un ressort 13, un poussoir 14, un ressort de rappel 15, une chambre 16, une soupape antiretour 17, deux réservoirs de remplissage 22 et 29, une chambre de pression primaire 24, un maître-cylindre 25, un piston double 26, une chambre de pression secondaire 27, un dispositif de commande 30, une soupape antiretour 35, une soupape de commande 30.Installation comprising, between the closed brake circuit and a filling point, a control device which momentarily opens said circuit to refuel. The brake amplifier 1 is placed between the pedal 2 and two pairs of wheel brakes 3, 3 'and 4, 4' of circuits I and II. These are monitored by a multiple adjustment element 5 of an anti-blocking protection. The installation further comprises a motor 6, a pump 7, an accumulator 8, a brake valve 10, an amplifier piston 11, a pedal pusher 12, a spring 13, a pusher 14, a return spring 15 , a chamber 16, a non-return valve 17, two filling tanks 22 and 29, a primary pressure chamber 24, a master cylinder 25, a double piston 26, a secondary pressure chamber 27, a control device 30, a non-return valve 35, a control valve 30.
