Abstract

Maître-cylindre hydraulique comportant un boîtier à l'intérieur duquel est défini un alésage. Un piston disposé dans l'alésage sépare ce dernier en une chambre de compression et une chambre d'alimentation. Le piston comporte un épaulement radial coopérant avec une bague en matériau élastomère formant soupape pour contrôler la communication entre la chambre d'alimentation et la chambre de compression. La bague comporte une lèvre qui coopère avec l'épaulement pour constituer un clapet anti-retour situé entre la chambre de compression et la chambre d'alimentation. Application aux systèmes de freinage de véhicules.
