Abstract
A tank intended for an electrohydraulic braking system comprises, according to the present invention, a first chamber () for the supply of a primary hydraulic circuit of a master cylinder with brake fluid, a second chamber () for the supply of a secondary hydraulic circuit of the master cylinder (not shown) with brake fluid, a third chamber () for the supply of a hydraulic pump with brake fluid, and a fourth chamber (), a measuring one, which accommodates a detection device, indicating when the brake-fluid level inside the tank is too low. The tank has a flow path for the interconnection of the first chamber (), the second chamber () and the third chamber () when the hydraulic-fluid level is higher than a safety level, and for the fluid-tight separation of said chambers when the hydraulic-fluid level is lower than the safety level.
