Hydraulic circuit comprising a piston for lock prevention of vehicle brakes.

摘要

The antilock device for vehicles with hydraulic brakes comprises a double-acting piston (9) sliding in a cylinder (8) placed in the pipe system (4, 15) supplying at least one of the wheel cylinders (17). An actuator (23) can move the piston (9), cut off the hydraulic link with the master cylinder (1) and increase the volume available to the brake fluid on the side of the receiving cylinder (17) when a tendency for the wheel to lock occurs. The pressure variation is continuous. <IMAGE>
