<p>In a skid-controlled brake system including a diagonal division of the brake circuits (I and II), the wheel brakes (31 to 34), through main brake lines (62, 63) and branch lines (47 to 50), are in communication with the master cylinder (2) of the brake pressure generator (1), with inlet valves (24, 25 and 29, 30, respectively), open in de-energized position, being provided in the branch lines. Moreover, in-flow lines (45, 46) provided with check valves (38, 39) are couupled to the main brake lines (62, 63), through which, in the event of a locking tendency of the vehicle wheels, pressure fluid is delivered by two hydropumps (21, 26) into the brake circuits (I, II) causing the pistons (6, 7) of the master cylinder (2) to be restored against the pedal force (F) and the central control valves (10, 11) located in pistons (6, 7) to be opened thereby enabling pressure fluid to flow off into the tank (20). The wheel brakes ( 31 to 34), through outlet valves (22, 23 and 35, 36, respectively), closed in de-energized condition, are in communication with a return line (37) also connected to which is the intake line (61) of the two pumps (21, 26).</p> |
