Slip-controlled hydraulic braking system for vehicle - has ASR valve between main brake cylinder and low pressure store allowing pump to pass fluid to wheel brake

摘要

The braking system has a two/two way ASR valve (18) switched from open to closed by pressure in the pressure line (16) against pressure in the main brake cylinder. This ASR valve is shunted by an electromagnetic two/two way value that blocks the shunt time in its basic position. An overpressure valve (14) shunts an isolating valve in the brake line and limits the pressure in the wheel-brake side of the brake line. pressure side of a pump is connected by the pressure line to bhe brake line between the isolating valve and an inlet valve. An electromagnetic outlet valve (9) lies in a return line (10) between wheel brake (6) and a low pressure store (11). USE/ADVANTAGE - Short travel distances brake pedal. Hydraulic braking circuit is blocked hydraulically when brake pedal is not depressed.
