摘要： An anti-skid braking control system for use on a motor vehicle having first and second wheels includes first and second wheel cylinders for braking the first and second wheels, respectively, with a braking medium pressure transmitted from a master cylinder, first and second solenoid-operated valves disposed in pipes interconnecting the master cylinder and the first and second wheel cylinders, respectively, for selectively providing communication between the master cylinder and the first and second wheel cylinders through the pipes, and first and second pumps connected to the pipes, respectively, for delivering a braking medium from portions of the pipes downstream of the valves to portions of the pipes upstream of the valves. The first and second pumps comprise a common housing, a common plunger slidably disposed in the common housing and reciprocally movable therein, and first and second pressure varying chambers defined by the plunger independently of each other and having respective volumes variable in response to reciprocating movement of the common plunger, the first and second pressure varying chambers having inlet ports, respectively, connected directly to the downstream portions of the pipes. When the anti-skid braking control system operates in an anti-skid braking control mode, the common plunger is reciprocally moved to enable the first and the second pumps to reduce the braking medium pressures in the first and second wheel cylinders independently of each other.

摘要： A braking control apparatus for use in a motor vehicle having at least one wheel comprising a master cylinder for generating a hydraulic pressure in response to a braking operation of a vehicle driver, an accumulator for accumulating a hydraulic pressure and at least one wheel braking cylinder for braking the wheel in accordance with a hydraulic pressure supplied thereinto. A passage system is provided so that the wheel braking cylinder is communicated therethrough with the master cylinder and the accumulator. In the passage system are provided first and second change-over valves for cutting off the pressure from the master cylinder, cutting off the pressure from the accumulator and a third control valve disposed between the wheel braking cylinder and the master cylinder or the accumulator for establishing and cutting off the communication therebetween. An control unit controls the operations of the first to third valves so as to, in response to cutting off the communication with the accumulator, establish the communication with the wheel braking cylinder, and then establish the communication with the master cylinder. This valve control prevents the high-pressure remaining in the passage system after the cutting-off of the communication with the accumulator from being rapidly applied to the master cylinder.
