摘要： An antilock braking system and associated method for a four wheel automotive vehicle having front left and right wheels and rear left and right wheels with a determined weight distribution of the vehicle on the front and rear wheels, each wheel having a respective brake cylinder adapted for applying braking pressure to the wheel in response to pressure fluid supplied from a master cylinder. The supply of pressure fluid from the master cylinder to the brake cylinders during a braking operation is controlled in accordance with the weight distribution of the vehicle on the wheels to enable the front and rear wheels normally to undergo incipient wheel slip at substantially the same time. A fluid pressure regulating unit relieves the fluid pressure transmitted to the respective brake cylinders of the four wheels of the vehicle all at the same time when one of the two front wheels rotates at a higher circumferential speed than the other front wheel and indicates incipient wheel slip.

摘要： A hydraulic braking pressure control apparatus provided with a modulator for controlling the supply of control hydraulic pressure to a wheel brake of the vehicle, wherein a partition is provided between a first cylinder portion and a second cylinder portion which are formed in a casing, a first piston adapted to divide the first cylinder portion into an input hydraulic chamber on the partition side and a control chamber on the opposite side is secured to one end of a piston rod extending through the partition slidably and oil-tightly, and a second piston adapted to define an output hydraulic chamber on the partition side within the second cylinder portion is mounted on the other end of the piston rod for axial relative movement. The partition is provided with a valve mechanism capable of disconnecting communication between the input and output hydraulic chambers. The second piston is biased in a direction toward the partition, and by relative movement of the second piston with respect to the piston rod, the interior of the output hydraulic chamber is prevented from reaching an excessive negative pressure level during an anti-lock operation. The apparatus can function as a proportioning reducing valve by forming the first piston with a smaller diameter than the second piston.

摘要： A fluid pressure control system which includes an operational reaction force generating device having a piston which includes a front surface facing a pressure chamber and is operatively connected to an operating member so as to reduce a volume of the pressure chamber in response to the operation of the operating member. The fluid pressure control system further includes a fluid pressure control valve capable of adjusting and outputting an output pressure from a fluid pressure supply source capable of outputting a constant fluid pressure in accordance with the operation amount of the operating member and a stroke accumulator connected to the pressure chamber. The stroke accumulator is of a structural arrangement such that the resilient biasing force acting on the accumulator piston by the movement of the back-up piston toward the accumulator piston with the abnormal reduction in fluid pressure in the pilot chamber connected to the fluid pressure supply source is increased more than the fluid pressure acting on the accumulator piston when the fluid pressure in the pilot chamber is normal. Thus, it is possible in the fluid pressure control system of this invention to prevent the amount in which the operating member operates from being increased more than necessary when the output fluid pressure from the fluid pressure supply source is abnormally reduced.
