Abstract: In a brake fluid control device, front wheel cylinders are connected to a front hydraulic circuit, and rear wheel cylinders are connected to a rear hydraulic circuit. The front hydraulic circuit and the rear hydraulic circuit are connected to a front left pressure-decrease valve, a front right pressure-decrease valve, a rear left pressure-decrease valve, a rear right pressure-decrease valve and a connecting pipe. When a brake pedal is depressed, the front left pressure-decrease valve, the front right pressure-decrease valve, the rear left pressure-decrease valve and the rear right pressure-decrease valve are opened and a master cylinder pressure sensor leads to both the front hydraulic circuit and the rear hydraulic circuit. Comparing a detection value of the of the master cylinder pressure sensor, a detection value of a front wheel cylinder pressure sensor and a detection value of a rear wheel cylinder pressure sensor respectively, detects the state of operation of each of the sensors provided in the system.

Abstract: A brake fluid pressure control apparatus achieves a sufficiently large brake force even when a malfunction occurs in an operational force sensor for detecting a level of operational force applied to a brake system. A magnitude of a master cylinder pressure generated by a master cylinder is detected by a master cylinder pressure sensor. A linear fluid pressure source generates a linear fluid pressure adjusted by the magnitude of the master cylinder pressure. Front wheel cylinders and rear wheel cylinders are provided with the linear fluid pressure. A front wheel cylinder pressure is detected and a front wheel cylinder pressure value corresponding to a magnitude of the front wheel cylinder pressure is output by a front wheel cylinder sensor. If it is determined that a malfunction is occurring in the operational force sensor, a connection of the front wheel cylinders is switched from the linear fluid pressure source to the master cylinder.

Abstract: When oil is discharged from an actuator 11i for lowering a vehicle height, an actuator pressure Pa is higher than a pump pressure Pp so that a differential pressure valve 41 slides its valving element 42 to the left by a pressure difference. A valving element seal portion 42b, abutted against a seat face 43a closing an opening of a lower return conduit 40b, moves from seat face 43a and open to lower return conduit 40b. As a result, the closure of the connected portion in the lower return conduit 40b is opened. Thus, the passage of a return conduit 40 is opened. Then, the oil from the actuator 11i is discharged via the return conduit 40 to the reserve tank 16 while receiving less flow resistance by avoiding a passage through any solenoid valve.

Abstract: An anti-lock brake system for a wheel wherein a fluid pressure is applied to a wheel cylinder, through a solenoid-operated valve device and a flow control device. Upon detection of locking of the wheel, the valve device is brought into an anti-lock state in which the valve device is alternately placed in its pressure-increase and pressure-decrease positions. The flow control device is normally placed in a first mode for a sufficient flow of the fluid into the wheel cylinder, and is operated in a second mode with the valve device placed in the anti-lock state. In the second mode, the flow control device decreases the rate of fluid flow to the wheel cylinder, with an increase in a difference between the power source pressure and the wheel cylinder pressure. An assisting device is provided for enabling the flow control device to adequaely effect the first mode of operation for at least a period between commencement of brake application and commencement of anti-lock operation of the valve device.
