摘要： A fluid pressure source apparatus includes a pump, an accumulator for receiving pressure from the pump, a pressure switch for detecting the pressure in the accumulator, an electric motor for driving the pump, and a motor control device for driving the motor when the pressure switch detects a low pressure. A current detecting device detects a motor current value of the motor and a control unit determines whether the accumulator or the motor is experiencing an abnormality based on the motor current value. The control unit determines whether the motor current value occurring during a first set time following the start of driving of the motor is greater than a first set value. If the motor current value is not greater than the first set value, the control unit determines that the current detecting device is experiencing an abnormality. If there is no such abnormality information, the control unit compares the motor current value with predetermined values. If the motor current value continues to be less than a lower limit value for at least a predetermined length of time, the control unit determines that there is a low pressure abnormality. If the motor current value continues to be greater than an upper limit value for at least a predetermined length of time, the control unit determines that there is a motor lock abnormality.

摘要： A wheel brake pressure supplying device for supplying fluid pressure for a wheel brake cylinder of a wheel on an automotive vehicle includes a reservoir, a pump, a motor, an accumulator connected to the wheel brake cylinder, a fluid pressure sensor, an electric source, an operation time determining device and a motor control device. The reservoir stores a fluid and the pump is connected to the reservoir for pumping fluid in the reservoir. The motor operates the pump and the accumulator is connected to the pump for storing the fluid pumped by the pump so that fluid pressure in the accumulator increases through operation of the pump. The fluid pressure sensor senses when the fluid pressure in the accumulator is less than a predetermined pressure. The electric source is connected to the motor for supplying voltage to the motor and the operation time determining device determines a target operation time of the motor based on the voltage of the electric source. The motor control device starts the operation of the motor when the fluid pressure in the accumulator is less than the predetermined pressure and terminates the operation of the motor when the operation time of the motor reaches the target operation time.

摘要： A pressure control accumulator for hydraulic brake systems includes a housing having a brake fluid port and a cavity communicating with the port. A staged series of resilient membranes is disposed within the cavity for nullifying hydraulic brake fluid pulsations over a wide range of pressures. The staged series preferably includes a resilient diaphragm disposed adjacent the port for nullifying hydraulic brake fluid pulsations at low and normal pressures by itself and maintaining the brake fluid on one side of the diaphragm, and a resilient membrane disposed remote from the port and normally spaced from the diaphragm, the diaphragm and the remotely-disposed membrane cooperatively nullifying hydraulic brake fluid pulsations at high pressures by providing a plurality of resilient resistances in series. The remotely disposed membrane may be a second diaphragm.

摘要： A pressure source for a pressure device has a pump for pumping fluid from a tank, an accumulator connected to the pump and to a pressure device, a device for detecting the pressure in the accumulator, and a control system for controlling the operation of the pump in an ON/OFF manner based on results of detection of the pressure detecting device. The pressure detecting device includes a pressure switch to detect pressure in the accumulator to produce an ON/OFF signal, and a pressure sensor outputting a pressure signal corresponding to pressure in the accumulator. The control system judges whether the pressure sensor is normal or out of order, and when the pressure is normal, controls the operation of the pump with the pressure signal. The pressure signal and the ON/OFF signal are compared with each other, and when these signals do not correspond, the pressure switch is determined to be out of order, and when the pressure sensor is out of order, the pump operation is controlled with the ON/OFF signal. In this way, the pump can be controlled appropriately, irrespective of any trouble or abnormality in the detecting device.

摘要： A hydraulic brake system having an anti-skid system in which its rear axle brake circuit has a pressure control device switchable by a control pressure; if the anti-skid system should fail, this device reduces the brake pressure in the rear wheel brake cylinders. The hydraulic brake system includes the pressure control device which acts as a proportional pressure regulating valve and is switchable by a pressure prevailing on a master brake cylinder side of a return pump; if the anti-skid system should fail, this device reduces the pressure of the pressure fluid in the wheel brake cylinders by a fixed proportion compared with the pressure toward the master brake cylinder. The pressure control device has a very simple, compact design and is especially suitable for use in the rear axle brake circuit of a motor vehicle.

摘要： A throttle-controlled hydraulic power brake employing a pressurized fluid produced via a pump and preferably stored in an accumulator for enabling servo-assisted displacement of a push rod acting on the master cylinder of a brake pump (of the same type employed on vacuum-operated power brakes) subsequent to axial displacement of a second push rod controlled directly by the brake pedal. Displacement of the second push rod towards the first provides, against the action of elastic means, for opening a first face seal valve, which feeds the pressurized fluid into a variable-volume accumulating chamber, so as to displace a piston connected axially to the first push rod and defining a movable wall of the accumulating chamber, and so close the valve. Opposite displacement of the second push rod, on the other hand, provides for opening a second face seal valve connecting the accumulating chamber to a drain.

摘要： A pressurized fluid brake system for automotive vehicles of the type where the brake pedal pressure (F) is transmitted with assistance of an auxiliary pressure force to the wheel brake cylinders through pressure lines containing pressure modulator valves. The wheels are provided with transducers for measuring instantaneous wheel rotation as well as vehicle velocity. Electronic control circuitry processes and logically combines the measured values to generate control signals for the pressure modulator valves. Preferably, the modulator valves are electromagnetically actuatable valves. By virtue of the braking pressure modulator valves, brake force distribution is controlled in dependence upon the brake slip of the front wheels and, in addition, a brake slip preventing locking of the vehicle wheels will be performed.
