Abstract: A pressure generating apparatus includes a master cylinder and a stroke simulator which has a pressure chamber communicated with a first master chamber, an atmospheric chamber communicated with a reservoir, and a piston member urged by a resilient member, and which absorbs brake fluid in response to the hydraulic pressure discharged from the first master chamber, to provide a stroke for a first master piston. The atmospheric chamber of the simulator is communicated with the reservoir when a second master piston member is placed in an initial position thereof, and blocks the communication between them, when the second master piston is advanced by a predetermined distance or more from the initial position.

Abstract: A vehicle brake apparatus includes a brake pedal, a wheel brake cylinder operatively mounted on a wheel for applying a braking force to the wheel in proportion to a hydraulic braking pressure, a pressure source for pressurizing brake fluid to generate a hydraulic braking pressure and supply the hydraulic braking pressure to the wheel brake cylinder, and an auxiliary pressure source for pressurizing brake fluid in response to operation of the brake pedal to generate a hydraulic braking pressure and supply the hydraulic braking pressure to the wheel brake cylinder when the pressure source is non-operational. A mechanical valve is operatively mounted between the wheel brake cylinder and the auxiliary pressure source. A first passage is connected between the auxiliary pressure source and the mechanical valve and a second passage is connected between the mechanical valve and the wheel brake cylinder. The mechanical valve permits brake fluid communication between the first and the second passages when the pressure in the first passage is less than a predetermined pressure, and permits brake fluid to flow from the first passage to the second passage when the pressure of the first passage is more than the predetermined pressure.

Abstract: To apply hydraulic pressure to a wheel brake upon failure of a stroke simulator, a brake pressure control device for automotive vehicles is designed so that when a power pressure source is in the normal condition, fluid communication between the master cylinder and the wheel brake is interrupted and fluid communication between the master cylinder and the stroke simulator is established, thus causing the output hydraulic pressure of the power pressure source to be adjusted in response to a detection output of a master cylinder hydraulic pressure sensor, thereby applying the resulting hydraulic pressure to the wheel brake. In addition, the brake pressure control device is provided with a stroke sensor which detects a stroke of a brake pedal. When the stroke of the brake pedal exceeds a predetermined stroke, a simulator cut-off valve is closed to interrupt fluid communication between the master cylinder and the stroke simulator.

Abstract: A load transmitting elastic member is interposed between an input rod and a piston of a master cylinder or a piston of a pedal stroke simulator to which the operation force of a brake pedal is applied from the input rod. The set load of the load transmitting elastic member is lower than the predetermined load required for causing the piston to begin to slide and the maximum load of the load transmitting elastic member is higher than the predetermined load required for causing the piston to begin to slide. The stroke of the brake pedal thus begins through application of a small depression force applied to the brake pedal and so the operational feeling of the brake pedal is improved.

Abstract: In a liquid pump for a braking system of a vehicle, one end of a piston is slidably inserted into a cylindrical space of a housing member, and a sliding ring is provided on the piston. A suction chamber is formed by an inner peripheral surface of the housing member, an outer peripheral surface of the piston and the sliding ring. An inner diameter “Dk” of the housing member is made larger than an inner diameter “Dc” of the cylindrical space. As a result, the volume of the suction chamber is increased, without making the piston smaller in its diameter.

Abstract: An improved brake hydraulic pressure generating device is provided in which the hydraulic pressure supplied from a hydraulic pressure source is adjusted to a value corresponding to the brake operating force by means of a pressure adjusting valve which is activated according to displacement of an input piston or a simulator piston, and while the device is normal, a master cylinder is activated by the output hydraulic pressure. If the hydraulic pressure source or a hydraulic line connecting thereto fails, a sufficient braking force is ensured with a short stroke. There are provided a shutoff valve which shuts off communication between the simulator chamber and the atmospheric reservoir when the stroke of the input piston has exceeded a predetermined value, and a check valve which permits the flow of fluid from the atmospheric reservoir to the simulator chamber. This suppresses an unavailable stroke of the simulator piston without impairing the return of the simulator piston.

Abstract: The invention is directed to a hydraulic braking system having a master cylinder (10) in which a first piston and a second piston are slidably disposed to define a first pressure chamber (11) and a second pressure chamber (12). A valve device (24) is provided between the first pressure chamber and a reservoir (20). A first pressure control device (30, 31) is provided between the first pressure chamber and wheel cylinders (38, 39), and a second pressure control device (32, 33) is provided between the second pressure chamber and wheel cylinders (40, 41). A pump (27) is provided in a passage connecting the reservoir and the first pressure control device, and driven to supply a brake pressure from the former to the latter. When the valve device is actuated to block the communication between the first pressure chamber and the reservoir, and the pump is driven, the pressure in the first pressure chamber will be increased to move the second piston, so that the pressure in the second pressure chamber will be increased. Accordingly, the pressure in each wheel cylinder may be controlled by the first or second pressure control device without depressing the brake pedal.

Abstract: A hydraulic brake device includes a hydraulic pressure supply passage for reducing the output hydraulic pressure by a first proportional solenoid valve and supplying it to a hydraulic passage leading from a pressure adjusting valve to the wheel cylinders, a second proportional solenoid valve disposed between the hydraulic pressure supply passage and the pressure adjusting valve for reducing the hydraulic pressure supplied from the hydraulic pressure supply passage, and a check valve parallel to the second proportional solenoid valve. Hydraulic pressure control during automatic brake control is carried out by the first and second proportional solenoid valves. When the brake pedal is operated during automatic brake control and output hydraulic pressure of the pressure adjusting valve exceeds hydraulic pressure in the hydraulic pressure supply passage by automatic brake control, the output hydraulic pressure of the pressure adjusting valve flows toward the hydraulic pressure supply passage through the check valve.
