摘要： A tandem master brake cylinder has first and second pistons, each piston associated with a fluid chamber and a pressure chamber. The pistons are displaced in response to actuation of a brake pedal. A hydraulic booster is coupled to a power source and is operable to enhance the piston movement and for conducting pressurized fluid to a second of the fluid chambers associated with a second piston to displace that piston in a manner reducing the volume of the pressure chamber associated with the first piston. In the event that a negative pressure is communicated with the second fluid chamber, e.g. by a loss of pressurized fluid from the power source, brake fluid is supplied through a one-way check valve to the second fluid chamber to prevent the negative pressure from reversing the motion of the second piston.

摘要： A pair of spaced apart large-diameter and small-diameter lands between which a fluid chamber is defined are formed on a second piston in a tandem cylinder to which an anti-skid device is added. Booster pressure is applied to the fluid chamber to act on the large-diameter land in a manner fluidly locking the second piston against movement despite a reduction in pressure in the first and second pressure chambers during operation of the anti-skid device. As a result, the movement of the brake pedal in the normal direction of depression is prevented when the anti-skid devices operates.

摘要： A hydraulic braking system includes a tandem master cylinder having a bore with an opening and a closed wall at opposite ends thereof which formed in a housing, a first piston slidably fitted in the bore so as to define a first pressure chamber and a first fluid chamber therein and operatively connected to a brake pedal, a second piston slidably fitted in the bore so as to define a second fluid chamber adjacent to the first pressure chamber and a second pressure chamber and operatively connected to the first piston. A normally open valve communicates with each piston so as to close passages formed in the each pistons and communication between each fluid chambers and each pressure chambers, respectively, when each piston is moved in response to the depression of the brake pedal. A power source generates a hydraulic power pressure. A dynamic hydraulic braking pressure generator generates the hydraulic power pressure supplied from the power source in response to depression of the brake pedal and outputs to the second fluid chamber. A plurality of wheel cylinders for braking respective road wheels are divided into a first group of wheel brake cylinders communicated with the first pressure chamber through one of dual hydraulic circuits and a second group of wheel brake cylinders communicate with the second pressure chamber through an another of the dual hydraulic circuits. A restrictor restricts the sliding distance of the second piston toward the first piston to at least a predetermined distance for closing the valve means. Due to such construction, the first stage idle stroke of the tandem master cylinder is shortened and the stroke of the brake pedal is shortened.

摘要： A relief valve used for hydraulic devices such as the master cylinder for motor vehicles, comprising a housing for passing hydraulic fluid therethrough to adjust the hydraulic pressure, a ball valve disposed in the housing, a coil spring for pushing the ball valve in the housing and plural finger-like portions formed in the inside of the housing to resiliently nip the ball valve so as to prevent the vibration of ball valve in the direction of diameter of the housing at the time of releasing hydraulic fluid through the inside of the housing, thereby making it possible to avoid the generation of strange noise by the vibration of ball valve. It is desirable to form the surface of valve body or the valve body side surface of the finger-like portions so that it has a surface roughness within a specific range in order to make the noise prevention effect more perfect.

摘要： A disc brake free from dragging torque while being in non-braking state. In this brake, a gap between the friction surface of a rotary disc and the acting surface of an actuator for urging a braking pad assembly onto the disc is made progressively larger into a wedge shape toward the axis of the disc. The torque receiving surface of a torque receiving member is made so slant as to produce a component for moving the pad assembly in a direction away from the axis of the disc in a wedging manner into the gap. The pad assembly is of corresponding shape to the above-mentioned gap and the torque receiving surface. The pad assembly is moved in case of brake application in a direction away from the axis of the disc by virtue of the slantingly shaped torque receiving surface until it comes to abut on a stopper, and it is restored in case of brake releasing in a direction approaching the axis of the disc, due to the action of return springs, with a result of appearing of a preset brake clearance responding to the restoration of the pad assembly in the wedge shaped gap.

摘要： A tandem master cylinder with a booster used for a hydraulic actuator such as an automotive brake system. The master cylinder has a first and a second independently movable presser piston disposed in tandem in a first housing such that the presser pistons and the first housing define a first and a second pressure chamber. The booster has a first power piston advanced by a fluid pressure in a first power chamber formed in a second housing, to advance the first presser piston. The booster has a valve operable due to a relative movement between the first power piston, and an operating member for operating said booster, whereby the fluid pressure in the first power chamber is controlled according to an operating force applied to the operating member. In a third housing, there is disposed a second power piston, which has opposite pressure-receiving faces one of which receives a fluid pressure in the second pressure chamber, the other face receiving a fluid pressure in a second power chamber, whereby the fluid pressure in the second pressure chamber is controlled according to the fluid pressure in the second power chamber. The second power chamber is connected to the first power chamber.
