    Abstract: An angular deceleration sensor adapted for sensing by the overrunning of a flywheel an angular deceleration in excess of a predetermined value of a detected subject which rotates in a fixed direction. A clutch is interposed between the flywheel and a drive shaft for transmitting the rotation of the subject to the flywheel, the clutch being in the form of a unidirectional clutch which assumes a locked state when the drive shaft is in a drive position with respect to the flywheel.

    Abstract: A hydraulic braking pressure control valve for use in a vehicle includes a first inlet and outlet connected to a first pressure circuit, a second inlet connected to a second pressure circuit, a first piston having therethrough a liquid passage which normally connects the first inlet and outlet, a second piston receiving liquid pressure in the second inlet for displacing the first piston against the biassing force of a pressure control spring, and a valve mechanism associated with the first piston for closing the liquid passage when the first piston is displaced by a predetermined distance by the second piston. A plunger is provided with one surface thereof facing the first piston with the pressure control spring interposed therebetween and the other surface thereof receiving liquid pressure from the first pressure circuit, and an inertia valve is provided for cutting off the supply of liquid pressure to the other surface of the plunger at a predetermined deceleration of the vehicle.

    Abstract: The disclosed motor vehicle hydraulic brake system includes a master cylinder supplying fluid pressure to a front brake circuit and to a rear brake circuit. The rear brake circuit includes a proportioning valve which reduces the pressure supplied to the rear wheel brakes. The rear brake circuit also includes a control circuit. In the event of front and rear braking pressures exceeding predetermined pressure levels, the control circuit modifies the operation of the proportioning valve so that the proportional relationship of the proportioning valve closely approximates a 0.4g deceleration line until the theoretically ideal front to rear pressure relationship for the particular loading condition of the vehicle at the 0.4g deceleration rate is reached. The proportioning valve then closely approximates the theoretically ideal front to rear pressure relationship for the particular loading condition of the vehicle at all higher braking pressures and higher deceleration rates.

    Abstract: The device has a differential plunger axially movable in a stepped bore formed in a housing for modulating a first fluid pressure supplied thereto when the pressure exceeds a critical magnitude, wherein one end face of the plunger is exposed exclusively to a second fluid pressure of which modulation is unintended, and the other end face is isolated from the first and second fluid pressures but receives such a compression force from a spring installed thereon between a piston that the critical magnitude is raised if the second fluid pressure is not supplied to the former end of the plunger. The piston is exposed to the first or second fluid pressure through a normally open valve, and a movable member is disposed in the housing, which member moves and closes the valve when the device is subjected to a deceleration larger than a predetermined magnitude, so that the critical magnitude of the first fluid pressure is raised as the weight of the vehicle increases.

    Abstract: A proportioning valve for a vehicle braking system is disclosed which includes a pair of valve members slidably disposed within a housing and cooperating with the latter to define an inlet chamber connected to the vehicle''s master cylinder and an outlet chamber in fluid communication with the rear wheel brakes of the vehicle. The valve members initially permit uninhibited fluid communication between the inlet and outlet chambers until a predetermined relationship exists between vehicle deceleration and the pressure level in the valve, whereupon the valve members cooperate with one another to restrict fluid communication between the inlet and the outlet chambers to thereby establish a lower fluid pressure level in the outlet chamber than the fluid pressure level established in the inlet chamber.
