    Abstract: A centrifugally controlled differential brake uses a plurality of disc brake pads which are urged against a non-rotating braking surface. The disc brake pads are each slidably mounted on a respective one of a plurality of first support rods and spring loaded to a position at one end of the corresponding rods. The other ends of the plurality of support rods are attached to a hub on which the rods are radially arranged and equally spaced. The hub is connected to a shaft to which a braking torque is to be applied. Each of the brake discs is connected by a connecting link to a respective one of a plurality of centrifugal weights which are each slidably mounted on a respective one of a plurality of second support rods. The second support rods are radially attached to the hub and equally spaced with each of the second rods being aligned diametrically opposite a respective one of the first rods. Thus, the springs urge the brake discs to an outer diameter position while the centrifugal weights are correspondingly positioned at an inner diameter position. During a rotation of the shaft, hub and first and second rods, a movement of the centrifugal weights on their respective second support rods counteracts the effect of the springs to urge the brake discs toward an inner diameter position in proportion to the rotational speed to vary the braking effect by a variation in the length of the torque arm of the brake disc.

    Abstract: In a fluid pressure control valve unit, a pair of first and second partition members are assembled within a housing to subdivide the interior of the housing into first and second chambers and to provide a space between the partition members. The first chamber is in open communication with an outlet port for connection to rear wheel brake cylinders, and the second chamber is in open communication with an inlet port for connection to a master cylinder. Assembled within the first chamber are a stepped piston and a control valve assembly cooperable with the piston. The piston extends through the first partition member into the space, and a control plunger is slidably disposed within an axial bore of the second partition member to provide a third chamber opening toward the second chamber. An inertia-control valve assembly is disposed within the second chamber to control the pressure in the third chamber in accordance with the rate of deceleration. In such arrangement, one of the partition members is provided at its peripheral portion with a fluid communication passage between the first and second chambers.

    Abstract: A control valve assembly for a vehicle braking system comprises an inlet, an outlet, a proportioning valve having a control valve member movable to open and close the valve to control communication between the inlet and the outlet, and an inertia-responsive device, preferably a pendulum, responsive to deceleration of the vehicle and operable to reduce the pressure at the outlet after the valve has closed. The inertia-responsive device supplies a signal in dependence upon deceleration, and a servo system applies a force to the control valve member in response to the signal to move the control valve member in a direction to reduce the outlet pressure. The servo system comprises an auxiliary valve operable in response to movement of the inertia-responsive device, a pressure operable member subjected to a pressure in dependence upon operation of said auxiliary valve, and an arrangement coupling the pressure operable member in force-transmitting relation with the control valve member, whereby said control valve member is subjected to a force which is dependent upon the vehicle deceleration.

    Abstract: A combination valve assembly for a dual circuit brake system in which a metering valve is in one circuit, a proportioner is in the other circuit, and a hydraulically reset pressure loss warning indicator unit is sensitive to both circuits. The proportioning action rates change to match vehicle loading, to accommodate uphill and downhill grades, and to accommodate any brake fade. This is accomplished providing a deceleration sensing mechanism, including the inertia valve of the invention, which locates the proportioner piston to determine the amount of proportioning required based on the pressure at which deceleration triggers an inertia valve in the proportioner. Actuation of the warning unit because of pressure loss in the metering valve circuit causes the proportioner to be overridden by removing a valve element from a closed position to permit direct flow so that pressure through the proportioner is not proportioned.
