  • Floatation and anchoring mechanism for disc brake
    Patent number: 4068744
    Abstract: A disc brake is provided with a torque member having a pair of arms which define a recess which slidably receives one of the friction elements. The torque member and one friction element are designed so that braking torque is transmitted from the one friction element to the torque member through a primary abutment located on the lower edge of the recess, and a pair of secondary abutments. The other friction element is carried by a caliper which is slidably mounted on removable rails mounted on the upper end of the arms. The braking torque generated by the other friction element is transmitted through the caliper and the rails mounted on the other arm. Consequently, the braking torque is divided so that it is taken by several different portions of the torque member, thereby permitting a smaller and more efficient torque member.

  • Vacuum reducer valve
    Patent number: 4064894
    Abstract: A vacuum reducer valve is used in the distributor vacuum advance circuit in conjunction with an engine overheat detection three way valve which normally applies spark port vacuum to the distributor vacuum advance actuator. When the engine overheats, the spark port signal is blocked and manifold vacuum is applied to the distributor vacuum actuator. The manifold vacuum, however, averages three to four inches of mercury vacuum higher than the spark port vacuum thereby necessitating the use of a vacuum reducer valve in series with the manifold vacuum line to the distributor to avoid excessive spark advance.

  • Actuating and adjusting mechanism for disc brakes
    Patent number: 4064973
    Abstract: A mechanically actuated disc brake includes a wedge actuator which urges an extensible, force transmitting member toward the disc brake rotor in order to effect a brake application. A ratchet mechanism is carried by the extensible member and by a piston slidably mounted within the brake housing. The ratchet mechanism is responsive to movement of the extensible member toward the rotor in access of a predetermined amount in order to effect elongation of the extensible member to limit retraction in the piston, so that retraction of the friction elements is similarly limited. The extensible member also cooperates with a manual adjustment mechanism which may be used to manually adjust the brakes or to "back-off" the extensible member to permit movement of the friction elements away from the disc in excess of the predetermined amount when the friction elements must be removed when the brake is serviced.

  • Power assistance control device
    Patent number: 4057079
    Abstract: A fluid power assistance control device includes a rotatable input, a first valve coupled to the input and a second valve. The second valve is rotatable relative to the first valve and a projection between the first and second valves limits the rotation therebetween. The projection cooperates with the valve to substantially define fluid paths which communicate with an outlet and also defines flow restrictions within the paths such that rotation between the valves increases flow restriction in one of the fluid paths and decreases flow restriction in another of the fluid paths. The valves cooperate to define reaction cavities which communicate with respective fluid paths so that fluid communicated to one of the reaction cavities opposes the rotation of the input.
