    Abstract: A brake activating apparatus, allowing a dual lever ratio for applying a force from the brake pedal to a valve operating rod of a power booster which communicates with the master cylinder. A brake activating lever arm is pivotally secured to a vehicle. A pivot pin carrying a first force transmitting member is located at a fixed distance from the end of the lever arm. A yoke member, attached to the lever arm at a different fixed distance from the end, is connected to a vacuum chamber housing. A diaphragm contained within the vacuum chamber is secured to a second force transmitting member. The valve operating rod for a power booster communicating with the master cylinder has a bored chamber to receive the first transmitting member and a U-shaped member surrounding the chamber to secure the second transmitting member. When the brake lever is moved, the applied force is transmitted through the yoke and second transmitting member as long as the pressure differential retains the diaphragm member in a fixed position. If the diaphragm member is free to move, the first transmitting member contacts the end of the bored chamber and transfers the applied force from the lever arm, at a different ratio, to the valve operating rod communicating with the master cylinder. In another embodiment, the second force transmitting member carries the applied force until the force required to move the valve operating rod is greater than a resilient member whereupon the resilient member collapses permitting the applied force to be transmitted through the first force transmitting member.

    Abstract translation: 一种制动器启动装置，允许将双重杆的比例从制动踏板施加到与主缸连通的动力助力器的阀操作杆。 制动激活杆臂枢转地固定在车辆上。 承载第一力传递构件的枢轴销定位在与杠杆臂的端部固定的距离处。 以与端部不同的固定距离附接到杠杆臂的轭构件连接到真空室壳体。 包含在真空室内的隔膜固定到第二力传递构件。 用于与主缸连通的动力助力器的阀操作杆具有用于接收第一传动构件的钻孔室和围绕室的U形构件以固定第二传动构件。 当制动杆移动时，只要压差将隔膜构件保持在固定位置，施加的力就通过轭和第二传递构件传递。 如果隔膜构件自由移动，则第一传递构件接触钻孔室的端部，并以不同的比例将杠杆臂施加的力传递到与主缸连通的阀操作杆。 在另一个实施例中，第二力传递构件承载施加的力，直到移动阀操作杆所需的力大于弹性构件，于是弹性构件塌缩，允许施加的力通过第一力传递构件传递。

    Abstract: A control for a power brake system having a servomotor as the source of power. The servomotor has a housing with a diaphragm dividing it into front and rear chambers. Vacuum from the intake manifold of a vehicle is supplied to the front and rear chambers to suspend a power piston attached to the diaphragm member. A valve member secured to the rear chamber and responsive to movement of the brake pedal closes the vacuum communication in the rear chamber creating a pressure differential across the diaphragm member. This pressure differential causes the diaphragm member to move the power piston of the servomotor. A relay valve is placed in the vacuum line supplying the front and rear chambers. When the vacuum in the servomotor is below a predetermined value, the communication to the front chamber is sealed thereby assuring a pressure differential across the diaphragm upon brake application. A check valve is placed between the intake manifold and the relay valve which allows flow of air from the chambers but prevents backflow when the intake manifold vacuum is low. A vacuum reservoir has been provided to help maintain the vacuum level in the system when the manifold vacuum is low. In this brake system a number of brake applications are assured with power assist when the motor of the vehicle is not running.

    Abstract: A relay control valve operatable by a control pressure to monitor a slave servomotor which valve has additive pressure responsive elements adapted to be effective at progressively different values of the control pressure whereby the ratio of the control pressure for the valve with respect to a control pressure from the valve to the slave servomotor is variable. In addition, the valve can be linked with an antiskid control system to maximize effectiveness of the slave servomotor on at least a portion of a vehicle''s brake system in which incorporated.
