  • Safety-brake control system for vehicles
    Patent number: 4166513
    Abstract: A safety-brake control system for a vehicle for the automatic actuation of the parking-brake valve to the brake-applied position comprising a lever arm connected at one end to the actuator of the valve and at the other end to a flexible connector element which in turn is connected to the moving arm of a solenoid. Energization of the solenoid pulls the flexible connector element to move the lever arm to actuate the valve to the brake-applied position. The valve thereafter can be actuated to the brake-released position by manual movement of the valve actuator.
