摘要:
Brake holding apparatus for use in a vehicle having a fluid pressure operated braking system including a master cylinder and at least one brake cylinder. The apparatus includes a trapping valve movable to an open position allowing fluid communication between the master and brake cylinders, and to a closed position blocking this fluid communication so as to trap fluid pressure in the brake cylinder. The trapping valve is biased for movement to its open position. Means are provided for moving the trapping valve to its closed position. A bypass valve allows fluid communication from the master cylinder to the brake cylinder, but blocks fluid communication in the opposite direction. The trapping valve is fluid pressure balanced such that fluid pressure trapped in the brake cylinder has no effect on the position of the valve.
