ABSTRACT:
A sealed tank normally receiving air under pressure is connected with respect to a shuttle valve so that when there is an accidental loss of pressure, the air in the tank moves the valve to a position where the high pressure in the tank is applied to an intensifier piston placing a brake or the like in operation. By using a three-way valve in the main supply line the brake may be cycled at will merely by an appropriate turn of the valve.
