Abstract
A wet brake cooling fluid system includes a cooling fluid supply line that is divided into a plurality of parallel paths. One path is in fluid communication with the motive side of a venturi eductor pump. Another pump is directed into the brake after passing through a fixed orifice that restricts flow. At least on path is in fluid communication with the brake after passing through a valve that is piloted to a brake piston, the valve only opening upon actuation of the brake. A drain hose connects the brake to the suction side of the venturi eductor pump, thereby causing evacuation of the fluid from the brake. Due to the restriction of fluid flowing into the brake by the valve, the brake chamber remains substantially empty during non-braking conditions, and is flooded upon actuation of the brake and opening of the valve.
