Abstract:
A dual-purpose valve for a braking system includes a two-position hydraulic brake control valve coupled to a moveable valve member, a brake control chamber for holding fluid, a brake port for connecting to a brake cylinder, and a tank port for connecting to a fluid tank. Movement of the moveable valve member in a first direction towards a brake deactivation position from a neutral position maintains the hydraulic brake control valve in a closed state causes pressurised fluid flow from the brake control chamber to the brake port and thereby disengaging the braking system. Movement of the moveable valve member in a second direction towards a brake activation position from the neutral position alters the hydraulic brake control valve from a closed state to an open state, and permits pressurised fluid flow from the brake port to the tank port through the dual-purpose valve and thereby engaging the braking system.

Claim (Index 28):
A spring assisted hydraulic release braking system comprising:\n a brake cylinder; a drain or tank; and the dual-purpose valve of any preceding claim, wherein the brake port is in fluid communication with the brake cylinder and the tank port is in fluid communication with the drain or tank.
