ABSTRACT:
A container for receiving a charge of pressurized air and storing the air in this container until released through a blast nozzle and having a quick dump valve apparatus within this container. In one embodiment a valve includes a removable pipe which contains a large slidable piston which opens and closes the flow of accumulated air to the discharge. This piston is moved in response to a solenoid actuated small piston which is moved in a small tube. This small tube extends through the large piston and it slides therealong. In another embodiment a ball valve is employed in a tubular chamber. An external three-way quick acting valve actuates the flow of pressurized air to the valve and to a venting to atmosphere. The ball is slightly smaller than the internal diameter of the tubular member so that pressurized air may flow by the ball in a forward position and into the container.
