ABSTRACT:
A pressurized air jet actuated swing valve for sandblasters is hinged with respect to the underside of the inverted head of the sandblaster to fit squarely against the sand filling opening in the tank head whenever the swing valve is maintained in closed position due to air pressure within the tank. A pivotal shaft secured against the underside of a valve plate is loosely journalled at each end in a pair of opposed, vertical slots in brackets attached to the underside of the tank head for free downward swinging of the valve body with respect to the inside of the tank when the valve in its open position, while at the same time providing for self-adjustment seating against the tank head sand filling opening when closed.
