Abstract: A pressure-actuated air gun having an actuating port in the nozzle of the gun such that, when the actuating port becomes blocked, as by inserting the nozzle of the gun into a coupling on an article to be inflated or deflated, air is caused to pass from a source of pressurized air to the gun. When the actuating port becomes unblocked, as by disengaging the nozzle of the gun from the coupling, air is inhibited from passing from the source of pressurized air to the gun. An air pilot actuated valve is interposed between the source and the gun, and is controlled by air pressure that builds up when the actuating port becomes blocked by the coupling.
