Abstract: A quick-coupling valve, particularly for pressurized fluids, of the type which comprises, at a first end, a threaded coupling for reversible fixing to a supply hose and, at the second opposite end, the access to quick-coupling elements for a corresponding tubular male element, the valve having internally a first intake chamber for the pressurized fluid and a contiguous second discharge chamber, the two chambers being separated by reversible flow control elements intended to block the fluid, preventing it from passing through the valve when the male element is not inserted, the valve comprising elements which are intended to prevent the uncoupling of the male element when the valve is open and also comprising venting elements for safe uncoupling of the male element when the valve is closed. The valve comprises elements, associated with the flow control elements, for throttling the flow that passes from the first chamber to the second chamber.

Abstract: A hot air generating tool, comprising a tubular body for aspirating and discharging drying air, with which elements for heating the air and a handle are associated. The air heating elements are constituted by a Ranque-Hilsch vortex tube device supplied with compressed air.
