Abstract

The device comprises an air receiver (7) having its inlet connected to a manually operated pumping unit (3, 33) for its filling with compressed atmospheric air, between said pumping unit and said receiver (7) there being interposed a valve unit comprising a non-return valve (77) positioned to intercept the delivery conduit of said pumping unit; a valving element (10) slidingly housed air-tight inside a passage chamber (12) into which said delivery conduit opens, and arranged to close the outlet of the receiver (7); a vent valve (24), controlled by a trigger operable from the outside, to intercept a channel (25) which connects said passage chamber (12) to the outside; and a duct (11) which passes through said valving element (10) and has one end constantly connected to said passage chamber (12) and its other end opening into the outer cylindrical surface of the valving element (10); said valving element (10) is provided with elastic means (15) arranged to maintain the valving element (10) constantly urged towards its closure position, the thrust of said elastic means (15) being overcome by the thrust produced by the pressure downstream of the valving element (10) when the passage chamber (12) is connected to discharge.
