摘要： The quick release valve has a chamber (32), an inlet opening leading (30) into the chamber for leading in pressurised gas and a connection opening (16) for connecting to a space (100) to be pressurised. The valve further has at least one outlet opening (24), through which the gas can quickly exit from the pressurised space in connection with the connection opening, and a piston (34), which is moveable between a first position closing the outlet opening and a second position opening the outlet opening. The piston is an substantially rigid plate-like part placed in the chamber, which part moves freely under the influence of air pressure. The chamber has a first surface (14a), where the mouths of the connection opening and the outlet openings open up, and the piston has a closing surface (36), which in the first position of the piston is arranged to settle against the first surface of the chamber. The closing surface of the piston thus simultaneously closes the mouths of both the connection opening and the outlet openings. The valve further has a bypass route (22, 23, 37) for leading pressurised gas into the connection opening past the piston in the first position.
