<p>PURPOSE: A valve provides a simple valve construction without the use of threads or mechanical parts. CONSTITUTION: A flange (2) with a circular cylindrical opening (4) is provided in an inflation valve (1) for a container with non-rigid walls which is to be air pressurized, said flange (2) being secured to the container. A filling nozzle (6) communicating with a valve body (9) is mounted with an O-ring (7) in the opening (4) of the tubular part (3). According to the invention the valve body (9) with the filling nozzle (6) is pivotally arranged in the tubular part (3) and provided with a conical inner wall (13) to which a conical valve member (16) is secured. The valve member closes a gas supply passage (14) provided with a snugly fitting opening (15) for receiving a gas supply tube (18), one end (19) thereof adapted to mechanically pushing the valve member (16) aside at insertion of the gas supply tube (18) such that the inflation valve (1) is opened.</p> |
