Title:
VALVE GEAR
Document Type and Number:
WIPO Patent Application WO/2005/007524
Kind Code:
A1
Abstract:
A valve gear usable without being aware of the diameter of the nozzle of a suction device, not giving damage to the other portion, for example, an enclosed bag stacked on or adjacent to the outer surface thereof, and allowing the stacked or adjacent load profile to be brought in a flat stable state. A suction connection part (2) installed on the outer surface of the enclosed bag in which a hole is formed and having a vent port (2a) formed at the center part thereof is formed in a flat shape, and a valve base material (3) fitted to the inner surface side of the enclosed bag is formed in a recessed shape in cross section. Since the nozzle is merely brought into contact with the suction connection part (2) so as to cover the vent port (2a), the valve gear can be used without being aware of the diameter of the nozzle. Also, since a projected portion from the outer surface of the enclosed bag is eliminated, the other portion, for example, the enclosed bag stacked on or adjacent to the outer surface thereof is not damaged, and the stacked or adjacent load profile can be brought into the flat stable state.
