Title:
HIGH PRESSURE AIR PLUGGER
Document Type and Number:
WIPO Patent Application WO/2011/013932
Kind Code:
A2
Abstract:
The present invention relates to a device for charging high pressure air into an air tank of an air gun or the like, wherein the device is formed in a structure in which charging and remaining pressure eliminating operations are implemented merely by pressing and releasing a lever (3). If the lever (3) is pressed, a valve pin (6) moves downwards so that air is charged by passing a gap between the valve pin (6) and a urethane washer (5) in the direction from a hose fitting (8) to a needle (2). If the lever (3) is released, the valve pin (6) moves upwards by a compression spring (7) and air pressure, so that the air flow is blocked in the gap between the valve pin (6) and the urethane washer (5), and the remaining pressure in the needle (2) is discharged through a gap between the valve pin (6) and a hollow bolt (4) by passing through a gap between the valve pin (6) and an O-ring (11). Therefore, the time required for charging and remaining pressure eliminating operations can be shortened compared to the existing method, and air loss amounting to the space between a charging valve and a remaining pressure eliminating valve can be reduced.
