<p>PCT No. PCT/EP96/04267 Sec. 371 Date Apr. 23, 1998 Sec. 102(e) Date Apr. 23, 1998 PCT Filed Sep. 30, 1996 PCT Pub. No. WO97/15478 PCT Pub. Date May 1, 1997A tire inflation gun has a valve having several positions. When fully closed, the gun does not fill or empty a tire, but allows the tire pressure to be measured. When the valve is partially opened, the tire pressure can still be measured, but air is allowed to escape from the tire. Fully open, the gun allows the tire to be filled by a pressurized air source but closes the connection between pressure gauge and pressurized air source. This prevents the pressure gauge from being damaged by the high pressure.</p> |
