A high pressure air charger is provided to minimize the air loss and the manipulation by suppressing the air loss as a space between a needle and a charging valve. A high pressure air charger comprises a valve pin(6), and an O-ring(11a) and an urethane washer(5). A lever(3) operates to remove the air charging and the residual pressure removing. The air is filled to the direction of a needle(2) from a hose fitting(8) through an interval between the urethane washer and the valve pin. The valve pin rises with a compressed spring(7) and air pressure when the lever is released. The residual pressure remaining in the needle is ejected to the interval between a hollow bolt(4) and the valve pin. |
