The present invention relates to a short caterpillar pistol for coating an adhesive or a sealant inside an automobile structure. The pistol has an integrated closing valve, and the closing valve includes a valve needle (18) for closing a valve. In the same situation, the valve needle (18) can be adjusted between an opening position and a closing position by a rotation performed around the selfsame vertical shaft. The valve needle (18) has a cylindrical body and a channel inserted to the body on the outer surface, and the channel reaches a position orienting the opposite side from supply lines (24, 26, 28, 30) inserted to the inside of a valve housing, when in the closing position. Inside a nozzle head (34) on an end portion of the valve housing, a discharging nozzle (38) is arranged, and the discharging nozzle is positioned on a straight line with the channel (32), when in the opening position. In a situation wherein the valve needle is rotated and positioned on the closing position, the discharging nozzle is eccentrically arranged about the channel, to become closed. |
