Short crawler-mounted vehicle spray gun for applying adhesive material in motor vehicle construction, has outlet nozzle aligning with channel in opening position and lying eccentrically to channel in rotated valve needle in closing position

摘要

The gun has an integrated closing valve (12) including a valve needle (18) for closing the valve. The needle includes a channel (32) incorporated in a cylindrical body, where the channel arrives into a position averted from supply lines (24-30) laterally arriving into a valve housing in the closing position. An outlet nozzle (38) is arranged in a nozzle head (34) at end of the valve housing, and is formed in a carbide metal-insert (36). The nozzle aligns with the channel in an opening position, and lies eccentrically to the channel in the rotated needle in the closing position and is locked.
