The spray gun includes a nozzle needle (31) connected with keyed engagement to the retraction arm (26) in the region of the guide sleeve (21) by an articulated bolt (27') engaging through the sleeve. The nozzle needle is held displaceable in a seal (32) which is inserted in the U-section guide sleeve between the supply line (16) and the articulated bolt. The seal holding the needle has on one or both sides one or more tabs projecting in the longitudinal direction of the needle and each with an elongated slit in which the projections on the needle engage. |
