A painting air brush draws and sprays ink from an ink jet tube member (1) in the presence of a negative pressure produced when air is ejected from an annular air jet outlet encircling an ink jet outlet (2a, 2b, 2c) of said ink jet tube member. A valve mechanism (8a, 9) provided at a rear end of the ink jet tube member controls the amount of ink released to the ink jet tube member. No needle member at the forward end of the ink tube member is used for controlling the ink supply amount, which prolongs the life of the air brush and ensures high-speed, stable ink jet for a long time. <IMAGE> |
