Abstract

636,397. Spray-producers. AKTIEBOLAGET COLORATOR. Dec. 17, 1946, No. 37122. Convention date, Jan. 17. [Class 69 (iii)] A fan-shaped spray from a slot-like nozzle has pressure and suction air or gas jets acting thereon, tending respectively to compress and expand its cross-section in the direction of the slot major axis. In the embodiment a spray gun for paint and the like has diametrically opposed pairs of air or gas pressure jets 14 and 15. Jets 14 converge towards a point in front of the spray nozzle 34 having a slot-like opening, and jets 15 diverge outwardly, the former pro. ducing a pressure and the latter a suction on the liquid spray. A single rotatable valve body 16 with passages 18 and 19 regulate the supply of fluid through channels 10 and 11 to the jets 14 and 15 respectively. A further rotatable valve 22 in a channel 20 regulates the supply of pressure fluid to an annular space 25, the fluid passing through openings 26 and 27 to an atomizing chamber 9. A portion of this fluid passes in front of chamber 9 through channel 28 and opening 29. The spray liquid is fed to chamber 9 via channels 2 and 7, the latter channel being controlled by a valve 6. Specification 563,174 is referred to.
