Definitions

  • This invention relates to a spraying apparatus for atomizing paint and other liquids, which is simple in construction and inexpensive to manufacture although ensuring efficient operation.
  • the principal part of said apparatus occupies so small a space that when taken apart from the liquid container and the source of pressure it may be held in the hollow of the hand.
  • the apparatus constructed in accordance with the present invention operates much better than guns of more complicated make, but it does not require a very powerful source of pressure, it may for example work perfectly well with the garage apparatus known as infiator.
  • the invention is substantially characterized in that the atomizer comprises a fiat liquid aperture, on either side of which are placed two air ejectcrs limited by two fiat walls in parallel with the axis, the air inlet channel to said ejectors opening upon one of said walls in the direction ofthe other wall and of the liquid aperture in such a manner that the liquid is drawn in and atomized by two air sheets which cut one another in front of said aperture and that the liquid sheet is limited along two flat surfaces in parallel with the portions of both air jets that are deflected by the second wall of each ejector.
  • the appended drawing shows by way of example a mode of execution of a spraying apparatus constructed according to the present invention.
  • Fig. 1 is a longitudinal section illustrating the whole apparatus.
  • Fig. 2 is a view drawn in the direction of thearrows 2-2 in Fig. 1.
  • Fig. 3 is an end view.
  • the apparatus as therein shown comprises a body I provided with a nozzle 2 for the admission of air pressure in chamber 3 and from which extend horizontal passages 4 opening in front in a second chamber 5 formed in an end piece 6, fixed upon the body I by means of a nut 1.
  • a middle hollow atomizing valve or a liquid suction nozzle H having two sides ll in parallel with the axis and with the aforesaid sides Ill.
  • the nozzle H which is screwed in the end piece 6 is provided with an outlet orifice l2 having prefer- PATENT OFFICE nozzle that is to say flat.
  • the orifice of the atomizing nozzle is so situated that the air jets coming out of the orifices 9 are divided into two equal portions one of which strikes the side I I and the other which is not deflected comes to join in front of said orifice, in the axis, the similarportion of the other air jet.
  • the passage H in the atomizlng nozzle is ex- 10 tended inside the end piece 6 by a passage [4 which by the intermediary of a packing inserted between said end piece and the body I, connects with another passage l6 opening in a vertical channel IT. Said channel reaches down to the liquid inlet nozzle l8 which may be connected to a paint pot or other container by means of a suitable piping or in any other way.
  • the channel l1 may communicate at its upper end with the atmosphere either directly at H! as shown in the drawing or by the intermediary of In the case illustrated in the drawing, when the connections between the air pressure source and only to close the aperture H! with one finger of the hand that holds the apparatus in order-to cause the liquid or the paint to be projected in the shape of a fiat sheet having parallel edges.
  • both orifices 9 In fact the air jet coming out of both orifices 9 is divided into two portions. One of them is not deflected and meets the similar portion of the other air jet along the axis in front of the liquid aperture drawing in and atomizing said liquid. The other portion of both air jets is deflected by the side II and limits the liquid sheet along a plane surface in parallel with the axis.
  • the elementaryeffects thusobtained are really more complicated but the result is that which has just been stated, that is to say the projection of a strictly fiat liquid sheet.
  • the discharge and the flattening may be regulated by screwing and unscrewing the atomizing valve II, when in its most favourable position.
  • it is desired to stop the projection it is only necessary to raise the finger so as to uncover the aperture I9. This resulting in a short' circuiting of the suction along
  • a spraying apparatus for atomizing paint and other liquids comprising a frame having an air inlet formed therein, a liquid suction nozzle conn-ected with said frame, a tubular middle spout integral with said nozzle and having a liquid discharge aperture formed therein, said spout being fiat and having two outer parallel plane surfaces, two plane parallel walls on both sides of said aperture, said walls being parallel with the plane surfaces of said spout, and means forming two oblique converging passages connected with said air inlet, each of said passages opening through an orifice upon said plane walls at a.
  • the obliquity of said passages and the position of their orifices being such that a portion of the air jet issuing from one of them meets the corresponding portion of the air jet coming out of the other orifice in front of the liquid discharge aperture, whereby the other portion of the air jet from both orifices strikes the corresponding outer plane surface of 10 the tubular spout.
