Embodiment Construction

[0037] In the following, the same reference numerals are used to denote on the one hand the first fluid jet and the passage in which it flows, and on the other hand the second fluid jet or regulating jet and the passage in which the second fluid jet flows. corresponding to the second pipeline.

[0038] figure 1 A schematic diagram representing a method of controlling a jet according to the invention.

[0039] The first fluid jet to be controlled is conveyed via the channel 10 and interacts with the second fluid jet from the second duct 21 to obtain a resulting fluid jet 1 whose direction and / or opening angle are the same as in the absence of the second fluid jet. In the case of fluid jets the jet exiting the main outlet opening 11 is different.

[0040] The device comprises a passage 10 enabling a first fluid jet to be sent to a main output opening 11 .

[0041] At least one second duct 21 for injecting a second fluid jet opens into the channel 10 via a second opening 31 . ...

Abstract

The invention relates to an apparatus for injecting at least one jet of fluid, in which the direction and / or opening of at least one of the jets may be variable, comprising means of injecting at least one main fluid jet, means for injecting at least one secondary fluid jet, and means for causing at least one main fluid jet to interact with at least one secondary fluid jet and producing a fluid jet resulting from this interaction whose direction and / or opening are variable; as well as the associated method; and the uses of these.

Description

technical field [0001] The present invention relates to an injection device enabling to vary the direction and / or ouverture of a fluid jet, such as an air or oxygen jet, a nitrogen jet, a gaseous fuel or other gaseous liquid or solid fuel jet, which resulting from the interaction between the first fluid jet and at least one second fluid jet. The invention relates in particular to such a spray gun. [0002] The invention also relates to the use of said spraying device for changing the direction and / or opening angle of a fluid jet, eg in contact with a surface and in particular above a load. It also relates to a spraying method in which the user changes the direction and / or opening angle of at least one fluid jet. Background technique [0003] It is known from EP-A-0545357 to change the direction of the atomizing jet by gas flow: (1) the material to be atomized is passed through an atomizing passage with a constant cross-section part and a flared downstream part, (2) through...
