Abstract

Constructive arrangement applied in an electrostatic spray nozzle for aircraft and helicopters, equipped with electrode insulation fins, a diffuser core with a dosing disc and a fan dosing tip with regulation for a conical jet and flat jet.

Claims

1- Constructive arrangement applied to electrostatic spray nozzles for agricultural aircraft and helicopters comprising: a cylindrical body (1) containing an anti-drip system (15) said cylindrical body (1) having a thread (2) at the end connecting with the spray bar (not shown), at the other end, the spray nozzle itself (3) being that just below the thread (2) there is the projection (4) to thread the spray nozzle on the spray bar, an extension in the shape of an “L” (5) that protrudes from the threaded end (2) containing in the intermediate region a plurality of fins (6) and in the distal portion to the thread (2) a terminal (7), where the induction ring (8) is fastened by means of screws (9) with the high voltage cable.

2- Constructive arrangement according to claim 1 characterized in that the constructive arrangement allows the use of an extensive tip (10), where the induction ring (11) is further away from the cylindrical body (12).

3- Constructive arrangement according to claim 1 characterized by having a variation with the use of the fan tip (13).

4- Constructive arrangement according to claim 1 characterized by having an assembly using an induction ring in the form of a multi-perforated cylinder (14); a cylinder without perforations (15) and; an assembly of the fins in pairs facing each other (16).

Description

DESCRIPTION OF THE DRAWINGS

[0010] The characterization of the present utility model is made by means of drawings representative of the constructive arrangement applied in an electrostatic spray nozzle for aircraft and helicopters, in such a way that the product can be fully reproduced by appropriate technique, allowing full characterization of the functionality of the object claimed.

[0011] Based on the figures that express the best or preferential form of realizing the product now idealized, the descriptive part of the report is based, through a detailed and consecutive numbering, where it clarifies aspects that may be implied by the adopted representation to clearly determine the protection now sought.

[0012] These figures are merely illustrative and may present variations, as long as they do not run away from what was initially claimed.

[0013] This is the description of the drawings:

[0014] FIG. 1—shows a perspective and frontal view of the standard spray nozzle arrangement;

[0015] FIG. 2—shows a perspective and frontal view of the standard spray nozzle arrangement;

[0016] FIG. 3—shows a perspective and frontal view of the proposed spray nozzle arrangement with variation using a ceramic nozzle;

[0017] FIG. 4—shows a perspective and frontal view of the proposed spray nozzle arrangement with variation using a ceramic nozzle;

[0018] FIG. 5—shows perspectives of the proposed arrangement using the fan tip;

[0019] FIG. 6—shows perspectives of the proposed arrangement using the fan tip;

[0020] FIG. 7—shows the front view of a variation of the proposed construction arrangement, where the induction ring is in the shape of a multi-pierced cylinder;

[0021] FIG. 8—shows the frontal view of a variation of the proposed construction arrangement, where the fins of the extender are arranged in pairs facing each other; and

[0022] FIG. 9—shows the front view of a variation of the proposed construction arrangement, where the induction ring is in the shape of a cylinder.

DETAILED DESCRIPTION OF THE INVENTION

[0023] A preferred embodiment of the utility model employs a cylindrical body (1) containing an anti-drip system (15); said cylindrical body (1) having a thread (2) at the end connecting with the spray bar (not shown), at the other end, the spray nozzle itself (3); being that just below the thread (2) there is the projection (4) to thread the spray nozzle on the spray bar, an extension in the shape of an “L” (5) that protrudes from the threaded end (2); containing in the intermediate region a plurality of fins (6) and in the distal portion to the thread (2) a terminal (7), where the induction ring (8) is fastened by means of screws (9); these screws hold the high voltage cable (not shown).

[0024] The constructive arrangement allows the use of an extensive tip (10), where the induction ring (11) is further away from the cylindrical body (12).

[0025] Another variation occurs with the use of the fan tip (13) that allows flat- type electrostatic spraying.

[0026] Also, assembly is possible using an induction ring in the form of a multi-perforated cylinder (14), a cylinder without perforations (15) and an assembly of the fins in pairs facing each other (16).
