The invention will be described in more detail below with reference to two embodiments illustrated by seven figures.
In the drawings:
While this invention may be embodied in many different forms, there are described in detail herein a specific preferred embodiment of the invention. This description is an exemplification of the principles of the invention and is not intended to limit the invention to the particular embodiment illustrated
Components which match each other in the different figures and both embodiments are given like reference figures.
The nozzle channel, the passage orifice 16 of which can be seen in the view of
Adjacent to the second channel portion, there is a third channel portion which is confined by two lateral surfaces 22 which smoothly pass over into a lateral surface 18 each of the second channel portion, and two bordering surfaces 24 which are disposed to be approximately parallel to the bordering surfaces 20 of the second channel portion, but are disposed at a lateral distance therefrom and are offset outwardly. Because of the described arrangement of the lateral and bordering surfaces, the nozzle channel continuously widens in the area of the second and third channel portions, proceeding from the passage orifice 16 in the direction of flow. The third channel portion opens into the level outer surface 10 so that the nozzle channel terminates altogether on this outer surface.
The two bordering surfaces 20 of the second channel portion define a step between the second and third channel portions.
The lateral surfaces 22 of the third channel portion are substantially wider than are its bordering surfaces 24 so that the third channel portion is of an approximately rectangular, extended cross-section. The lateral surfaces 22 of the third channel portion extend perpendicularly to the longer edge of the level outer surface 10.
The perspective sectional representation of
This view allows to recognize the lateral surfaces 18 and 22 and the bordering surfaces 20 and 24 of the second and third channel portions. An edge of the passage orifice 16 can be identified at 30. This edge is joined by a flat bottom surface 32 of the second channel portion that is disposed in parallel with the outer surface 10. Another flat bottom surface 34 is located between the bordering surfaces 20 and 24 of the second and third channel portions. A first channel portion 26 is located in the direction of flow below the passage orifice 16. The channel has two lateral surfaces facing each other, one of which can be seen having the reference
Also provided with a cylindrical cross-section is a fourth channel portion 38. This fourth channel portion 38 serves for introducing the medium to be sprayed and smoothly passes over into the first channel portion.
The spray nozzle assembly of
This cruciform arrangement can also be recognized in
Shown in a phantom line are the two flat bottom surfaces 32 which also adjoin the passage orifice 16 and extend in a direction perpendicular to the narrow cross-sectioned surface 36. The two first flat bottom surfaces 34 and the bordering surfaces 20 disposed in a circle segment fashion can be seen as well. The circle designated 40 indicates the inner circumference of the cylindrical fourth channel portion 38.
In
As a further particularity, on either side of the passage orifice 16, there is a web 46 projecting from a first portion 42 of the narrow cross-sectioned surface 36 which extends into the first channel portion. Each web 46 runs in the direction of one of the two lateral surfaces 18 of the second channel portion. Because of the specific configuration of the narrow cross-sectioned surface with the webs and inclined portions 44, a vortex is achieved for the medium to be sprayed in the area of the first channel portion before it flows through the passage orifice 16.

For a better comprehension, the second embodiment is schematically illustrated once more in a perspective view in
The above disclosure is intended to be illustrative and not exhaustive. This description will suggest many variations and alternatives to one of ordinary skill in this art, All these alternatives and variations are intended to be included within the scope of the claims where the term “comprising” means “including, but not limited to”. Those familiar with the art may recognize other equivalents to the specific embodiments described herein which equivalents are also intended to be encompassed by the claims.
Further, the particular features presented in the dependent claims can be combined with each other in other manners within the scope of the invention such that the invention should be recognized as also specifically directed to other embodiments having any other possible combination of the features of the dependent claims. For instance, for purposes of claim publication, any dependent claim which follows should be taken as alternatively written in a multiple dependent form from all prior claims which possess all antecedents referenced in such dependent claim if such multiple dependent format is an accepted format within the jurisdiction (e.g. each claim depending directly from claim 1 should be alternatively taken as depending from all previous claims). In jurisdictions where multiple dependent claim formats are restricted, the following dependent claims should each be also taken as alternatively written in each singly dependent claim format which creates a dependency from a prior antecedent-possessing claim other than the specific claim listed in such dependent claim below.
This completes the description of the preferred and alternate embodiments of the invention. Those skilled in the art may recognize other equivalents to the specific embodiment described herein which equivalents are intended to be encompassed by the claims attached hereto.
