Abstract

The invention relates to a fluid valve comprising a movable flap ( 1 ) provided with a first wing ( 3 ) and a second wing ( 4 ), said valve also including a gasket ( 2 ) having an opening ( 5 ) for the passage of the fluid. At least one ( 3 ) of the aforementioned wings, known as the sealing wing, can seal the opening ( 5 ) in the gasket ( 2 ) at least partially when the flap ( 1 ) is in the closed position. According to the invention, the sealing wing ( 3 ) and the other wing ( 4 ) are positioned on each side of the gasket ( 2 ) when the flap is in the closed position and the flap comprises an intermediate area ( 6 ) connecting the first ( 3 ) and second ( 4 ) wings and extending through the opening in the gasket ( 6 ).

First claim

The invention claimed is:

1. A fluid circulation valve comprising:
a mobile flap equipped with a first wing and with a second wing, wherein one of the first wing or the second wing is referred to as the shutoff wing, and the other of the first wing or the second wing is referred to as the other wing; and
a single seal, said single seal having an opening for the passage of the fluid,
wherein the shutoff wing is configured, at least in part, to shut off said opening in the single seal when the mobile flap is in a closed position,
wherein said shutoff wing is provided on one side of the single seal and said other wing is provided on the other side of the single seal when the mobile flap is in the closed position,
wherein said mobile flap comprises an intermediate zone connecting said first wing and said second wing,
wherein the intermediate zone passes through said opening in the single seal,
wherein said single seal comprises a planar zone, the planar zone of the single seal comprising:
a surface against which a planar bearing face of said shutoff wing comes to bear when the mobile flap is in the closed position; and
an opposite surface against which a planar bearing face of the other wing comes to bear when the mobile flap is in the closed position,

wherein said opening for the passage of the fluid provided in the single seal is positioned in the region of said planar zone,
wherein said bearing face of the shutoff wing and said bearing face of the other wing extend in two parallel planes distant from one another by a dimension corresponding to the thickness of only the single seal in said planar zone,
wherein the mobile flap rotates about a pivot shaft, and
wherein the parallel planes of the bearing face of the shutoff wing and the bearing face of the other wing do not intersect the shaft.

2. The valve as claimed in claim 1 , wherein the other wing of the mobile flap has a surface on the opposite side to the corresponding planar bearing face, the intermediate zone has an inclined plane, and the inclined plane extends from the bearing face of the shutoff wing to the surface on the opposite side to the planar bearing face of the other wing such that the inclined plane directly connects the shutoff wing to the other wing.

3. The valve as claimed in claim 1 , further comprising, near the intermediate zone of the mobile flap, an axis about which the mobile flap is articulated, which is off-centered with respect to said flap, and in which valve, in a direction of the axis of articulation of the mobile flap, said shutoff wing has a dimension extending on either side beyond the dimension by which the intermediate zone extends, at least in the region of a zone of connection between said intermediate zone and said shutoff wing.

4. The valve as claimed in claim 1 , wherein said single seal has a boss along a part of the passage opening which part is provided facing the other wing of the mobile flap when the mobile flap is in the closed position, said boss being configured to be compressed by said other wing when the mobile flap is in the closed position.

5. The valve as claimed claim 1 , further comprising a body defining a main duct and an auxiliary duct for the flow of the fluid, the auxiliary duct opening into said main duct, wherein said mobile flap moves between the closed position for preventing communication between the two ducts and an open position that allows communication between said ducts at a fluid passage aperture, said opening in the single seal allowing the fluid to pass from one of the main duct or the auxiliary duct into the other of the main duct or the auxiliary duct.

6. The valve as claimed in claim 5 , wherein said first wing allows closure of said passage aperture when the mobile flap is in the closed position, and said second wing allows closure of said main duct at least partially when the mobile flap is in the open position, said first wing being said shutoff wing and said second wing being said other wing.

7. The valve as claimed in claim 6 , wherein said single seal has a blind zone situated facing said other wing when the mobile flap is in the closed position.

8. The valve as claimed in claim 7 , wherein said body comprises a housing for a flap actuating motor, said body being configured to define an air gap between said blind zone of the single seal and said housing.

9. The valve as claimed in claim 7 , wherein the blind zone of the single seal is a portion through which the fluid cannot pass through.

10. The valve as claimed in claim 1 , wherein the valve comprises a body defining a fluid flow duct, wherein said mobile flap moves between said closed position to prevent the circulation of the fluid in the fluid flow duct, and an open position allowing the fluid to circulate in the duct, wherein said single seal is positioned transversely to said fluid flow duct so that said opening in the single seal allows the fluid to pass along the fluid flow duct, when the mobile flap is in the open position.

11. The valve as claimed in claim 10 , wherein said opening extends facing the shutoff wing and said other wing when the mobile flap is in the closed position.

12. The valve as claimed in claim 10 , wherein the single seal is held in said body by a sleeve.

13. The valve as claimed in claim 1 , wherein the surface and the opposite surface of the planar zone are planar in shape such that the planar zone of the single seal is planar in shape.

14. A fluid circulation valve comprising:
a mobile flap equipped with a first wing and with a second wing, wherein one of the first wing or the second wing is referred to as the shutoff wing, and the other of the first wing or the second wing is referred to as the other wing;
a single seal, said single seal having an opening for the passage of the fluid; and
a body defining a main duct and an auxiliary duct for the flow of the fluid, the auxiliary duct opening into said main duct, wherein said mobile flap moves between a closed position for preventing communication between the two ducts and an open position that allows communication between said ducts at a fluid passage aperture, said opening in the single seal allowing the fluid to pass from one of the main duct or the auxiliary duct into the other of the main duct or the auxiliary duct,
wherein said first wing allows closure of said passage aperture when the mobile flap is in the closed position, and said second wing allows closure of said main duct at least partially when the mobile flap is in the open position, said first wing being said shutoff wing and said second wing being the other wing,
wherein said shutoff wing is provided on one side of the single seal and said other wing is provided on the other side of the single seal when the mobile flap is in the closed position,
wherein said mobile flap comprises an intermediate zone connecting said first wing and said second wing,
wherein the intermediate zone passes through said opening in the single seal,
wherein said single seal comprises a planar zone, the planar zone of the single seal comprising:
a surface against which a planar bearing face of said shutoff wing comes to bear when the mobile flap is in the closed position; and
an opposite surface against which a planar bearing face of the other wing comes to bear when the mobile flap is in the closed position,

wherein said opening for the passage of the fluid provided in the single seal is positioned in the region of said planar zone,
wherein said bearing face of the shutoff wing and said bearing face of the other wing extend in two parallel planes distant from one another by a dimension corresponding to the thick
