## Abstract

The invention relates to a fluid valve comprising: a body (50) defining a fluid flow duct (60), and a flap (1) that can move between a closed position preventing the fluid from flowing through the duct and an open position allowing the fluid to flow through the duct. According to the invention, the valve also comprises a joint (2) having at least one opening for the passage of the fluid, and the aforementioned flap can close the opening(s) (5) in the joint when in the closed position.

## Claims

### Claim 1

A fluid circulation valve comprising:
a body defining a fluid flow duct;
a flap able to move between a closed position, preventing circulation of the fluid in the duct, and an open position, allowing the fluid to circulate in the duct; and
a seal having at least one opening for the passage of the fluid, said flap being designed to be able to close said opening or openings in the seal when it is in the closed position.

### Claim 2 (depends on 1)

The valve as claimed in claim 1, wherein said flap is equipped with a first wing and with a second wing, said first and second wings being provided one on either side of the seal when the flap is in the closed position, said flap comprising an intermediate zone connecting said first wing and said second wing that passes through said opening in the seal.

### Claim 3 (depends on 2)

The valve as claimed in claim 2, wherein said opening extends facing said first and second wings when the flap is in the closed position.

### Claim 4 (depends on 1)

The valve as claimed in claim 1, wherein the seal is held in said body by a sleeve.

### Claim 5 (depends on 4)

The valve as claimed in claim 4, wherein said body defines a stop for said seal and said sleeve is configured to hold said seal pressed against said stop.

### Claim 6 (depends on 5)

The valve as claimed in claim 5, wherein said stop has a planar annular surface, provided in a plane transverse to a longitudinal axis of said duct, and said seal has a flat peripheral edge provided to press against said annular surface of the stop.

### Claim 7 (depends on 4)

The valve as claimed in claim 4, wherein said body has a cylindrical bore able to accept said sleeve.

### Claim 8 (depends on 4)

The valve as claimed in claim 4, wherein the sleeve is positioned on the other side of said seal with respect to an axis of articulation of the flap, which axis is off-centered with respect to said flap.

### Claim 9 (depends on 1)

The valve as claimed in claim 1, further comprising a drive shaft that drives the flap about an axis of articulation, and in which the flap comprises two bushings able to accept said shaft.

### Claim 10 (depends on 10)

The valve as claimed in claim 10, further comprising at least one bearing guiding the rotation of the shaft, provided in a housing for the passage of said shaft which is formed in said body of the valve, said bearing protruding into the duct.
