## Abstract

A fluid dispenser valve for assembling on a fluid reservoir, the valve comprising a valve body (10) containing a metering chamber (20), and a valve member (30) that is slidable in leaktight manner in said valve body (10) between a rest position and an actuated position, said valve containing an inlet passage (40) enabling said metering chamber (20) to be filled with fluid, said valve including a closure element (50) that co-operates with said inlet passage (40), said closure element (50) being movable between an open position in which said inlet passage (40) is open, and a closed position in which said inlet passage (40) is closed at least in part.

## Claims

### Claim 1

A fluid dispenser valve for assembling on a fluid reservoir, the valve comprising a valve body (10) containing a metering chamber (20), and a valve member (30) that is slidable in leaktight manner in said valve body (10) between a rest position and an actuated position, said valve containing an inlet passage (40) enabling said metering chamber (20) to be filled with fluid, said valve being characterized in that it includes a closure element (50) that co-operates with said inlet passage (40), said closure element (50) being movable between an open position in which said inlet passage (40) is open, and a closed position in which said inlet passage (40) is closed at least in part, said inlet passage (40) being closed in non-leaktight manner in the closed position of said closure element (50), such that the fluid contained inside the metering chamber (20) can, by gravity, slowly flow out of said metering chamber via said inlet passage (40) that is closed by said closure element (50).

### Claim 2 (depends on 1)

A valve according to claim 1, in which said closure element (50) is displaced by gravity between its open and closed positions.

### Claim 3 (depends on 1)

A valve according to claim 1, in which said flow rate in the closed position of the closure element is predeterminable.

### Claim 4 (depends on 1)

A valve according to claim 1, in which said inlet passage (40) is formed in the valve body (10).

### Claim 5 (depends on 4)

A valve according to claim 4, in which said closure element (50) is a sleeve that slides relative to the valve body.

### Claim 6 (depends on 4)

A valve according to claim 4, in which said closure element (50) slides over the outside of the valve body (10).

### Claim 7 (depends on 4)

A valve according to claim 4, in which said closure element (50) slides inside the valve body (10).

### Claim 8 (depends on 1)

A valve according to claim 1, in which said inlet passage (40) is formed in the valve member (30).

### Claim 9 (depends on 8)

A valve according to claim 8, in which said closure element (50) is a sleeve that slides about said valve member (30).

### Claim 10 (depends on 9)

A valve according to claim 9, in which said sleeve (50) is disposed in said metering chamber (20).

### Claim 11 (depends on 8)

A valve according to claim 8, in which said closure element (50) is an element that is movable inside said valve member (30).

### Claim 12 (depends on 11)

A valve according to claim 11, in which said movable element is a bead.

### Claim 13 (depends on 11)

A valve according to claim 11, in which said movable element is a lug.

### Claim 14 (depends on 1)

A fluid dispenser device including a fluid reservoir, the device being characterized in that it includes a valve according to claim 1.
