<p>A fluid dispenser valve comprising a valve body (10) containing a metering chamber (20), and a valve member (30) that slides in said valve body (10) between a rest position and a dispensing position, for selectively dispensing the content of said metering chamber (20), said metering chamber (20) being, in the rest position of the valve member (30), connected to a fluid reservoir containing the fluid to be dispensed via a fluid-flow passage (35, 35′), said valve member (30) including a radial support collar, said fluid-flow passage (35, 35′) passing, level with said collar (320), inside said valve member (30) and/or said collar (320), at least in part, so as to enable the metering chamber (20) to be filled by gravity when, in the rest position of the valve member (30), the valve is in an upsidedown position with the metering chamber (20) disposed below the reservoir, and so as to enable said metering chamber (20) to be emptied by gravity when, in the rest position of the valve member (30), the valve is in an upright position with the metering chamber (20) disposed above the reservoir.</p> |
