VALVE FOR DISPENSING A FLUID PRODUCT AND DEVICE FOR DISPENSING A FLUID PRODUCT INCLUDING SUCH VALVE

摘要

The invention relates to a valve for dispensing a fluid product, that comprises a valve body (10) including a dosage chamber (20) and a valve member (30) sliding in said valve body (10) between a rest position and a dispensing position for selectively dispensing the content of said dosage chamber (20), said dosage chamber (20) being connected, during the rest position of the valve member (30) to a fluid product tank containing the product to be dispensed via a fluid flow passage (35, 35'), said valve member (30) including a radial bearing collar, and said fluid flow passage (35, 35') at said collar (320) extending at least partially inside said valve member (30) and/or said collar (320) for allowing the filling of the dosage chamber (20) by gravity when, in the rest position of the valve member (30), the valve is in an inverted position relative to the dosage chamber (20) provided under the tank, and or allowing the emptying of said dosage chamber (20) by gravity when, in the rest position of the valve member (30), the valve is in an upright position relative to the dosage chamber (20) provided above the tank.
