Abstract: A fluid dispenser valve having a valve body (10) containing a metering chamber (20), and a valve member (30) that is slidable in the valve body (10) between a rest position and a dispensing position so as to dispense the contents of the metering chamber (20) selectively. The valve member (30) is urged resiliently towards its rest position by a spring (8) that co-operates firstly with the valve body (10) and secondly with a radial collar (320) of the valve member (30), the radial collar (320) being of a shape that is polygonal, the vertices (325) of the polygon being substantially rounded.

Abstract: A ring for disposing around a valve body of an aerosol dispenser valve that is mounted by a fastener element, such as a crimpable capsule, on a reservoir containing substance to be dispensed, the ring having an outer portion and an inner portion that cooperate with the valve body, and the outer portion having a deformable axial wall portion that extends towards the bottom of the reservoir and that is capable of deforming elastically in a radially-inward direction.

Abstract: A metering valve for dispensing fluid, the metering valve having a valve body (10), a metering chamber (20), and a valve member (30) that is slidable in the valve body (10) so as to dispense the fluid contained in the metering chamber (20). The wall (27) of the metering chamber (20) is curved, at least in part, in axial section.

Abstract: A ring (10) for disposing around a valve body (21) of an aerosol dispenser valve (20) that is mounted by means of a fastener element (50), such as a crimpable capsule, on a reservoir (1) containing substance to be dispensed, said ring (10) being characterized in that it comprises at least an outer portion (15) and an inner portion (11, 11?) that co-operates with said valve body, said outer portion (15) comprising a deformable axial wall portion (16) that extends towards the bottom of the reservoir and that is capable of deforming elastically in a radially-inward direction.

Abstract: Fluid product dispensing valve, comprising a valve body (10), a valve stem (20) moving in said valve body (10) between a rest position and a dispensing position, and an annular ring (30) mounted around said valve body (10), characterised in that said annular ring (30) is attached to said valve body (10), said attachment being substantially radially non-clamping onto said valve body (10), said annular ring (30) comprising an axial edge that is proximal with respect to outlet orifice of said valve stem (20), said annular ring (30) comprising one or more attachment means (35) co-operating with the valve body (10) and provided on or close to said proximal radial edge.

Abstract: A metering valve for dispensing fluid, the metering valve comprising a valve body (10), a metering chamber (20), and a valve member (30) that is slidable in said valve body (10) so as to dispense the fluid contained in the metering chamber (20.), the wall (27) of said metering chamber (20) being curved, at least in part, in axial section.

Abstract: A fluid dispenser valve comprising a valve body (10) and a valve member (20) that is slidable in said valve body (10) between a rest position and a dispensing position, said valve member (20) including a dispenser orifice (25), said valve including an axial guide element (15) that co-operates with a guided portion (29) of the valve member (20), said guided portion (29) being remote from said dispenser orifice (25).

Abstract: The inventive control valve for fluid products is mounted on a reservoir containing said fluid products, comprises a valve body (10) and a metering chamber (20) and is provided with a first valve element (30) for dispensing products contained in the metering chamber (20) and a second valve element (40) for filling said metering chamber (20). The invention is characterised in that said first and second valve elements (30, 40) are actuated separately during the operation of the control valve.
