Abstract: An aerosol metering valve (20) comprising: a valve body (21) containing a metering chamber (25) defined between an upper gasket (251) and a lower gasket (252); a valve member (30) that slides in leaktight manner against said upper and lower gaskets (251, 252) in said metering chamber (25); said metering chamber (25) including at least one movable element (100) that moves freely in said metering chamber (25), said at least one movable element being of shape that is substantially spherical, such as a ball.

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 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 u

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 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.
