A valve gasket for a metering valve serving to dispense a fluid, in particular a powder dispersed in a propellant gas, the metering valve including a valve body defining a metering chamber, and a valve rod mounted to slide in the metering chamber between a rest position and an actuating position, the sealing between the valve rod and the metering chamber being provided by the valve gasket, the valve body being fixed in a fixing cap serving to assemble the valve onto a fluid reservoir, the valve gasket being provided with a radially inside contact zone over which the valve rod slides, the contact zone being fixed to a rigid element so that, while the valve rod is moving, the contact zone of the valve gasket remains substantially unchanging in terms of its shape and of its position, the contact zone having a profile that is rounded at least in part, so as to reduce the area of contact between the valve gasket and the valve rod, the rigid element being an integral part of the fixing cap, and in particular the inside radial edge thereof.

Valve gasket for a metering valve

A fixing element ( ) for fixing a dispenser member ( ), such as a pump or a valve, to the neck ( ) of a container ( ) containing a substance to be dispensed, with a neck gasket ( ) being interposed, the neck gasket having an inner edge ( ) and an outer edge ( ) for providing sealing at the neck ( ) of the container ( ), the fixing element ( ) including a dispenser member receiving portion ( ) for receiving the dispenser member ( ) and a fixing portion ( ) for fixing to the neck ( ) of the container ( ), the fixing element ( ) being characterized in that it further includes a holding portion ( ) for receiving and holding the neck gasket ( ), the annular gasket ( ) being held in the holding portion ( ) of the fixing element ( ) at its inner edge ( ) only.

Low-friction valve stem

A metering valve having a metering chamber (7) and a valve rod (2) lying in a valve body (1). The valve rod includes an inlet channel (211, 214) which puts the metering chamber (207) into communication with a can (11) of substance under pressure when the valve rod is in a rest position. The inlet channel forms a siphon which prevents the valve from draining when it is the rightway up.
