    Abstract: A valve gasket for sealing a fluid dispenser device comprising a valve, in particular a metering valve, mounted on a fluid reservoir, said gasket being characterized in that it comprises an alloy of vulcanized ethylene vinyl acetate (EVA) and/or of butyl (IIR) or of vulcanized halobutyl (CIIR or BIIR) with one or more materials selected from the group constituted by polyoctene ethylene (POE), ethylene propylene (EP), ethylene propylene diene monomer (EPDM) and chloroprene rubber (CR), all of these materials being vulcanized.

    CPC classification number: B65D83/54

    Abstract: 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.

    Abstract translation: 一种用于分配流体，特别是分散在推进剂气体中的粉末的计量阀的阀垫圈，所述计量阀包括限定计量室的阀体和安装成在计量室中在静止位置之间滑动的阀杆 以及致动位置，所述阀杆与所述计量腔之间的密封由所述阀垫圈提供，所述阀体被固定在用于将所述阀组装到流体储存器上的固定盖中，所述阀垫圈设置有径向内侧 接触区域，阀杆在其上滑动，接触区域固定到刚性元件，使得当阀杆移动时，阀垫片的接触区域在其形状及其位置方面基本上保持不变，接触 区域具有至少部分地圆化的轮廓，以便减小阀垫片和阀杆之间的接触面积，刚性元件是固定盖的一体部分， 特别是其内径向边缘。
