Abstract:
A valve gasket assembly configured for a metering valve serving to dispense a fluid, the metering valve having 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, said valve gasket assembly comprising:a fixing cap configured to secure the valve body and to assemble the valve onto a fluid reservoir; and a valve gasket configured to provide sealing between the valve rod and the metering chamber, said valve gasket provided with a radially inside contact zone configured to receive the valve rod in sliding contact, said contact zone being fixed to a rigid element so that, when the valve rod moves, said contact zone of said valve gasket remains substantially unchanging in terms of its shape and of its position, said contact zone having a profile that is rounded at least in part, so as to reduce the area configured to contact the valve rod, and wherein said rigid element is an integral part of said fixing cap.
