Abstract (en)
The invention relates to valves for apparatus for dispensing a liquid product (13) from a pressurised container (12) which is required to dispense an accurately metered quantity of the liquid product (13). The dispensing apparatus (10) comprises a metering valve (11) for use with the container (12) for pressurised liquid (13), the valve (11) comprising a valve body (14) defining a chamber having one or more inlets (20, 21, 22) for pressurised liquid (13) and an annular seal member (40) positioned around the valve body (14) and in sealing contact with an inner surface of the container (12). The seal member (40) comprises an annular inner section (41) providing a liquid flow path from the container (12) to one or more inlets (21, 22) providing support for an outwardly extending flexible outer flange section (42) which flexes to make sealing contact with the container (12). <IMAGE>
