Abstract
A valve assembly for an aerosol can comprises a valve conduit having an inlet, an outlet, a valve seat in the flow path between the inlet and the outlet, and a resilient mounting of a valve member that permits relative movement of the valve member relative to the valve conduit. The valve member further comprises a valve element that is movable to sealingly engaging the valve seat, and a stem projecting from the valve member through the outlet of the valve conduit. During the movement of the valve member relative to the valve conduit, the movable tapered sealing surface associated with the valve member is configured to engage and concentrically align with a tapered valve seat on the valve conduit to establish an effective seal against the valve seat.
