<p>A valve and low pressure indicator assembly for a pressurized container, particularly for a vehicle tire, comprises: (a) a tubular housing (12) having a downwardly facing seat (20) disposed in the container and a downwardly depending annular skirt (18) surrounding the seat and having an inside wall, (18a) with an outward taper away from the seat; (b) a valve poppet (28) cooperating with the seat; (c) spring means (40) biasing the valve poppet away from the seat, the spring means being overcomeable by air pressure within the container to close the poppet above a pre-established pressure; (d) an indicator piston (42) reciprocable in the housing and having an upper portion (42a) adapted to be seen and indicate low pressure; and (e) a flexbile disc-like baffle means (70) extending outward adjacent the valve poppet to assist in the closing action of the poppet and normally engaging the tapered wall. The flexible disc-like baffle means (70) helps to ensure proper seating of poppet (28) and maximum flow during fill.</p> |
