There is a valve assembly for controlling the admission of a fluid such as air into a vehicle tyre or other pressure vessel. The assembly includes a housing (1) with a valve assembly (10) movable therein by a predetermined pressure in said vessel against a spring 5A. The valve member (10) is movable from a first position at which ports (14) of an inlet passage (13) in the housing (1) are open to fluid flow into the vessel to a second position at which the ports (14) are closed by the valve member (10). In use of the valve assembly when the valve member (10) is biased to the first position by the spring 5A the fluid can flow into the vessel until pressure therein reaches the predetermined pressure and the valve member (10) is moved to the second position to terminate flow into the vessel. The valve assembly also includes a low pressure indicating means comprising a transparent cap 3A with an opaque band (23) and a collar (8) movable with the valve member (10).
A valve assembly for controlling the admission of a fluid such as air into a vehicle tyre or other pressure vessel, said assembly including a housing with a valve member therein movable by a predetermined pressure in said vessel against a bias from a first position at which one or more ports of an inlet passage in said housing are open to fluid flow into said vessel to a second position at which said ports are closed by said valve member whereby in use of said valve assembly when said valve member is biased to said first position said fluid can flow into the vessel until pressure therein reaches said predetermined pressure and the valve member is moved to said second position to terminate flow into said vessel.
