ABSTRACT:
In a flow regulator, the illustrated and preferred embodiment incorporates an expandable inner valve structure formed of a resilient material which expands radially outwardly to controllably choke flow through the valve, the flow regulator positioned immediately adjacent to the encircling tubular sleeve. The tubular sleeve controllably passes gas flowing through the regulator at a rate dependent on the radial expansion of the inner valve. Moreover, the improved version disclosed herein incorporates a transverse support plate for the tubular sleeve and the inner valve structure centered thereon. The support plate is drilled with a number of passages which distribute the gas flowing through the tubular sleeve across the cross-section of the downstream connected pipe thereby spreading the flowing gas to reduce downstream turbulence.
