ABSTRACT:
A low actuation pressure, unidirectional flow valve comprising a housing including a fluid flow passage extending therethrough which defines first and second sections. Disposed within the housing between the first and second sections is a valve member. The valve member comprises an annular ring portion having a disc portion disposed therewithin. Extending between the ring and disc portions are at least two spirally shaped connecting arm portions. The ring, disc and connecting arm portions define at least two side openings. The valve member is movable between a closed position wherein the disc portion covers and seals the first section of the flow passage, and an open position wherein the disc portion is separated from the first section and fluid flows from the first section to the second section via the side openings.
