Abstract:
A valve assembly comprising:a delivery tube having an inlet port at an inlet end and an outlet at an outlet end, an annular shoulder about the inlet port at the inlet end directed towards the outlet, a valve member comprising a sealing member, a support member and a securement member, the support member having an inner end and an outer end, the support member carrying the sealing member at the inner end and the securement member at the outer end, the valve member removably received in the delivery tube by the securement member being removably secured in the outlet with the sealing member biased by the support member into sealing engagement with the annular shoulder about the inlet port to seal the inlet port to fluid flow therethrough other than fluid flow under a pressure differential across the sealing member sufficient to deflect the sealing member towards the outlet away from sealing engagement with the annular shoulder, the delivery tube and its inlet port, annular shoulder and outlet are generally circular in cross-section about a common longitudinal axis extending from the inlet end to the outlet end, the sealing member comprising a circular sealing disc with a radius larger than a radius of the inlet port, the sealing disc having a circular central portion with an annular peripheral flange portion extending radially outwardly about the central portion, the inner end of the support member connecting to the central portion of the sealing disc, the annular flange portion of the sealing member being resilient and adapted to be resiliently deflected away from sealing engagement with the annular shoulder towards the outlet.
