摘要： A one-way valve, comprising a cylindrical outer sleeve, having an inner surface and having an inlet end and an outlet end; and a plurality of flexible leaflets, fixed to the inner surface of the sleeve and extending radially inward therefrom, which leaflets assume a fully-open position when a sufficiently greater fluid pressure is applied to the inlet end of the sleeve than to the outlet end, and a closed position when a sufficiently greater fluid pressure is applied to the outlet end of the sleeve than to the inlet end, and wherein when the pressures applied to the inlet and outlet ends of the sleeve are substantially equal, the leaflets assume a partially-open position, intermediate between said closed and fully-open positions of the leaflets.
