ABSTRACT:
A fluid manifold includes a housing having a first inlet and an outlet and a plurality of inlets intermediate the first inlet and the outlet which are provided with check valve action to prevent retrograde flow through the valved inlets, yet allow individual inlets to pass fluid when the fluid pressure in any individual inlet exceeds that of the interior of the chamber by a predetermined cracking pressure, and retrograde flow through the first inlet is controlled by a flapper portion which may be biased to an open position to allow unrestricted flow from the first inlet to the outlet or configured so as to be in sealing contact with a valve seat in order to preferentially inhibit flow.
