Patent ID: 7735522

Claim:
A flow control device comprising: (a) a housing; (b) a first fluid pathway formed in said housing, said first fluid pathway containing a fluid at a static pressure and having a first end having a fluid inlet and a second closed end; (c) a second fluid pathway formed in said housing in communication with and located proximate said first fluid pathway, said second fluid pathway having a first end having a fluid inlet and a second end having a fluid outlet, said second fluid pathway containing a fluid flow; (d) a yieldably deformable membrane disposed between said first and second fluid pathways; and (e) flow rate stabilization means disposed within said second fluid pathway for achieving flow rate stabilization there within by providing viscosity dependent resistance to fluid flow along said fluid pathway, said means comprising an obstacle disposed within said second fluid pathway, said obstacle being constructed and arranged to produce an eddy within the fluid flowing along said second fluid pathway.
