ABSTRACT:
A flow control device is disclosed which includes a housing having a plate or partition oriented generally transverse to the fluid flow direction. The partition has a central opening and a plurality of flow passages disposed in a circular array about the opening. The device also includes a generally T-shaped elastomeric element having a stem received by the central opening in the partition and a disk-shaped flange projecting transversely from the stem. The flange has a lower, beveled, annular surface overlying the flow passages and defining with the partition a variable flow area. Variations in fluid pressure causes the beveled portion of the flange to deflect accordingly. The flow area is thereby varied so that the flow rate is maintained substantially constant irrespective of pressure variations.
