Abstract
A flow valve that maintains a constant flow valve despite varying pressures at its inlet, comprising: (a) an elongated cage with alternating axially-extending pockets and ridges on its inner surface; and (b) an elongated generally conical shaped elastomeric sleeve received within the elongated cage; wherein the sleeve flexes outwardly at higher pressures, thereby decreasing the size of the flow channel between the sleeve and cage, thereby restricting flow to maintain constant flow valve despite varying inlet pressures.
