Constant flow rate pressure regulator

摘要

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.

1. A pressure regulating constant flow rate valve, comprising:
(a) a body having an outlet and an outlet, the body housing a cage and an elastomeric sleeve; (b) the cage comprising an elongated and generally tubular body; a star-shaped polygonal cross-section; the cage further comprising an open end and a closed end, the generally tubular body having inwardly curved wall sections and outwardly curved wall sections forming a plurality of axially-extending channels running the length of the generally tubular body; (c) the elastomeric sleeve further comprising an elongated and generally conical shape; the elastomeric sleeve being received within the cage, the sleeve having a wide end and a narrow end, wherein the wide end of the sleeve is supported at the open end of the elongated cage, and wherein flow is guided to travel through the elastomeric sleeve from the wide end to the narrow end; and wherein flow is reversed by the closed end of the elongated cage; and wherein flow is then again reversed by the wide end of the elastomeric sleeve to continue traveling between the cage and the constant flow rate valve body in the original direction of flow.
