Abstract
A presettable fluid flow regulator having a body in the form of an elongated sleeve of flexible material and a core within the sleeve having a recess of varying cross section on its outer surface along its length. A ring on the outside of the sleeve having an internal diameter slightly less than the outer diameter of the sleeve is used to squeeze the sleeve against the core to define a flow passage between the body and the sleeve. The volume of flow is determined by the longitudinal position of the ring along the sleeve.
Claims18
A presettable flow-regulator connectable between two fluid-carrying tubes, comprising:
- a core connectable at one end to one fluid tube and having a passageway for conducting the fluid therefrom to the outer surface of the core;
- a flexible sleeve having an open end receivable over said core and connectable at its opposite end to the other fluid tube;
- said core having an outer diameter slightly smaller than the inner diameter of the flexible sleeve and having a recess of varying cross-section formed in its outer surface and progressing axially of the core;
- and a ring having an inner diameter slightly smaller than the outer diameter of the flexible sleeve and receivable thereover, said ring being presettable along the length of the flexible sleeve to press the underlying portion thereof against the core at a selected cross-section of said recess to thereby regulate the flow of the fluid between the core and the flexible sleeve from one tube to the other.
