FLOW REGULATOR

摘要

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.
