Abstract

A pressure-controlled valve comprising an elastic-walled conductor, such as a tube, with a flow-obstructing body within the conductor. Fluid flow through the conductor is controlled by expanding the elastic wall away from the flow-obstructing body to provide fluid flow paths and by contracting the elastic-wall of the conductor toward the body to close the flow paths. Expansion and contraction of the elastic-wall of the conductor is in response to the differential pressure between the inside and the outside of the conductor.
