Abstract

The self-regulating jet pump is supplied with high pressure air through an inlet (11) connected to a nozzle (2). The nozzle has an annular outlet surrounding a projecting cone. The air issuing from the nozzle clings to the surface of the cone to form a small high velocity jet of circular cross-section which flows into the venturi duct. This high velocity jet sucks in air through the inlet and drives it through venturi ducts. The end venturi duct is attached to a flexible diaphragm. Any variation of the internal pressure deflects the diaphragm which regulates the relative positions of the venturi ducts and so regulates the outlet flow.
