Abstract
The automatically deformable nozzle regulator described herein is for use in a venturi pump. The automatically deformable nozzle regulator automatically adjusts its output area as needed to provide an increased suction force at a venturi pump inlet. The nozzle regulator includes an outer tubular cylinder and an inner tubular cylinder, concentrically arranged, and an inlet section join the two cylinders at one end. The nozzle regulator is constructed of a flexible material, such that when a constricting force is applied an output area of the nozzle regulator is decreased. Fluid backpressure at the nozzle regulator caused by obstructions at the pump inlet or the head at the outlet cause backpressure and the resultant constricting force. Because the nozzle is deformable, the output area is reduced, thereby increasing suction force at the inlet to remove the obstruction and increased velocity at the outlet to increase the head at the outlet.
