Title: Ralph H. Knauer and His Venturi Nozzle for Air Guns.
Introduction
Ralph H. Knauer was an inventor associated with Clifton, New Jersey, and Western Electric Company, Inc. His patent work includes an air-gun nozzle designed to increase airflow while reducing operating noise.
Latest Patents
Knauer’s listed patent, “Venturi Nozzle for Air Guns,” describes an elongated cylindrical tube with a restricted orifice that receives compressed air. The discharge end has a larger airflow area, allowing the air to expand after passing through the orifice. Apertures near the orifice draw ambient air into the tube through the Venturi effect, where it mixes with the expanding compressed air.
The patent explains that positioning the apertures at non-diametrically opposed locations and making them longer along the tube’s axis than they are wide around its circumference maximizes output airflow for a given compressed-air input. Tapering the aperture ends toward the receiving end further increases airflow and reduces noise. Knauer is credited with 1 patent.
Career Highlights
Knauer’s recorded patent is associated with Western Electric Company, Inc. It reflects an engineering focus on improving airflow efficiency and reducing noise in air-gun equipment.
Collaborations
William R. Rohrbach is identified as Knauer’s coworker. The available information does not specify whether Rohrbach collaborated on the patent.
Conclusion
Ralph H. Knauer’s patented Venturi nozzle combines air expansion and ambient-air entrainment to increase airflow while minimizing noise.
