ABSTRACT:
A venturi nozzle for air guns includes an elongated, cylindrically shaped tube having a restricted orifice in a compressed air receiving end thereof through which compressed air is passed into a discharge end thereof. The air flow area of the discharge end of the tube is greater than the air flow area of the orifice to allow expansion of the air exiting the orifice in a region of the discharge end of the tube adjacent the orifice. Apertures formed through the tube in the discharge end thereof adjacent the orifice permit ambient air to be drawn by venturi effect into the tube and to be discharged with the expanded air out of the discharge end of the tube. It has been discovered that when the apertures are positioned around the circumference of the tube at nondiametrically opposed positions, and have a length along the axis of the tube which is greater than the width of the apertures around the circumference of the tube, the volume of air output from the discharge end of the nozzle is maximized for a given volume of compressed air input to the receiving end of the nozzle. Furthermore, it has also been found that when the ends of the apertures along the lengths thereof are tapered at an acute angle relative to the axis of the tube toward the receiving end thereof, the volume of air output from the discharge end of the nozzle is further maximized and the noise generated by air passing through the nozzle is minimized.
