Abstract
A variable output nozzle for permitting the output of air or gas from the nozzle to be varied. The variable output nozzle includes a nozzle housing having a bore located therein, a spherical ball located within the bore for reciprocal movement within the bore and an aperture in the nozzle housing for supplying pressurized air or gas to the bore in the nozzle housing. A plurality of slots are also located in the nozzle housing and extend into the upper portion of the bore and the bottoms of at least some of these slots are located at different depths so that the volume of pressurized air or gas exiting the nozzle will vary as the spherical ball passes the bottoms of the slots. The variable output nozzle is particularly useful as a pneumatic pressure transducer nozzle.
