Air distribution valve for pivoting in two directions
First Claim
1. An air distribution valve for selectively directing a stream of pressurized air from a feed conduit to one of at least three outlet conduits;
- said air distribution valve comprising;
a) a base having at least three outlet openings extending through said base each in communication with one of said outlet conduits;
b) an outer gimbal ring mounted in spaced relation to said base;
c) an inner gimbal ring pivotally mounted within said outer gimbal ring and pivotal about a first axis; and
d) a flow directing nozzle pivotally connected at a first end thereof to said inner gimbal ring and pivotal about a second axis;
said second axis intersecting and extending perpendicular to said first axis such that said nozzle is selectively advanceable into alignment with each of said outlet openings in said base;
said nozzle is connectable at said first end thereof to said feed conduit by a flexible conduit.

Abstract
An air distribution valve comprises a gimbal mounted flow directing nozzle connected to a feed conduit and selectively and pivotally advanceable about at least two intersecting and perpendicular axes into alignment with one of four outlet openings in a base plate each opening to an outlet conduit. The gimbal includes an outer gimbal ring supported in horizontal alignment above the base plate and an inner gimbal ring pivotally mounted to and inside the outer gimbal ring and rotatable about a first axis. The flow directing nozzle is pivotally mounted on mounting arms pivotally connected to the inner gimbal ring and pivotal about a second axis which intersects and extends perpendicular to the first axis. When used in a wave generating system, each outlet conduit communicates with one of four caissons at one end of the wave pool for selectively delivering pressurized air to the caisson from a centrifugal fan to force water out of the caissons in a selected order to create a desired wave pattern.
