Abstract
An air entrainment spa nozzle having a jet of water which passes over an air entrainment port with the air entrainment port having a downstream structure which enhances the air entrainment. In one embodiment, the air enhancement structure is a ramp which extends in a downstream direction from the air entrainment port. In another embodiment, the air entrainment port projects or protrudes into the jet of water by a predetermined amount.
Claims9
In an underwater spa nozzle wherein a jet of water passes over an air entrainment port, the improvement for enhancing air entrainment comprising a ramp surface extending in a downstream direction from said air entrainment port.
In an underwater air entrainment spa nozzle wherein a jet of water passes over an air entrainment port, the improvement wherein said air entrainment port has a downstream structure which enhances the air entrainment.
In an underwater spa nozzle, a fluidic oscillator for oscillating a jet of water back and forth and an air entrainment port over which said jet of water flows, said air entrainment port having a downstream structure for enhancing air entrainment.
