Abstract

Abstract A dual nozzle assembly for a hydrotherapeutic unit. The nozzle assembly includes a primary nozzle having a fixed orifice and combined with a secondary nozzle having a variable orifice. Both of the nozzles are located beneath the level of water in a tub or tank, and water under pressure is introduced into the inlet of the nozzle assembly. The water passing through the primary nozzle provides an aspirating action to draw air into the primary nozzle through a standpipe which extends above the water level. Air is mixed with the water and the aerated high pressure stream is discharged beneath the water level. By adjusting the variable orifice of the secondary nozzle, the amount of water directed through the primary nozzle can be varied to thereby vary the velocity of the water being discharged.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 188 words
A nozzle assembly for a hydrotherapeutic unit, comprising a supply conduit disposed in a tank containing water, one end of the supply conduit being connected to a source of water under pressure, a first outlet conduit connected to said supply conduit, a nozzle disposed within said first outlet conduit and having an inlet communicating with supply conduit and having an outlet of reduced diameter communicating with said tank whereby water is discharged from said nozzle into the tank, air supply means for supplying means to said first outlet conduit at a location adjacent the outlet of the nozzle whereby air is mixed with the water being discharged from the nozzle to provide a high pressure aerated stream of water, a second outlet conduit connected to said supply conduit and spaced from said first outlet conduit and communicating with said tank, valve means connected in said second outlet conduit, and manually adjustable means for varying the flow of water through said valve means to selectively vary the velocity of discharge of the water through the valve means and provide a secondary zone of water discharge through said valve means.
Claim 2
Dependent Claim 188 words
A nozzle assembly for a hydrotherapeutic unit, comprising a supply conduit disposed in a tank containing water, one end of the supply conduit being connected to a source of water under pressure, a first outlet conduit connected to said supply conduit, a nozzle disposed within said first outlet conduit and having an inlet communicating with supply conduit and having an outlet of reduced diameter communicating with said tank whereby water is discharged from said nozzle into the tank, air supply means for supplying means to said first outlet conduit at a location adjacent the outlet of the nozzle whereby air is mixed with the water being discharged from the nozzle to provide a high pressure aerated stream of water, a second outlet conduit connected to said supply conduit and spaced from said first outlet conduit and communicating with said tank, valve means connected in said second outlet conduit, and manually adjustable means for varying the flow of water through said valve means to selectively vary the velocity of discharge of the water through the valve means and provide a secondary zone of water discharge through said valve means.
Claim 3
Dependent Claim 50 words
The nozzle assembly of claim 1, wherein said valve means includes a fixed valve member having a first port and a movable valve member having a second port disposed to be moved into and out of registry with said first port to thereby control the flow through said valve member.
Claim 4
Dependent Claim 30 words
The nozzle assembly of claim 1, and including swivel means connected to the supply conduit means for mounting the supply conduit means for swivel movement with respect to the tank.
Claim 5
Dependent Claim 59 words
The nozzle assembly of claim 2, wherein said adjusting means includes a hand knob connected to said second valve member. 5. The nozzle assembly of claim 2, wherein said fixed valve member includes a pair of first ports disposed diametrically opposite each other and said movable valve member includes a pair of second ports disposed diametrically opposite each other.
Claim 6
Dependent Claim 23 words
The nozzle assembly of claim 5, wherein the diameter of the first ports is substantially equal to the diameter of the second ports.
Claim 7
Dependent Claim 185 words
A nozzle assembly for a hydrotherapeutic unit, comprising a vertical conduit adapted to be disposed in a tank containing water, the upper end of said vertical conduit being connected to a source of water under pressure, a first generally horizontal conduit connected to said vertical conduit, a first nozzle having an inlet connected to said first horizontal conduit and having an outlet communicating with said tank whereby water is discharged from said nozzle into the tank, air supply means for supplying air to said first horizontal conduit at a location adjacent the outlet of the first nozzle whereby air is mixed with the water being discharged from the nozzle to provide a high pressure aerated stream of water, a second generally horizontal conduit connected to said vertical conduit and spaced vertically from said first horizontal conduit, a second nozzle located in said second horizontal conduit, and adjusting means operably connected to said second nozzle for varying the flow of water through said second nozzle to selectively vary the velocity of discharge of the water through the nozzles and provide a secondary zone of water discharge.
Claim 8
Dependent Claim 185 words
A nozzle assembly for a hydrotherapeutic unit, comprising a vertical conduit adapted to be disposed in a tank containing water, the upper end of said vertical conduit being connected to a source of water under pressure, a first generally horizontal conduit connected to said vertical conduit, a first nozzle having an inlet connected to said first horizontal conduit and having an outlet communicating with said tank whereby water is discharged from said nozzle into the tank, air supply means for supplying air to said first horizontal conduit at a location adjacent the outlet of the first nozzle whereby air is mixed with the water being discharged from the nozzle to provide a high pressure aerated stream of water, a second generally horizontal conduit connected to said vertical conduit and spaced vertically from said first horizontal conduit, a second nozzle located in said second horizontal conduit, and adjusting means operably connected to said second nozzle for varying the flow of water through said second nozzle to selectively vary the velocity of discharge of the water through the nozzles and provide a secondary zone of water discharge.
Claim 9
Dependent Claim 19 words
The nozzle assembly of claim 7, wherein the axes of said first and second horizontal conduits are substantially parallel.
Claim 10
Dependent Claim 18 words
The nozzle construction of claim 8, wherein the second horizontal conduit is located beneath the first horizontal conduit.
