Abstract
Abstract A hydrotherapy method and apparatus for using available tap water supply pressure to mix fresh tap water, tub water, and air to discharge a water-air stream into a tub below the water surface. Energy derived from the tap water supply is used to concurrently translate a discharge nozzle along a path substantially transverse to the stream discharged from the nozzle.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
105 words
A method of discharging a water stream into a water pool for impacting a user's body, comprising the steps of: supplying a pressurized tap water flow; directing said tap water flow along a convergent path to develop a region of reduced pressure; communicating said reduced pressure region with said water pool to entrain a pool water flow with said tap water flow to produce a combined water flow; and discharging said combined water flow into said pool in a direction substantially parallel to the surface of said pool while concurrently moving said combined water flow in a direction substantially perpendicular to said direction of discharge.
Claim 2
Independent Claim
105 words
A method of discharging a water stream into a water pool for impacting a user's body, comprising the steps of: supplying a pressurized tap water flow; directing said tap water flow along a convergent path to develop a region of reduced pressure; communicating said reduced pressure region with said water pool to entrain a pool water flow with said tap water flow to produce a combined water flow; and discharging said combined water flow into said pool in a direction substantially parallel to the surface of said pool while concurrently moving said combined water flow in a direction substantially perpendicular to said direction of discharge.
Claim 3
Dependent Claim
77 words
The method of claim 1 wherein said step of discharging said combined water flow includes the step of directing said combined water flow through a discharge nozzle mounted for movement along a travel path and wherein said discharge nozzle discharges said combined water flow in a direction having a primary component extending substantially perpendicular to said travel path and a secondary component extending substantially parallel to said travel path for thrusting said nozzle along said travel path.
Claim 4
Dependent Claim
26 words
The method of claim 1 including the further step of mixing air with said combined water flow prior to said step of discharging into said pool.
