Fluid valve with directional outlet jet of continuously changing direction

The combination of a valve body for a fluid nozzle with a control means for adjusting the effluent fluid flow pattern which comprises:

• a valve body for a fluid valve having a first fluid inlet means, said valve body defining a valve bore immediately downstream of said first fluid inlet means,
• a rotor chamber mounted for axial movement within said valve bore and defining radially offset fluid inlet aperture means for fluid communication with said first fluid inlet means,
• a rotor body defining a rotor bore mounted for rotary movement, within said valve bore, said rotor body being in fluid communication with said radially offset fluid inlet aperture means, and said rotor bore being in fluid communication with said first fluid inlet means,
• said control means including a shroud ring provided in said valve bore, and positioned to overly and block at least a portion of said radially offset fluid inlet aperture means in any of a series of positions of said axially moveable rotor chamber, and further positioned to permit unrestricted flow to said radially offset fluid inlet aperture means in a second position of said axially moveable rotor chamber, whereby fluid passes from said first fluid inlet means to both said rotor bore and to said radially offset fluid inlet aperture means in varying ratios depending upon the axial positioning of said rotor chamber, said varying ratios determining the extent of the directional forces impinging on said rotor body to thereby adjust the pattern of effluent fluid flow through said rotor bore, and
• a fluid outlet means in fluid communication with said rotor bore.

A fluid valve for discharging a directional outlet fluid stream of continuously changing direction comprising:

• a valve body having a first fluid inlet means and having a valve bore therethrough, said valve bore having a longitudinal axis and a fluid outlet means;
• an elongated rotor body mounted within said valve bore and having a rotor bore passing therethrough, said rotor body being mounted for movement within said valve bore to enable displacement of said rotor bore with respect to said longitudinal axis of said valve bore, said rotor bore having a rotor bore inlet and rotor bore outlet, said rotor bore inlet beng in fluid communication with said first fluid inlet means and said rotor bore outlet having its outer end communicating with said fluid means of said valve body;
• and
• a rotor chamber having fluid inlet port means in communication with said first fluid inlet means, said fluid inlet port means of said rotor chamber being radially offset with respect to said longitudinal axis of said valve bore, and said radially offset fluid inlet port means of said rotor chamber being in communication with said rotor body whereby at least a portion of fluid entering said first fluid inlet means initially passes into said radially offset fluid inlet port means of said rotor chamber and thence exerts external force on said rotor body to cause movement of said rotor body and displacement of said rotor bore with respect to said longitudinal axis of said valve bore, and whereby fluid also passes through said rotor bore inlet into said rotor bore, and into said fluid outlet means of said valve body, as a directional outlet stream of predetermined continuously changing direction, as determined by the displacement of said rotor bore;
• and
• said rotor chamber being provided with a control means to adjust the rate of movement of said rotor body by increasing or decreasing the amount of fluid entering said first fluid inlet means and conversely decreasing or increasing the amount of fluid entering said radially offset fluid inlet port means of said rotor chamber.
