1. An improved nozzle assembly comprising, in combination:

  • a bearing member having a tubular sidewall closed at one end and open at the opposite end, said tubular sidewall defining a fluid passageway and having a distribution opening formed in said sidewall for allowing fluid entering said passageway via the open end to flow outwardly through said sidewall;

    a rotor sleeve disposed for rotation about said bearing member and radially spaced therefrom defining an annular chamber therebetween, said rotor sleeve having a plurality of discharge orifices formed through said sleeve and communicating with said annular chamber, said rotor sleeve including first and second annular flange members attached to said sleeve at opposite end portions thereof, respectively, said first and second annular flange members projecting radially inward toward said bearing member and radially spaced therefrom; and

    ,first and second annular shoulder members attached to said bearing member on opposite end portions thereof, respectively, said first and second annular shoulder members being axially spaced from said first and second annular flange members, respectively, the axial spacings between the bearing shoulders and sleeve flanges defining first and second radially extending, annular flow passages, and said radial spacings between the annular flanges and said bearing member defining first and second axially extending annular flow passages, each axially extending annular flow passage being in communication with said annular chamber and one of said radially extending flow passages, said annular flanges and shoulder members limiting axial and radial movement of said rotor sleeve relative to said bearing member while permitting flow of pressurized fluid from said rotor chamber through said first and second radial flow passages simultaneously with the flow of pressurized fluid from said rotor chamber through said discharge orifices, whereby pressurized fluid flowing through said rotor chamber defines a radial fluid bearing and pressurized fluid flowing through said first and second radially extending flow passages defines first and second axial fluid bearings.
