A pipe joint assembly, comprising: an adjustable pipe joint including (A) a one-piece, hollow sleeve extending along a longitudinal axis between opposite end faces and having a pair of generally ball-shaped end portions spaced longitudinally apart of each other, and a cylindrical central portion intermediate, and integral with, the ball-shaped end portions, each ball-shaped end portion having an outer diameter as considered along a transverse axis normal to the longitudinal axis, said outer diameters of the ball-shaped end portions being different in magnitude, said ball-shaped end portions and said central portion together bounding an internal fluid flow passage that extends along the longitudinal axis between the end faces of the sleeve; (B) inlet connector means for connecting one of the ball-shaped end portions to a fluid feed means, said inlet connector means including (i) an annular, hollow, inlet outer member of rigid material and extending along a first axis and circumferentially surrounding said one ball-shaped end portion, said inlet member having an annular lip extending radially inwardly of the first axis to bound a first circular opening having a diameter smaller than the outer diameter of said one ball-shaped end portion and greater than the outer diameter of said other ball-shaped end portion, said lip having a first, concave, inner circumferential surface, (ii) an annular, hollow, inlet locking ring mounted entirely within the inlet member and having a first, concave, inner, circumferential wall which, together with the first, inner, circumferential surface of said lip, form a generally spherical first socket for rotatably receiving said one ball-shaped end portion to orient said first axis in a range of inclination angles relative to said longitudinal axis, said first, concave, inner, circumferential wall extending substantially to the end face of said one ball-shaped end portion to increase the range of the inclination angles, and (iii) an inlet seal mounted in sealing engagement among the inlet member, the inlet locking ring and said one ball-shaped end portion; and (C) outlet connector means for connecting the other of the ball-shaped end portions to a fluid discharge means, said outlet connector means including (i) an annular, hollow, outlet outer member of resilient material and extending along a second axis and circumferentially surrounding said other ball-shaped end portion, said outlet member having an annular flange extending radially inwardly of the second axis to bound a second circular opening having a diameter smaller than the outer diameter of said other ball-shaped end portion, said outlet member resiliently engaging said other ball-shaped end portion, said flange having a second, concave, inner, circumferential surface, (ii) an annular, hollow, outlet locking ring mounted within the outlet member and having a second, concave, inner, circumferential wall which, together with the second, inner, circumferential surface of said flange, form a generally spherical second socket for rotatably receiving said other ball-shaped end portion to orient said second axis in a range of inclination angles relative to said longitudinal axis, said second, concave, inner, circumferential wall extending substantially to the end face on said other ball-shaped end portion to increase the range of the inclination angles, and (iii) an outlet seal mounted in sealing engagement among the outlet member, the outlet locking ring and said other ball-shaped end portion.
