Abstract: 793,787. Pipe joints. BRISTOL AIRCRAFT, Ltd. Nov. 21, 1955 [Nov. 19, 1954], No. 33626/54. Class 99(1). [Also in Group XXXIII] In an aerofoil structure comprising two portions hinged for relative movement, conduit means for conveying fluid under pressure from one portion to the other comprises a first duct in one portion extending parallel to the hinge axis, a second duct in the other portion appreciably spaced from the hinge axis, a connection member surrounding and universally jointed to each duct in a fluid-tight manner, a telescopic duct connecting the two connection members and allowing movement thereof towards or away from one another, and means operable by the pressure of the fluid for producing a force on the connection member to the first duct, to pressure balance it. Fig. 1 shows a wing having a flap 2 at its trailing edge working on an axis 3. A boundary layer energizing slot 4 extends spanwise and is fed through ducts 7 and 8 from a duct 9, Fig. 2. A part spherical enlargement 11 of the duct 9 has an aperture 111 and mounts a connection member 12. A supply duct 16 in the wing has a part spherical portion 18 which mounts a connection member 19. The telescopic duct is formed by an inner sleeve 24 fast with member 19, and an outer sleeve 25 fast with member 12. An annular piston 26 is secured to the end of sleeve 25, and is in sealed sliding engagement with sleeve 24 and a cylinder 27 fast to member 19. An annular ring 28 fast to cylinder 27 is in sealed sliding engagement with sleeve 25. Ports 33 and 34 are formed in sleeves 25 and 24 respectively, whereby fluid under pressure is conveyed through these ports and the clearance space between the sleeves to a space 32. The space 35 behind piston 26 is vented to atmosphere by ports 36. By making the annular area of piston 26 equal to the crosssection of the duct, the total force on member 12 is reduced to zero. The sealing ring 21 of member 19, which takes the reaction force against the expansive force of the liquid under pressure, may be of graphite. The space 37 is vented at 136. The duct 16 may be replaced by a duct parallel to the hinge axis and jointed to member 19 exactly as duct 9 is to member 12, in which case the two parallel ducts may be about equally spaced from the hinge axis.
