<p>A fluid transfer device 1 for a central tyre inflation system comprises a fluid connector 3 for conveying fluid, such as compressed air, and a support 6, preferably an annular collar, mounting fluid connector 3. Fluid connector 3 has a spherical surface portion 11 preferably cooperating with a spherical surface portion 9 of support 6, and is arranged to pivot relative to support 6 around two axes, each preferably orthogonal to a longitudinal axis defined by support 6; the angle may be limited by a nozzle 35 and shoulder 39. Fluid transfer device 1 is mounted to a hollow shaft (51, Figure 4) comprising a conduit (52, Figure 4) communicating with fluid connector 3; an articulated joint, for example a constant velocity joint (50, Figure 4), may connect the shaft to a further hollow shaft (53, Figure 4); each hollow shaft may suitably be a drive shaft or wheel stub axle.</p> |
