An annular seal (61) is in intimate contact with interengaging male and female members (41, 51) which can pivot and oscillate relative to each other. At least one member (51) has an annular sealing surface (56,57) over which the seal(61)slides while remaining in sealing contact along its whole circumferential length throughout the oscillation range of the pivot joint. <IMAGE> |
