Labyrinth seal for AC generator slip ring set

To protect the slip ring 13/brush 17 interface, a labyrinth seal excludes water from the space between shield 152 and slip-ring carrier122. The labyrinth comprises a radially outward annular stepped structure 31,34 of the shield 152 and a stepped structure 32 projecting toward the shield 152 along with an annular groove 33 both formed at the end portion of a slip ring support 122. Said end portion acts as a slinger, water entering the gap via route X3 being direct via X4 and migrating along the inner surface of the shield step to either be expelled or returned to the said surface by the slinger. The internal surface of the shield may include barriers 35 and a raised area 282 to divert to annular aperture 26 water entering the space when generator is not in use. Fig 7 shows a addition groove 37. A vacuum pump 22 is also driven.
