Abstract
According to the invention a seal is established between a rotary spray arm and a stationary pedestal support for the spray arm. Liquid from a pump, which forcibly delivers liquid to the spray arm is forced between cooperating parts of the spray arm and spray arm support in such a manner that a sealing split ring is urged both axially and radially relative to the rotational axis of the spray arm into sealing engagement with surfaces on both the spray arm and spray arm support.
