Abstract
The invention relates to a device for sealing the transitional region between a rotatably mounted spraying arm of a dishwashing machine and its stationary bearing member by means of a sealing element, which is disposed therebetween and is impinged by the rinsing water flowing therethrough. The sealing and sliding friction functions are separated through the inclusion of a slip ring in the transitional region and this achieves significant sealing with a long service life.
