ABSTRACT:
A hydrostatic coupling with a housing fastened on a first coupling shaft. Several gears which operate as geared pumps are contained in recesses of the housing and are arranged in a planetary manner about a gear fastened on a second coupling shaft as a sun gear. The sun gear fastened on the second coupling shaft forms a geared pump with each of the planetary gears driven by the sun gear. The sun gear as well as the planetary gears on the one hand engage against the smooth inner housing wall, and on the other hand engage against a sealing plate which is axially externally adjustable against spring force. This sealing plate, according to axial adjustment, entirely or partially closes the circulation passages of the geared pumps.
