ABSTRACT:
A hydrostatic bearing mounts a rotatable control part of a planetary rotation machine according to the orbital principle. Pockets are arranged at least in one sliding surface. Each pocket is surrounded by a bearing gap and fed with bearing fluid by a supply line under pressure. The bearing gap is small, so that there is only a small flow of bearing fluid from the pocket. The supply line, the feed with bearing fluid and the bearing gap are designed so that the pressure required for a rigid bearing can be built up in the pocket. Using the working fluid at half the high pressure in the bearing pocket results in a bearing which has minimal leakage and frictional losses and can be realized at low cost, so that the efficiency of the planetary rotation machine as a whole is increased.
