Abstract
The hydrostatic support arrangement comprises a piston-and-cylinder unit and the piston thereof is provided with a bearing shoe. The hydrostatic support arrangement is provided with a separate supply of pressure oil into the chamber of the cylinder of the piston-and-cylinder unit and to a further chamber arranged between the piston and the bearing shoe. The pressure oil passes from this further chamber through throttle bores to stabilizing pockets of the bearing shoe. A bearing pump for the supply of the pressure oil to the further chamber of the bearing shoe comprises a volumetric pump having a high delivery capacity for the delivery of large quantities of oil, while a pressure pump for the supply of the pressure oil to the cylinder of the piston-and-cylinder unit comprises a pressure-regulated pump having a smaller delivery capacity for delivering smaller quantities of oil. The bearing pump and the pressure pump are operatively interconnected such that the bearing pump delivers pressure oil to both the pressure pump and the further chamber of the bearing shoe.
