In a hydrostatic bearing there is provided in known manner pairs of balancing pockets between the coacting bearing surfaces. To counteract the bearing load the pockets of each pair is fed with pressure fluid through a new combined throttle valve which not only distributes the flow of pressure fluid but also its throttling or constricting effect between the pockets of the pair. The valve contains a freely movable roller element cooperating with two pairs of diametrically opposed ports in the valve housing, the ports of one pair individually communicating with each its pocket of the pair of pockets, the ports of the second pair communicating with a pressure source or pump and a low pressure outlet or sump, respectively.
