Support in hydrostatic bearings

In a hydrostatic bearing for rotatably supporting therein a member comprising a shoe having an arcuate first surface confronting the member and having formed therein a pocket for a fluid under pressure, the first surface and said member being of a predetermined relative configuration to provide essentially a line contact between said member and the surface of said shoe at diametrically opposed locations in said arcuate first surface, the improvement comprising means defining a projection in said pocket having a second surface confronting the member of generally the same contour as said first surface to provide an additional essentially line contact between said member and said second surface generally aligned with the line contact between said member and said arcuate first surface and disposed approximately midway therebetween.
