PCT No. PCT/DK94/00454 Sec. 371 Date Aug. 12, 1996 Sec. 102(e) Date Aug. 12, 1996 PCT Filed Dec. 5, 1994 PCT Pub. No. WO95/16129 PCT Pub. Date Jun. 15, 1995A hydraulic piston engine driven by a lubricant-free, water-based pressure fluid, and comprising an enclosing housing and a piston-connected drive shaft supported by radial journal bearings in bearing bushings. One of the sliding surfaces of the radial journal bearing comprises a recess with a bearing-supporting hydrostatic pressure fluid pocket. The center of the recess is displaced by an angle ( alpha ) in the direction against the direction of rotation of the drive shaft, seen in relation to the geometrical, radial mean point in the high-load area for transmission of the piston forces to the bearing surface via the drive shaft. Hereby a particularly reliable piston motor of the type indicated is provided. |
