    The invention relates to a rotating piston bearing arrangement comprising an eccentric bearing member (1) and bearings (7, 8) connected thereto. In rotary piston machines with known bearings, the operating pressure, the variation of the load force due to the transmission and the eccentricity of the piston and bearing member acting on the rotating piston cause changes in the position of the rotary piston and deviations in the rotation of the central axis of the rotary piston and the piston. According to the invention, the bearing member (1) and the bearings (7, 8) form a support / bearing element (F) to which the central shaft (6) connected to the rotary piston (2) is connected eccentrically and with axial and rotational movement of the rotary piston (2) and central shaft the combination is supported and the resistance is reduced by applying the bearing pressure transmitted through the central shaft (6) via the bearing (8) and the bearing member (1) to the concave side of the support bearing (7) and the extreme along the wall surfaces formed in the piston movement space (9).
