ABSTRACT:
A radial piston machine wherein fluid flows through the cylinders which are provided in a rotor, the disclosure provides a radial bearing in the middle between a plurality of at least two radial cylinder groups. Thereby the former bearings which were provided on the ends of the rotor can be reduced to smaller sizes to carry a lower radial load. The provision of the bearing in the middle of the rotor prevents the former miniturization of the control bodies on the ends of the rotor. The control bodies can now be radially enlarged and the restriction of the flow through quantities of fluid through the control bodies is overcome. The devices are now able to operate with a better efficiency and power. In order to obtain these features the medial radial bearing in the middle between the cylinder group must be of the specific structures of this patent application.
