Abstract:
A rotary piston machine for a pump, a compressor, a turbine or a motor, the machine comprising:a casing having an inner spherical volume, and having at least one inlet and one outlet opening; a power component having a first shaft supported in said casing and with one of a first drive and a first output device, said power component having a first spherical surface truncated by an first end face and a first base surface, said first spherical surface having a center lying in a first axis of rotation of said first shaft, said first spherical surface having a first diameter corresponding to an inner volume of said casing, wherein said first base surface is perpendicular to said first axis of rotation and said first end face is formed by the motion of a generating line, curved in a plane extending through said first axis and connected to a first point on said first axis, along a cycloid generating curve with at least 2 cycloids, wherein a circle generating said cycloids, rolls along a circular line of intersection between a plane parallel to said first base surface and said first spherical surface with a point on said circle forming said cycloids moving on said first spherical surface; a blocking component connected to a second shaft supported in said casing, said blocking component having a second spherical surface truncated by a second end face and a second base surface, a center of said second spherical layer lying on a second axis of rotation of said second shaft, said second spherical surface having a diameter corresponding to said inner volume of said casing, said second base surface extending perpendicularly to said second axis, said second end face defining teeth cooperating in mating engagement with said power component, wherein the number of blocking component teeth differs from the number of power component cycloids by one, wherein said power component and said blocking component move synchronously about said first and said second axes, said first and said second shafts being disposed at a working angle with respect to one another, wherein working chambers are formed between said cycloids and said teeth which, with each rotation, pass through a defined maximum and minimum determined by said cycloids, a shape of said teeth and said working angle.
