ABSTRACT:
A cylinder wheel member having a plurality of cylinder cavities is in meshing engagement with a piston wheel member having a plurality of piston elements between which segment-like cavities are provided. The meshing engagement of said wheel members provides expanding and contracting working chambers in the cylinder cavities of said cylinder wheel member as well as in the segment-like cavities of said piston wheel member. A disc-like commutator valve rigidly connected to said piston wheel member has two types of through passages, the first type of which connects the working chambers in said cylinder cavities of the cylinder wheel member to fluid inlet and outlet means of a casing rotatably supporting said wheel members and the second type of which connects the working chambers both in said cylinder cavities of the cylinder wheel member and in the segment-like cavities of said piston wheel member to said inlet and outlet means for a fluid. Thus, on both sides of the piston elements projecting into the cylinder cavities impulses are generated to drive one of said wheel members connected to a driving shaft.
