PCT No. PCT/EP87/00401 Sec. 371 Date Jan. 10, 1989 Sec. 102(e) Date Jan. 10, 1989 PCT Filed Jul. 22, 1987 PCT Pub. No. WO88/00641 PCT Pub. Date Jan. 28, 1988.A rotating piston machine has a casing 2 with a shaft 5 borne in the casing 2. In an annular space 1 there are arranged rotating elements which bear in sealing manner against the walls of the annular space 1. Each rotating element (3, 4) has four outwardly extending sector-shaped vanes (3a-3d, 4a-4d). The two rotating elements (3, 4) are arranged coaxially; their vanes (3a-3d, 4a-4d) engage in one another, so that in each case one vane of the one rotating element is arranged between two vanes of the other rotating element. By a cam track control it is achieved that, on rotation of the shaft 5, both rotating elements execute rotations with cyclic changes in the speed of rotation and the distances between the vanes (3a-3d, 4a-4d). The cam track control has in this case for each rotating element eight rolling elements which interact with an inner and an outer curved track non-positively and free from play.
