Abstract

The object of the invention of developing a rotary piston machine, which is to be embodied as a prime mover or as a work machine consisting of two piston mounts rotatably mounted on an axle and being capable of performing a relative movement, wherein they are connected to a straight-line thrust crank mechanism, which serves to generate a relative movement, which causes a conversion of a uniform movement into an non-uniform straight-line movement of the piston mount, was solved in that a center axle of each piston liner stands at right angles on a diameter of a piston mount and in that each piston mount comprising elliptical gearwheels, which are turned relative to one another by 90° and the gearwheels, as mating gears being turned relative thereto by 90°, are fixedly connected to an output, wherein they are rotatably mounted on the axle in the point of intersection of the smallest and of the greatest diameter, on the one hand, and are connected to the output shaft on the other hand, and the working pistons in the piston liners of the one piston mount are connected to the other piston mount via hinged levers and the working pistons in the piston liners of the other piston mount are connected to the first piston mount via hinged levers.

A rotary piston machine consisting of two piston mounts centrically mounted on an axle independent on one another so as to be rotatable and so as to be capable of performing a relative movement to one another, which are connected to a straight-line thrust crank mechanism, which serves to generate a relative movement of the piston mounts and causes a conversion of a uniform rotary movement into an non-uniform straight-line movement of the piston mount in each case, wherein they are connected to a drive/output shaft at the drive/output side to a double drive so as to be offset at an angle and each piston mount encompasses at least two piston liners, which are arranged so as to be offset by 180° on a defined orbit comprising a constant diameter with a working piston provided therein in each case, wherein the piston mounts are connected to one another via the working pistons, characterized in that a center axle (13) of each piston liner (3;

4) stands in each case at right angles on a diameter (15) of the respective piston mount (1;
2) and each piston mount (1;
2) is connected to gearwheels (17;
18), which are turned relative to one another by 90° and which encompass the shape of an ellipsis, wherein the gearwheels (17;
18) are connected to the respective piston mounts (1;
2) turned relative to one another by 90° and the gearwheels (19;
20), which are used as mating gears being turned relative to one another by 90° are fixedly connected to an output shaft (21) and are thus components of a oval gear mechanism, wherein the elliptical gearwheels (17;
18;
19;
20) are rotatably mounted on the axle (14) in the point of intersection of the smallest diameter and of the greatest diameter, on the one hand, and on the output shaft (21) on the other hand, and the working pistons (11), which are arranged in the piston liners (3) of the one piston mount (1) are connected to the other piston mount (2) via hinged levers (12) and the working pistons (11), which are arranged in the piston liners (4) of the other piston mount (2) are connected to the first piston mount (1) via hinged levers (12).
