Abstract: Kinematics of a rotary piston engine are guided by a sliding guidance mechanism mounted in a biangular piston. The mechanism is arranged relative to a fixed point of a housing having a runway formed with a single-arc trochoid. A sliding component moves within a groove in the piston. A housing-mounted pin is coupled to the sliding component and defines a rotating radius during motion relative to the piston. The piston has a minimal opening in a sidewall for the pin to couple to the sliding component allowing a maximal portion of the piston to be available for lateral fluid exchange during piston movement.

Abstract: A sealing system of rotary piston machines, the rotor excludes rotor discs which are arranged next to one another, and which are seated on the common rotor axle and are pressed apart from one another by acting spring and/or gas forces in the joints between the discs in such a way that the end sides of the discs which point towards the side walls of the housing bear sealingly against the latter and thus prevent the access of the medium to the axles. Assemblies comprising movable shaped lamellae which adapt to the changing joint widths and prevent an inner flow around the rotor are present in the part joints between the discs.

Abstract: The parting line or groove between the piston halves of the rotor of a rotary piston engine are sealed by means of fools which conform to the configuration of a peripheral portion of the rotor and cover the parting line or joint.

Abstract: The invention relates to the control of the vanes of vane machines by means of a disk-shaped control link arranged inside a divided rotor, which control link is connected to the housing of the machine by means of a central axle in alignment with the rotor shaft and takes on the guidance of the vanes when the rotor rotates relative to the housing track.
