An internal combustion engine for producing mechanical drive power by combustion of a fuel. The internal combustion engine includes two or three rotary pistons which are rotationally fixedly connected to an output shaft and rotatably arranged in a respective annular cylinder, and at least one passage between the annular cylinders and a respective movable shut-off slide valve for periodically closing the cylinders adjacent to the passage.

An apparatus including a first piston member rotatable about a first rotational axis and a rotor with a first chamber and pivotable about a second rotational axis. The first piston member extends across the first chamber. The rotor and first piston member are rotatable around the first rotational axis, and the rotor is pivotable about the second rotational axis to permit a relative pivoting motion between the rotor and the first piston member linked to the rotor rotating about the first rotational axis.

An anti-locking mechanism of a spherical compressor rotor, an anti-locking power mechanism of a spherical compressor, and a spherical compressor. A pin boss is fixedly arranged on a turntable shaft, and guide pins are movably connected with a guide sleeve. A concave slideway is arranged in a cylinder block spherical surface or a cylinder lower spherical surface, and is distributed along a sliding track of the guide sleeve on the corresponding cylinder block spherical surface or cylinder lower spherical surface in a rotation process of a turntable. A main shaft rotates and drives the turntable. When the turntable rotates to a position at which a turntable axis and a piston axis are superposed, the turntable can continue to rotate around the turntable axis by means of torque obtained by the guide pin from the concave slideway, and thus a problem of a dead point of movement of a spherical compressor rotor is solved. Because the concave slideway is arranged outside a spherical working cylinder of a spherical compressor, the sealing effect is good.

An apparatus comprising a first piston member (22) rotatable about a first rotational axis (30) and a rotor (16) comprising a first chamber (34a) and pivotable about a second rotational axis (32). The first piston member (22) extends across the first chamber (34a). The rotor (16) and first piston member (22) are rotatable around the first rotational axis (30), and the rotor (16) is pivotable about the second rotational axis (32) to permit a relative pivoting motion between the rotor (16) and the first piston member (22) linked to the rotor (16) rotating about the first rotational axis (30).

The invention relates to a rotary piston engine (2) which operates as a pump, condenser or motor for a liquid or gaseous medium. The rotary piston engine (2) has a first gear (4) having a first central axis (I), a second gear (6) arranged opposite the first gear (4) and having a second central axis (II), and a drive shaft (8) having a third central axis (III) and a sliding plane (10, 12) fixedly connected to the drive shaft (8). The first central axis (I) and the second central axis (II) enclose an angle (3) which is not equal to 180. The third central axis (III) and at least one central axis (I, II) from the group comprising the first central axis (I) and second central axis (II) enclose an angle (1, 2) which is not equal to 0 or 90. The sliding plane (10, 12) and the central axis (I, II) are perpendicular to each other. The first gear (4) has a first end face (14) having a first has toothing (16) that h at least one first tooth (18), and the second gear (6) has a second end face (20) having a second toothing (22) that has at least one second tooth (24), wherein a first number of first teeth and a second number of second teeth differ from each other. The first tooth (18) and the second tooth (24) engage with each other in such a way that a working chamber (26) is formed by means of a meshing of the teeth (18, 24). A volume formed by means of the at least one working chamber (26) is changed by the meshing of the teeth (18, 24). The at least one working chamber (26) is delimited by a conically shaped inner wall (30) of a housing (28). The at least one working chamber (26) can be connected to a supply flow (40) and an outlet flow (42) for the medium. According to the invention, a component (4, 6) from the group comprising the first gear (4) and second gear (6) is coupled to the housing (28) such that a rotation of the drive shaft (8) causes only the components (4, 6) to tumble. The respective other components (4, 6) from the group comprising the first gear (4) and second gear (6) is coupled to the sliding plane (10, 12) such that the respective other component (4, 6) rotates and tumbles by means of a rotation of the drive shaft (8).
