1. Apparatus for generating a torque, having at least two bodies (12) which are coupled to one another in such a way that they can perform a rotational movement, in which one body (12) moves in the direction of the force of gravity and the other in the direction opposite thereto, each body (12), when changing the direction of movement, altering its volume so that the volume of the body or bodies (12) moving in the direction of the force of gravity is less than that of the bodies (12) moving in the opposite direction. 2. Apparatus according to claim 1, characterized in that the two bodies (12) coupled to one another are so designed that, despite the alternating changes of volume of the individual bodies (12), the total volume of all bodies (12) is substantially constant. 3. Apparatus according to claim 1 or 2, characterized in that the bodies (12) are arranged opposite one another in pairs relative to the rotational movement. 4. Apparatus according to one of claims 1, 2 or 3, characterized in that the bodies (12) become immersed in a liquid during at least part of their rotational movement. 5. Apparatus according to one of the preceding claims, characterized in that the individual bodies (12) are connected to one another by a tension member (11) which runs in an annular manner over at least one deflection device (10). 6. Apparatus according to claim 5, characterized in that the deflection apparatus (10) possesses at least one deflection wheel (13) which is mounted on a shaft (14) from which the torque can be taken off. 7. Apparatus according to one of the preceding claims, characterized in that each set of two bodies (12) assigned to one another as a pair, preferably all bodies (12), have the same dimensions. 8. Apparatus according to one of the preceding claims, characterized in that each body is designed as a piston-and-cylinder unit (12), the piston (21) being movable into its extended or retracted position by the weight acting on it as a function of the orientation of the piston-and-cylinder unit (12) relative to the force of gravity. 9. Apparatus according to claim 8, characterized in that the piston length (Ik) satisfies the following equation: where h is the maximum depth of immersion of the body (12) into the liquid, pf is the density of the liquid and pk is the density of the piston material. 10. Apparatus according to claim 8 or 9, characterized in that each piston-and-cylinder unit (12), in the event of a change in direction of movement, is automatically transferred from its one position, in which the piston (21) is extended or retracted, into its other position, in which the piston (21) is, respectively, retracted or extended. 11. Apparatus according to claim 8 or 10, characterized in that the cylinder chambers (16) of the individual piston-and-cylinder units (12) are connected to one another in order to permit a fluid exchange. 12. Apparatus according to claim 11, characterized in that the cylinder chambers (16) are connected to one another in an annular manner, preferably via a hose. |
