Lift motor

Abstract

The invention relates to an 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.
