Definitions
- the invention relates to an apparatus for generating a torque.
- the object of the invention is to provide a further apparatus of the type named initially which, in particular, uses buoyancy forces to generate a torque.
- At least two bodies are coupled to one another in such a way that they can perform a rotational movement, in which one body moves in the direction of the force of gravity and the other in the direction opposite thereto, each body, when changing the direction of movement, altering its volume so that the volume of the body or bodies moving in the direction of the force of gravity is less than that of the bodies moving in the opposite direction.
- the apparatus according to the invention can also, in principle, be operated with an uneven number of bodies, provision is preferably made for the bodies to be arranged opposite one another in pairs relative to the rotational movement. A particularly uniform generation of torque is ensured by this symmetrical arrangement of the bodies in pairs.
- the apparatus according to the invention can be operated in any fluid which, with practicable changes in the volumes of the bodies, supplies a sufficiently large increase in buoyancy for at least the frictional forces acting in the apparatus to be overcome.
- the bodies Preferably, however, provision is made for the bodies to be immersed in a liquid during at least part of their rotational movement.
- a relatively large increase in buoyancy can be achieved even with a relatively small change in volume. For example, an increase in the volume of individual bodies by in each case 1 dm 3 (1 l) supplies an increase in buoyancy of 9.81 N (1 kp).
- the individual bodies are connected to one another by a tension member which runs in an annular manner over at least one deflection device, the deflection device having at least one deflection wheel which is mounted on a shaft from which the torque can be taken off.
- each set of two bodies assigned to one another as a pair, preferably ail bodies, is made for each set of two bodies assigned to one another as a pair, preferably ail bodies, to have the same dimensions. In this manner, the apparatus can be kept completely in equilibrium with regard to the weights acting on it.
- each body is designed as a piston-and-cylinder unit, the piston 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 relative to the force of gravity.
- the piston length l k satisfies the following equation: l k ⁇ h ⁇ p f p k
- each piston-and-cylinder unit in the event of a change in direction of movement, is automatically transferred from its one position, in which the piston is extended or retracted, into its other position, in which the piston is, respectively, retracted or extended.
- the cylinder chambers of the individual piston-and-cylinder units are connected to one another in order to permit a fluid exchange, the cylinder chambers being connected to one another in an annular manner, preferably via a hose.
- a self-contained fluid system can be formed in the cylinder chambers connected to one another, the effect of which is that the pressure created by the retraction of a piston changing to downward movement can be output via the self-contained fluid system to the piston of the piston-and-cylinder unit which is changing over to upward movement, which piston is moving out into its extended position, so that an additional pressure on the piston assists its movement into the extended position in order to increase the volume and compensate for any frictional losses arising.
- the fluid used in the cylinder chambers may be simply air or another gas; it is also possible, however, for example, to use a very light oil or a similar liquid as a fluid, which has the advantage that the pressure can be transferred particularly well.
- FIG. 1 shows a greatly simplified diagrammatic representation of an apparatus according to the invention having a pair of bodies to generate a buoyancy difference
- FIG. 2 a shows a simplified diagrammatic sectional representation of a piston-and-cylinder unit with the piston extended
- FIG. 2 b shows a simplified diagrammatic sectional representation of a piston-and-cylinder unit with the piston retracted
- FIG. 3 shows a simplified diagrammatic representation of an apparatus according to the invention with a plurality of bodies for generating a buoyancy difference, arranged in pairs.
- the apparatus according to the invention for the generation of a torque comprises a deflection device 10 for a tension member 11 to which two piston-and-cylinder units 12 are attached as a pair of bodies for generating a buoyancy difference.
- the deflection device 10 comprises a deflection wheel 13 , which is mounted on a shaft 14 , from which the torque generated by the apparatus according to the invention can be taken off.
- a generator for the generation of electrical energy may be connected to the shaft 14 .
- the tension element 11 can be designed as a chain, cable, toothed belt, tension belt or the like.
- each piston-and-cylinder unit 12 is held on the tension member 11 by means of fixing pins 15 or the like set at a distance apart in the longitudinal direction of the tension member 11 .
- a hose 17 or similar connection is provided as a fluid line and is fixed via corresponding connection pieces 18 and connectors 19 to the cylinders 20 of the piston-and-cylinder units 12 , so that the hose 17 is in fluid connection with the respective cylinder chambers 16 .
- a piston 21 is slidingly arranged in each cylinder 20 so that if the cylinder 20 is arranged as shown in FIG. 2 a, with its open side downwards, it slides downwards into its drawn-out or extended position as a result of the weight acting upon it.
- the cylinder 20 has, for example, an inward-directed flange 22 , while the piston 21 bears an outward-directed flange 23 interacting with the former.
- sealing means Arranged on the flange 22 are sealing means, not shown in detail, which seal off the cylinder chamber 16 in a gastight manner without substantially impeding the displacement movement of the piston 21 , in order to ensure that the medium surrounding the piston-and-cylinder unit 12 cannot penetrate into the cylinder chamber 16 .
- the apparatus according to the invention is completely arranged in water and that the cylinder chambers 16 , which are connected to one another via the hose 17 and form a self-contained fluid system, are filled with air.
- another medium may also be used, having a low viscosity and the highest possible density.
- the lightest possible oil may be used instead of air as the fluid filling the cylinder chamber 16 .
- An essential factor for the selection of the flowable media provided in the apparatus according to the invention is that the density of the medium provided in the cylinder chambers 16 should be less, preferably very much less, than that of the medium surrounding the piston-and-cylinder units 12 .
- the volume difference ⁇ V corresponds, in the case of a cylindrical piston 21 , to the product of the piston stroke l h and the cross-sectional area of the piston A k .
- the resultant force F R is the resultant force
- the piston length l k is preferably selected so that it satisfies the following equation: l k ⁇ h ⁇ p f p k
- h is the maximum possible depth of immersion of the piston-and-cylinder unit 12 , and hence of the piston 21 , in other words the distance between the lowest position of the free surface area 21 ′ of the piston 21 and the water surface
- P k is the density of the piston material.
- FIG. 3 shows an example of embodiment of the invention having 14 piston-and-cylinder units 12 in each case arranged in pairs with one another.
- this apparatus has a lower deflection device 13 with a deflection wheel 33 which is arranged on a lower shaft 34 .
- a resultant force F R acting on the tension member 11 is, disregarding frictional losses and the like, 6 ⁇ g ⁇ p f ⁇ V.
- This force F R causes the piston-and-cylinder units 12 to make a rotational movement, in which the piston 21 of each piston-and-cylinder unit 12 .
- each set of two piston-and-cylinder units 12 are assigned to each other as pairs, so that they are arranged opposite each other relative to the rotational movement, such as the top and bottom piston-and-cylinder units 12 . 1 a and 12 . 1 b or the piston-and-cylinder units 12 . 2 a and 12 . 2 b, the pushing-in of a piston 21 takes place on each occasion, in other words on the change from the position of the piston-and-cylinder unit 12 . 2 a to that of the piston-and-cylinder unit 12 . 2 a, while on the corresponding change from the position of the piston-and-cylinder unit 12 . 1 b to that of the piston-and-cylinder unit 12 . 2 b, the piston is moved out.
