Description

PATENT FOR INVENTION: HYDRAULIC MOTOR USING ARCULUS THRUSH

FABRY Alexandre.

The present invention relates to a method for continuously recovering the work done by the emergence of a floating body subjected to Archimedes' principle, according to the rules of buoyancy. Archimedes' law states:

5 Any body immersed in a liquid, experiences an upward thrust equal to the weight of the displaced liquid.

The invention concerns the principle and implementation mechanism as defined and stated in the explanatory text that follows; we will describe the process and its operation, using the simple figure of the drawings, which is a diagram whose sole purpose is to situate the parts of the device in relation to one another. The diagram is understandable when one refers to the explanatory text.

We see in this unique drawing:

Function: The immersion tank 1 is attached to a rotating mechanism to prevent it from floating. This mechanism comprises two flanged wheels, one upper 2 and the other lower 2', connected by an endless chain consisting of floats 3 to 3/21 articulated together. The floats in positions 3/12 to 3/21 are contracted so that they are immersed at their smallest volume during the rotation of the assembly, thus experiencing the weakest possible Archimedes' buoyant force opposing the movement. From 3 to 3/9, the floats are expanded under the internal pressure of a gas, at least equal to the immersion pressure at the lowest point.

The floats were designed to have two rigid faces, while the lateral faces were made up of articulated bellows, so as to allow their compression and expansion.

In normal operation, the expansion gas reaches the 3 to 3/2" floats through the 6" valves; this gas

is varnished from the (compression, between positions 3/10 and 3/12 of the floats; passing under the cam 7. This gas circulates through the system 5, which, being fixed, has sealed rotation cheeks with the rotating drums carrying the floats 6 and 6'. The floats 3 to 3/21 have the particularity of not being able to expand beyond the volume reached in position 3/29 in order to maintain constant the internal pressure between 3 and 3/12.

Under the influence of cam 9, which guides or assists the deformation of the float at position 3, the Archimedes' principle generates a torque on the wheel's axis 2. This torque increases during rotation towards position 3/2. The rotating assembly will quickly become unbalanced, moving in the direction of the arrow, which also represents the dominant Archimedes' principle. This thrust will be maximum and constant on the floats in positions 3/2 to 3/9; it will decrease at position 3/10, depending on the progressive emergence of the float. It will increase between positions 3 and 3/2 as the float expands.

As soon as the float reaches position 3/10, communication with the float in position 3 is established by the simultaneous opening of valves 6 and 6' via the communication system 5, until positions 3/2 and 3/12 are reached. This communication occurs simultaneously with the action of cam 7', whose mechanical force compresses the float between positions 3/10 and 3/12, expelling its gaseous contents towards 3/3 and 3/2. Any additional work is taken from the rotation of the chain to compress

to consider the pressure losses of the transfer

For the system to operate continuously and efficiently, it is important that the work required for the transfer of gas be less than that provided by the emergence of the floats 5 between 3 and 3/10.

It is observed that when 3/10 and 3 are connected, neither the volume nor the pressure undergoes any change, the expansion of the gas as the immersion pressure decreased was prevented by maintaining the constant m)lume of the 10 eurs between 3/2 and 3/9. It follows from this that it will be sufficient to supply the system, for it to function, with the equivalent of the pressure losses in 6 and 5 as well as the rolling of the assembly.

If, on the contrary, the volume and pressure had varied, the fact would have resulted in an expenditure of energy for recompression of the gas, which would have been useless and harmful.

Similarly, in the case of pneumatic gas transfer, it will suffice to increase the compressor inlet pressure by the equivalent of the same pressure losses of the transfer and rolling.

It therefore appears that the emergence of the expanded floats is the driving force of the rotating assembly. The action will be continuous, each float reaching position 3 generating a new Archimedes' thrust.

The innovation of the present invention lies notably in preventing the internal pressure of the floats from relaxing during emergence. While floats with free expansion would certainly produce more work during emergence, their expansion

by causing a release of the gas as the immersion pressure decreases, to such an extent that it would require the recompression of the gas, whereas it is precisely the fact of avoiding going through this fold that allows the system to function well.

There is no problem with valves 6 and 6' being open simultaneously, since the same pressure is maintained in all components and does not vary at any point during operation. Let us now examine the various constituent and incidental elements of the device:

Immersion reservoir: It can reduce the volume of the useful liquid held near the organs, the importance not being its volume but the immersion height; its shapes therefore matter little.

Immersion fluid: it can be water or any other product whose density, fluidity and other characteristics are compatible with its intended use. Its density determines the Archimedes' principle; it will retain this characteristic from its pure state, a mixture or dilution, or even from dense particles kept in suspension, notably by the stirring of the floats.

Floats: Simply inflatable, spongy, alveolar, or elastic, they take on any shape deemed useful provided they are expandable and contractable in sufficient proportions. Their constant maintenance at a volume equal to or close to that of the initial

6

The emergence rate will be crucial, as this is an important basis for the proper functioning of the system.

The chain, whether simple or multiple, can be formed by the articulation of the floats together or made of other elements, including support and guidance components. The entire rotating assembly cannot be floating, for obvious reasons. The energy produced will be recoverable at the wheel shafts, which implies a connection between the chain, the wheels, and the axes of rotation.

Guidance and support system: will be useful or even necessary to contain the thrusts, whether mutual or ArcM. mede.

The ballast of the floating surfaces or their own weight: this will act at the highest point as a compression force on the float, and at the lowest point as a force causing its expansion. The overall weight (15) can constitute the driving force, in whole or in part, along with the buoyant force.

Rotating elements: The system of flanged wheels taken as an example may be replaced by any other method capable of performing the same function. Linear displacement elements may be used, acting on wheels, crankshafts, etc., which will not change the principle of the invention, simply applied in a different manner.

Gas transfer: The drawing provides for a rotating system at the same speed as the carrier wheels, it can be replaced by any other 25 we will cite as a non-limiting example, pipes following the floats in their movement, whether they are individual or collective, the important thing being the punctual operation of the values and the tinning of the whole.

The two primary qualities will be airtightness and a cross-section sufficient to ensure rapid transfer with minimal charge loss.

Compressed gas anmexe:uae 'compressed gas reserve will be capable of maintaining constant gas pressure within the device, capable of compensating for leaks, serving for starting the whole, for power modulation and for any other need which arises useful or necessary.

Modulating the volume of the floats: this is a possible technique to obtain a modification of power or rotation speed, or even to stop the entire system. By lowering the pressure, one can obtain the partial diameter of the floats and a reduced Archimedes' thrust.

Modulation of the immersion depth: This can be achieved by varying the level of the immersion liquid or by using a lifting or lowering system for the rotating assembly. This process, which allows the power to be modulated, can also facilitate repairs or maintenance; such an ancillary process may offer many advantages and may prove indispensable.

20 Advantages: Besides the fact that Archimedes' principle is not used nowadays, and this is to our knowledge, one will first think of the operation of such an engine without fuel or auxiliary energy and also of its operation using a liquid that it does not consume. Operational everywhere, it is not subject to climatic hazards. A wide variety of power outputs are possible as a single unit or in a battery. It proves suitable for various applications.

It has multiple energy needs; it does not pollute the environment. It can simply use water and air, and finally, the process appears to be perfectly reliable.

In electricity production, it provides a significant additional production to hydroelectric dams whose water bodies it can utilize.

Its ease of installation and lack of pollution will solve energy transport problems, losses, costs, aesthetic nuisances, and other issues. It could make individual production or the establishment of small local units preferable to gigantic factories.

Disadvantages: One could criticize its weight and its bulkiness, which is not very compressible, and perhaps for certain uses, a certain lack of flexibility.

15 Fixed or onboard engine: When fitted to a ship, it can dive below the waterline directly into the carrier fluid and, if it has a variable immersion depth, adapt to the draft and modulate its power.

On a moving vehicle, its weight and volume will be to some extent a disadvantage, especially on small vehicles. However, one might consider equipping electric vehicles where it would ensure a constant charge of the batteries and thus extend their operating range, reducing power loss, as each stop would be useful for recharging the batteries.

Counter-thrusts: due to Archimedes' principle or the weight of the floats, they will be taken into account when drawing up the "construction" plans. Weight and volume will play their roles in relation to the axes of rotation, given their lifting arm, which will not necessarily be the same in immersion as in emersion, this being able to intervene in an improvement of the driving torque.

Shallow water bodies: as an alternative to the device illustrated in fig. 1, we can cite a system using the alternating linear displacement of two floats connected to the two ends of a water 10 baseulamt em son milieu, submerged or emerging. These two floats are directly connected by the gas transfer system 5. The emerged float returns the gas (containing the gas) to the submerged float in a contracted position. The movement will be transmitted to the delivery shaft by means of two central ratchet wheels that will act in the same direction upon the intervention of an even or odd set of gears. The process has the disadvantage of producing energy with dead time; this will be overcome in various ways, notably by using a spring capable of continuously restoring the forces. Alternatively, the number of counterweights can be multiplied in the manner of internal combustion engines.
