Abstract

The invention relates to a selfpowered hydraulic motor, manufactured in any conventional technical method, which being provided with a merely initial starting-off impulse provided by any known means, henceforth operates automatically and provides a continous of energy without being supplied with power from any external source, by means of an originally selfproduced force exerted through system 20, where system 20 performs a counterbalancing of the pressure exerted by pistons 5 and 7 connected to the crankshaft 4 of the said hydraulic motor.

Description

THE FIELD OF THE INVENTION

The present invention relates to the field of the art of hydraulic motors and engines in general.

THE BACKGROUND ART

The motors, particularly the broadly used internal combustion engines with conventional fuel of the prior art have caused heavy environmental pollution, whereas such conventional fuel resources might soon be exhausted.
The object of the invention is therefore to provide a hydraulic motor, which will produce work without being supplied with power from other external source.
The selfpowered hydraulic motor of the invention is offered to replace internal combustion engines, wherever the latter might be used.

BRIEF DESCRIPTION OF THE DRAWINGS

Fig.2 shows a front sectional view of another preferred embodiment of the invented hydraulic motor.

ANALYTICAL DESCRIPTION OF THE INVENTION

Reffering now the the accompanying drawings, the invented hydraulic motor comprises two similar units A and B. In order for the motor to operate, the tank 11 is filled with a suitable liquid, which is transferred through the pipes 17 and nozzles 1 into chambers 2 and 3. Then crankshaft 4 is rotated by any desired conventional method.
During such movement of crankshaft 4, piston 5 moves towards the centre of the cylinder 6, whereas the pistons 7 and 8 move outwards within cylinders 13 and 14 respectively.
Piston 5 is of a slightly larger diameter than pistons 7 and 8 and performs a stroke twice as long within cylinder 6 as the stroke performed by pistons 7 and 8 within cylinders 13 and 14.
Since, during such movement, the volume of the liquid introduced through piston 5 into chamber 2 is larger than the volume of liquid discharged through chamber 2 via pistons 7 and 8, the pressure created within chamber 2 closes the valve 15, whereas the valve 9 opens and liquid under pressure is introduced into chamber 3 and following that it is passed to the tank 11 via pipe 10, wherefrom it is again pumped.
Pipe 10 comprises a regulating valve 12, suitable for regulating pressure within chamber 3 at the desired level.
During such movement of crankshaft 4 within unit A, piston 5 moves outwards within cylinder 6, whereas pistons 7 and 8 move inwards the cylinders 13 and 14, thereby creating a vacuum within chamber 2, whereby valve 9 closes, valve 15 opens and the liquid pumped is introduced through nozzle 1.
As the rotation of crankshaft 4 continues and following the creation of the necessary pressure within chamber 3, the pressure thereby created within chamber 3 alternatively pushes pistons 8 towards the centre whilst valves 9 remain closed and vacuum is present within chamber 2.
The alternately pushed pistons 8 with their connecting rods 18 rotate the crankshaft 4 with a torque, the value of which corresponds to the pressure within chamber 3, since crankshaft 4 feels a minimal opposing force by that unit whose valves 9 are open. This happens because by means of the system depicted with numeral 20, the pressure exerted by pistons 5 and 7 onto the crankshaft 4 is counterbalanced.
The counterbalancing of pressure exerted by pistons 5 and 7 onto the crankshaft 4 depends upon firstly the difference in the diameters of piston 5 and pistons 7 and 8 and secondly on the difference in the spacing of points 19 and 21 from the centre of the crankshaft 4.
The above description being directly applicable to Fig.1 is also valid for the embodiment depicted in Fig.2, except that in Fig.2 the crankshaft 4 is mounted outside chamber 2.
The selfpowered hydraulic motor manufactured in any conventional method, when provided with a merely initial starting in any conventional way, it operates automatically and produces energy, which is self-produced in an original way through system 20 without making use of energy from any external source (fuel, etc.)
The invented hydraulic motor may be manufactured to operate with a serial arrangement of two pairs (Fig.1 or 2), those crankshafts will be joined, where the pairs will be mutually assisted in the operation of the motor.
In this latter embodiment, the cranks are placed in 90 intervals onto the crankshaft, so that when the cranks of one pair reach the upper and bottom dead-centre respectively (Figs 1 and 2), the cranks of the other pair will lie in a horizontal position. In this way, throughout the operation of the motor, pressure is continously exerted by one of the pistons 8 and periodically by both pistons 8 onto the crankshaft.

Claims

1. Selfpowered hydraulic motor manufactured in any conventional technical method, which being provided with a merely initial starting-off impulse provided by any known means, henceforth operates automatically and provides a continuous supply of energy without being supplied with power from any external source, by means of an originally selfproduced force exerted through system 20, where system 20 performs a counterbalancing of the pressure exerted by pistons 5 and 7 connected to the crankshaft 4 of the said hydraulic motor, where the said hydraulic motor comprises two units A and B with chambers 2 and 3, being filled with suitable liquid through a tank 11, where in one cycle of rotation of said crankshaft 4, said piston 5 moves outwards within cylinder 6 and pistons 7 and 8 move inwards cylinders 13 and 14, whereby formation of vacuum within chamber 2 results to the opening and closing of valves 9 and 15 and the continuous rotation of said crankshaft 4.
