Abstract

The invention has for object the generation of mechanical energy for both civil and industrial use. This result is obtained by using both the force of gravity and buoyancy which act on a pair of hollow prisms immersed in a liquid contained in a tank. In fact, the pair of hollow prisms when it is immersed completely in the liquid undergoes the buoyancy and rises generating mechanical energy that transmits by means of appropriate mechanisms and when the liquid disappears below the lower bases of the hollow prisms they descend by gravity still generating mechanical energy. At the end of descent the pair of hollow prisms compresses the liquid which is located below their lower bases and which rises internally along a vertical hollow up to the top base of the hollow prisms where it accumulates to then be poured around the hollow prisms themselves. At this point the buoyancy again generates and causes them to raise and so on. A small motor powered by conventional energy will drive the service mechanisms and overcome the frictions.

Description

HYDRAULIC MOTOR

TECHNICAL FIELD:

The invention has for its object the generation of mechanical energy both for civil and industrial use. First object of invention is to generate mechanical energy in a easy and economic way and without any withdrawn energy from non-renewable energy source, except the conventional one required for the movement of the auxiliary mechanisms and to overcome f iction, but using the force of gravity of a body and the buoyancy of a liquid on it.

BACkGROUND ART:

Usually the mechanical energy is produced by machines, better specified as engines, which are distinguished according to the type of energy that they transform and then are the most diverse. There are inertia motors, pneumatic motors, hydraulic motors, nuclear motors, wind engines, volumetric engines, heat engines, engines that use natural energy of ocean waves, biomass engines, electric motors and spring motors.

In particular the hydraulic motors give the kinetic and pressure energy of a liquid stream to a moving machine member, for example a driving shaft, which can be coupled to different types of users. One example are the hydraulic turbines that stoke power plants etc.

There are two main categories of hydraulic engines:

a) the hydrodinamic hydraulic motor that uses mainly the kinetic energy of a liquid stream; b) hydrostatic hydraulic motor that uses mainly the pressure

possessed by the liquid stream.

There are patented hydraulic motors not easy to built which exploit or a continous flow of water or pressure differences. To name a few: US 999 579 A - DE 199 13 008 A 1 - JP 54 134239 A- ES 479 95 Al -DE 168 219 C - JP 63 131871 A- JP 63 192966 A.

DISCLOSURE OF INVENTION:

This invention seeks to take advantage of not only the

hydrostatic pressure of a liquid that acts on two hollow prisms placed in a tank but also the weight force acting on them and without the need for any liquid moving in the tank for pick up kinetic energy nor exploit differences in pressure.

The mecanical energy is drawn from the motor shaft belonging to a system of levers and step-up wheels kept in motion by the hydraulic motor which is characterized in that a primary tank with rectangular plant is divided by two longitudinal fixed walls , parallel to long sides of the primary tank, in three tanks and the central of these is larger than two external side which are equal and two hollow prisms are inserted in it by telescopic way, joined togheter but to form between them a vertical hollow, that alternately sway in height by means additional weights and that by means of levers and step-up wheels system, driven by a motor with conventional engine power, are locked when they reach the position of maximum and of mini- mum height and that each top base of these hollow prisms form a top tank by two longitudinal walls, each composed of a fixed wall with overlapped a mobile wall, and two short walls and moreover a system of levers and step-up system, also it driven by the same motor with conventional engine power, turns to a certain angle the two mobile walls both outside and inside and the foot of vertical rod is located in the middle point of the distance between the centers of gravity of the two top bases of the hollow prisms, connected by a section, and the top of vertical rod is connected to oscillating rocking lever around the pin, located on the top of one of two long walls of the primary tank, which transmits the vertical reciprocating motion of the hollow prisms to the driving shaft of the levers and step- up wheels system from which it draws mechanical energy.

In an advantageous manner the lower bases of the hollow prisms must be raking of an opportune angle to the horizontal.

In an advantageous manner the vertical hollow, of opportune height, has the transversal vertical section lightly truncated cone.

In an advantageous manner the top bases of the hollow

prisms form a top tank by means of two longitudinal walls, each composed of a fixed wall with overlapped a mobile wall, and two short walls.

In an advantageous manner four uprights are guides

to the two hollow prisms during their downward and ascent mo- tion.

In advantageous manner the diagonals of top bases of hollow prisms have stiffering ribs.

In advantageous manner a load valve for liquid,

necessary to start the hydraulic motor or to mantain constant the liquid level, is placed in an opportune and high point in each of two long walls of the primay tank.

In advantageous manner an outlet valve for liquid, necessary to stop alternative motion of the hollow prisms, is located in an opportune and low point in each of two long walls of the primary tank and in a little higher point than longitudinal fixed walls.

In advantageous manner additional weights are opportunely located in addition to weight of all mobile part and are calculated considering the specific gravity of the used materials to built the mobile part and the resistance value of the user which is always opposed to alternative motion of the hollow prisms.

In advantageous manner shock absorbers are opportunely placed on the bottom of the central tank to cushion the descent of the hollow prisms .

One possible working of the hydraulic motor is the following. The two hollow prisms, which are those that produce the variations of the liquid level, are inserted telescopically, with additional weigths placed in any point that is deemed

desirable, in the central tank full of liquid. The two hollow prisms sink because of their weight and additional weights also winning the resistance of any user (all suitably calculated) and meanwhile the liquid rises along the vertical hollow so as to fill the two top tanks. At this point all the mobile part floats because the total weight of the mobile part with the weight of the liquid in the top tank was calculated to be equal to the buoyancy which the entire mobile system receives from below and from vertical hollow (static balance) being also no resistance of a probably user, and it is locked in this position by a locking and unlocking system placed in the side tanks moved by a motor to conventional supply.

When the top tank is full, by a levers and step-up wheeles system moved also by the same motor, the two mobile walls open in such a way the liquid circumscribed by them leak in the side tanks up to fill them up to the base of the top tank (or as required). So the hollow prisms are unlocked by the same locking and unlocking system.

Consequently the hollow prisms, not being longer in equilibrium, with the side surfaces and that of the bottom free and surrounded by the liquid, receive the buoyancy upwards and acquire a certain momentum. The raising of the hollow prisms does not lower the liquid level in the two side tanks because when the hollow prisms rise the side surfaces that protrude from the water are offset to the same extent from those side surfaces which were formerly enclosed in the fixed walls of the central tank. Besides the cavity that gradually is formed below the lower bases of the hollow prisms is filled with the liquid which, descending by gravity, was located both between the fixed walls of the top tank and in the vertical hollow lightly truncated cone.

Thus the volume of the submerged parts remains constant and thus also the push given by the lower bases of the two hollow prisms. But the push ends before the lower bases of the two hollow prisms reach the upper limit of the two longitudinal fixed walls and this due to exhaustion of the liquid which descends by gravity. However the two hollow prisms continue to move vertically under the received pulse effect.

Meanwhile, the oscillating rocking lever around the pin transmits mechanical energy to the driving shaft of the levers and step-up wheels system.

When the lower base of the two hollow prisms exceeds the fi- xed walls a long opening similar to the lenght of the central tank opens and allows to the liquid that is in the side tanks to overflow inside the central tank beginning to fill it. In this way the liquid level on the side surfaces decreases and simultaneously the hollow prisms with the additional weights continue to rise vertically but decreasing their momentum due to the force of gravity and the user's resistance. At equilibrium with their weight force the hollow prisms and the additional weights have reached the maximum excursion in height while the eventual user resistance is zero and in this position they stop and are blocked by the locking and unlocking system and meantime the fluid which was located in the side tanks, on account of the crack that has developed between the fixed walls and the lower bases of the hollow prisms, all poured out in the central tank and, adding to the liquid that was left in the vertical hollow and between the fixed walls of the top tank (which fell by gravity), has reached the height of the fixed walls. From what is known , as already seen previously, that the liquid that fills the central tank up to the brim necessarily must have a volume at least equal to the sum of the liquid contained in the ver- tical hollow with the volume of the liquid contained in the top tank.

Simultaneously the hollow prisms with the additional weights, having no liquid around them and suspended in the air, are unlocked by the locking and unlocking system and descend by gravity, overcoming the resistance of a possible user, until their lower bases meet the liquid trapped in the central tank between the fixed walls and compress it by pushing it in the top tank through the vertical hollow. As the hollow prisms descend by gravity, the displaced liquid, that expands on their top bases, contributes with their weight to the descent. The hollow prisms and additional weights, finished the descent and compressed all the liquid of the central tank and carried it in the top tank, always are blocked with the same locking and unlocking system and simultaneously the two mobile walls of the top tank open and the liquid contained in it comes out in the side tanks up to fill them up to the base of the top tank (or as desired). So the cycle is repeated continuosly swinging the rocking lever and providing mechanical energy.

When mechanical energy is not required, the rocking lever oscillations occur with no resistance by the user, which is always opposed to the direction of oscillation, and therefore the hollow prisms perform the maximum and the minimum excursion in heigh with a speed and a greater range of when the hydraulic motor works against the user's resistance.

BEST MODE FOR CARRYING OUT THE INVENTION:

In general, except in cases of special use, the value of additional weights corresponds to the resistance value that the hydraulic motor can oppose to the user. Therefore, for generate high powers the hydraulic motor can also be advantageously built with high specific weight material.

This invention is realized without having to assemble numerous components and also with the use of materials of low cost. The choice of these materials is based both on their structural strenght and on their compatibility with the used fluid.

INDUSTRIAL APPLICABILITY:

This hydraulic motor employs mechanical groups of weight and reduced dimensions and which is useful in the event that it should build for high power motors. It is also reliable both for the continuity of service and for the ease of adjustment and maintenance.

This invention thus conceived is susceptible to numerous modifications and variations, all falling within the inventive concept, and furthermore all the details are replaceable with other technically equivalent.
