“MOTORE IDROSTATICO CON ROTORE A PARA-TIE MOBILI AZIONATO DA LIQUIDI COMPRESSI†. â € œHYDROSTATIC ENGINE WITH MOVABLE PARA-TIE ROTOR ACTIVATED BY COMPRESSED LIQUIDSâ €.

RIASSUNTO SUMMARY

In questo motore idrostatico sì convertono le forze di compressione applicate costantemente a diversi campi liquidi a volumi assegnati in energia meccanica, cinetica di rotazione. In this hydrostatic engine they convert the compressive forces applied constantly to different liquid fields at assigned volumes into mechanical energy, kinetic of rotation.

Dentro il motore in un rotore sono ricavate alcune camere piene di liquido chiuse superiormente da paratie mobili che hanno lo stesso profilo esterno del rotore. Inside the motor in a rotor there are some chambers filled with liquid closed at the top by movable bulkheads that have the same external profile as the rotor.

Le camere sono disposte con i loro baricentri fuori dall'asse di rotazione del rotore e hanno superimi che, in funzione della pressione del lìquido e della loro posizione generano, nel rotore una coppia di forze che squilibra il rotore e nelle paratie mobili una coppia di forze equilibrate rispetto al loro centro dì pressione idraulica esterno. The chambers are arranged with their centers of gravity outside the rotation axis of the rotor and have surfaces which, depending on the pressure of the liquid and their position, generate a couple of forces in the rotor that unbalance the rotor and in the movable bulkheads a pair of balanced forces with respect to their external hydraulic pressure center.

DESCRIZIONE TECNICA TECHNICAL DESCRIPTION

In sintesi si tratta di un motore ideato per convertire le spinte idrostatiche di un campo liquido a volume assegnato in regime di pressione uniforme in energia meccanica, cinetica di rotazione, il campo di applicazione di questa nuova classe di motori à ̈ estendibile fino a dove à ̈ utile energia meccanica, cinetica di rotazione, per il raggiungimento di uno scopo attraverso una macchina alimentata da un motore. In summary, it is an engine designed to convert the hydrostatic thrusts of a liquid field with assigned volume in a uniform pressure regime into mechanical energy, kinetic of rotation, the field of application of this new class of motors can be extended up to where à It is useful mechanical energy, kinetic of rotation, for the achievement of a purpose through a machine powered by an engine.

Le caratteristiche principali di questo motore idrostatico risiedono nella costanza dimensionale dei volumi interni, invariabili durante il funzionamento, e nel particolare disegno di alcune delle parti soggette ai carichi idrostatici del campo liquido con il quale non tutte le sono in contatto al fine di creare delle aree di spinta che consentono di generare i momenti che danno origine alle condizioni di squilibrio dell’insieme delle parti rotanti sul loro asse di rotazione. The main characteristics of this hydrostatic motor reside in the dimensional constancy of the internal volumes, invariable during operation, and in the particular design of some of the parts subject to the hydrostatic loads of the liquid field with which not all of them are in contact in order to create areas thrust which allow to generate the moments that give rise to the unbalance conditions of the whole of the rotating parts on their rotation axis.

Per quanto riguarda eventuali precedenti storici, allo stato attuale della tecnica, non si ha notizia dell’esistenza di precursori con caratteristiche tecniche tali da essere presi in considerazione per eventuali confronti di similitudini. As regards any historical precedents, at the present state of the art, there is no news of the existence of precursors with technical characteristics such as to be taken into consideration for any comparisons of similarities.

Per comprendere al meglio la descrizione tecnica del motore in oggetto in tema d’esposizione sono allegate tre tavole di disegni dove, a solo titolo illustrativo e per nulla limitativo, sono rappresentate: To better understand the technical description of the motor in question in terms of display, three tables of drawings are attached where, for illustrative purposes only and not at all limiting, they are represented:

-la fig, 1, che mostra in vista nello spazio il rotore completo con una paratia mobile fuori dalla sua sede, - fig, 1, which shows in space view the complete rotor with a movable bulkhead outside its seat,

<->la fig, 2, che mostra il rotore isolato in una vista nello spazio. FIG. 2, showing the isolated rotor in a spatial view.

- la fig, 3, che mostra il rotore con le paratie mobili in una trasparenza frontale. - fig, 3, which shows the rotor with the movable bulkheads in a frontal transparency.

- le figg. 4 e 5, che mostrano l’albero motore in due assonometrie dimetriche di superficie e in trasparenza, - figs. 4 and 5, which show the crankshaft in two dimensional axonometries on the surface and in transparency,

- la fig, 6, che mostra il motore idrostatico completo in assonometria dimetrica. - fig, 6, which shows the complete hydrostatic motor in dimetric axonometry.

Con riferimento a fig. 1 il rotore 1 ha delle sedi 2 nelle quali sono ricavati i vani 3 e 4, in questo caso a forma di diedro, nei quali viene contenuto un preciso volume di liquido che ha come pareti superiori le facce piane inferiori delle paratie mobili 5 inserite nelle sedi 2. With reference to fig. 1 the rotor 1 has seats 2 in which the compartments 3 and 4 are obtained, in this case in the shape of a dihedral, in which a precise volume of liquid is contained which has as its upper walls the lower flat faces of the movable bulkheads 5 inserted in the locations 2.

Sui piani e nelle pareti in reciproco accoppiamento fanno tenuta le guarnizioni 6. The gaskets 6 are sealed on the surfaces and in the walls in mutual coupling.

Come da fig. 2 e 3 i vani 3 e 4 sono raggiunti dai un condotti 7 proveniente dalla sede che ospita l’albero motore. As shown in fig. 2 and 3 compartments 3 and 4 are reached by a duct 7 coming from the seat that houses the crankshaft.

L’albero motore 8, come dalle figg. 4 e 5, à ̈ dotato dei fori 9 e 10; all’estremità del foro 10 ha sede il pistoncino 11 spinto dall’elettromagnete 12. In questo caso la linguetta 13 ha i fori 14 affinché il liquido contenuto nei vani 3 e 4 possa essere raggiunto dalle compressioni esercitate dal pistoncino 11 nel liquido. The drive shaft 8, as shown in figs. 4 and 5, is equipped with holes 9 and 10; the piston 11 pushed by the electromagnet 12 is located at the end of the hole 10. In this case the tab 13 has the holes 14 so that the liquid contained in the compartments 3 and 4 can be reached by the compressions exerted by the piston 11 in the liquid .

Considerando il tutto chiuso all'interno del motore di fig, 6, nel quale il rotore à ̈ totalmente immerso in un liquido, preferibilmente olio per trasmissioni oleodinamiche, si evince che generando una pressione nelle camere del rotore lo olio tende ad espellere le paratie mobili dalle loro sedi. Questo porta ad un innalzamento della pressione dell’olio circostante al rotore che impedisce la fuoriuscita delle paratie, mentre all’interno del rotore nelle superfici dei vani opposte a quelle delie paratie mobili si hanno due spinte dirette in senso opposto le cui risultanti passano lontano dall'asse di rotazione e generano un momento nel rotore. Considering everything closed inside the motor of fig. 6, in which the rotor is totally immersed in a liquid, preferably oil for hydraulic transmissions, it is clear that by generating a pressure in the rotor chambers the oil tends to expel the movable bulkheads from their locations. This leads to an increase in the pressure of the oil surrounding the rotor which prevents the escape of the bulkheads, while inside the rotor in the surfaces of the compartments opposite to those of the movable bulkheads there are two thrusts directed in the opposite direction, the results of which pass away from the axis of rotation and generate a moment in the rotor.

Per quanto riguarda l’equilibratura delle paratie mobili, in fase di progetto à ̈ necessario bilanciare le pressioni interne alle camere relativamente alla posizione dei centri di spinta idrostatica delle facce dei vani proiettate sulle pareti superiori, appartenenti alle paratie mobìli, in modo tale che il momento delle paratie sul loro baricentro idrostatico esterno sia zero. As regards the balancing of the movable bulkheads, during the design phase it is necessary to balance the pressures inside the chambers relative to the position of the buoyancy centers of the faces of the compartments projected on the upper walls, belonging to the movable bulkheads, so such that the moment of the bulkheads on their external hydrostatic center of gravity is zero.

In definitiva, le paratie mobili hanno il loro fulcro nel liquido che permea esternamente il rotore, ricevono dall’interno due spinte che le mantiene in equilibrio sul fulcro, spinte che contemporaneamente generano il momento squilibrante del rotore sul suo asse. Ultimately, the movable bulkheads have their fulcrum in the liquid that permeates the rotor externally, they receive two thrusts from the inside that keep them balanced on the fulcrum, thrusts that simultaneously generate the unbalanced moment of the rotor on its axis.
