DESCRIZIONE DEL TROVATO DESCRIPTION OF THE FOUND

Il trovato proposto a domanda di brevetto per Invenzione Industriale, consiste in un sistema per il gonfiaggio dei pnewnatici dei veicoli mediante l'utilizzo di una bomboletta spray contenente una innovativa, per tale uso, miscela di gas allo stato liquido. The invention proposed in patent application for an Industrial Invention consists of a system for inflating the tires of vehicles by using a spray can containing an innovative mixture of gases in a liquid state for this use.

L'ideazione consente il vantaggio di poter gonfiare un pneumatico di un veicolo in un tempo molto ridotto: in media 30 secondi. Tempo estremamente significativo, se confrontato con il metodo di gonfiaggio con i normali compressori per auto a 12 volt, che consentono il gonfiaggio del pnewnatico in tempi compresi tra i 4 ed i 20 minuti. The concept offers the advantage of being able to inflate a vehicle tire in a very short time: on average 30 seconds. Extremely significant time, if compared with the inflation method with normal 12 volt car compressors, which allow the tire to be inflated in times between 4 and 20 minutes.

La miscela di gas trovata, sconosciuta nell'impiego del gonfiaggio di pnewnatici dei veicoli, è una miscela composta da: Tetrafluoroetano in una percentuale variabile tra il 70 ed il 99 %; e da pentafluoroetano in una percentuale variabile tra il 30 e l'1%, con peso specifico di 1,2Kgllitro. The gas mixture found, unknown in the use of vehicle tire inflation, is a mixture composed of: Tetrafluoroethane in a variable percentage between 70 and 99%; and from pentafluoroethane in a variable percentage between 30 and 1%, with a specific weight of 1.2Kgllitro.

La miscela di gas trovata non contiene Azoto, gas nocivo per l'ambiente, quindi possiamo definirla ecologica e, più sicura in termini di utilizzo rispetto alle bombolette spray contenenti aria compressa. The gas mixture found does not contain nitrogen, a gas that is harmful to the environment, so we can define it as ecological and safer in terms of use than spray cans containing compressed air.

La maggiore sicurezza nell'uso di bombolette riempite con la miscela trovata è riscontrabile anche nei confronti dello stoccaggio del prodotto. The greater safety in the use of cans filled with the found mixture can also be found in the storage of the product.

La miscela di gas trovata è preferita ma non esclusiva, in quanto è possibile usare altri tipi di gas tecnici che abbiano simili caratteristiche e miscelati in varie percentuali. Che sostanzialmente possono garantire uguali risultati. The gas mixture found is preferred but not exclusive, as it is possible to use other types of technical gases having similar characteristics and mixed in various percentages. Which can basically guarantee the same results.

Tale vantaggio si traduce in una maggiore sicurezza per quanti, in situazione di emergenza, si trovano a gonfiare un pneumatico della vettura in strade dove non esiste od è ridotta, la corsia di emergenza. This advantage translates into greater safety for those who, in an emergency situation, find themselves inflating a car tire on roads where the emergency lane does not exist or is limited.

Inoltre la miscela di gas non è infiammabile, quindi conferisce una maggiore sicurezza di utilizzo rispetto ai sistemi di gonfiaggio con bombolette spray ( aerosol) che utilizzano miscele di gas infiammabili. Furthermore, the gas mixture is non-flammable, therefore it provides greater safety of use than inflation systems with spray cans (aerosols) that use flammable gas mixtures.

Oltre a risultare maggiormente vantaggiosa in termine di tempo di gonfiaggio del pneumatico. In addition to being more advantageous in terms of tire inflation time.

Nell'utilizzo pratico del trovato, occorre tener presente il rapporto tra: tipo di miscela di gas trovata; tipo di valvola di trasferimento dell'aerosol; e posizionamento della bomboletta durante l'utilizzo. In the practical use of the invention, it is necessary to keep in mind the relationship between: type of gas mixture found; type of aerosol transfer valve; and positioning of the can during use.

Ad esempio: utilizzando la valvola in dotazione ad una bomboletta spray del tipo illustrata nel DIS.l, riempita con una miscela del volume di 400 mI. al 90 % circa, di tetrafluoretano ed il lO % circa, di pentafluoroetano, allo stato liquido, con posizionamento della bomboletta in posizione verticale durante l'immissione della miscela all'interno del pneumatico; possiamo gonfiare un pneumatico di un veicolo del peso di 2,5 tonnellate in circa 30 secondi. For example: using the valve supplied with a spray can of the type illustrated in DIS.l, filled with a mixture of the volume of 400 ml. about 90%, of tetrafluoroethane and about 10%, of pentafluoroethane, in the liquid state, with positioning of the can in a vertical position during the introduction of the mixture into the tire; we can inflate a vehicle tire weighing 2.5 tons in about 30 seconds.

Per modelli di pneumatici diversi, in dotazione ad altri tipi di vetture, occorre usare per il gonfiaggio bombolette contenenti un diverso volume della miscela trovata, adeguata al diverso volume del pneumatico; sempre per rispettare i 30 secondi standard prefissati per il gonfiaggio del pneumatico alla giusta pressione. For different tire models, fitted to other types of cars, it is necessary to use cans for inflation containing a different volume of the mixture found, suitable for the different volume of the tire; always to respect the standard 30 seconds for inflation of the tire at the right pressure.

Il sistema trovato, in funzione della miscela dei gas tecnici usati, deve tener conto delle possibili variazioni derivanti dal tipo di valvola di trasferimento dell' aerosol usata, per determinare la relativa posizione della bomboletta durante l'utilizzo. The system found, depending on the mixture of technical gases used, must take into account the possible variations deriving from the type of aerosol transfer valve used, to determine the relative position of the can during use.

La posizione della bomboletta, in funzione del tipo di valvola di trasferimento dell'aerosol usata,ed in funzione del tipo di miscela di gas tecnici adottata; per ottimizzare il gonfiaggio del pneumatico può risultare: verticale; oppure orizzontale, oppure indifferentemente orizzontale o verticale. The position of the can, according to the type of aerosol transfer valve used, and according to the type of technical gas mixture adopted; to optimize tire inflation it can be: vertical; or horizontal, or indifferently horizontal or vertical.
