"COMANDO A CASSETTO ROTANTE DI UN MOTORE A COMBUSTIONE INTERNA A DUE TEMPI" "ROTATING DRAWER CONTROL OF A TWO STROKE INTERNAL COMBUSTION ENGINE"
RIASSUNTO SUMMARY
L' invenzione ha per oggetto il comando a casset d? un motore a combustione interna a due tempi , il cui ass sviluppa parallelamente all' asse dell ' albero a gomiti e che viene azionato da una cinghia dentata. Nel caso dei comandi a cassetto rotante noti per il comando del sistema aspirante di questi motori i cassetti vengono azionati da una coppia di ruote icoidi oppure di ruote dentate coniche , che vengono integrate da un altro albero oppure da una serie di ruote dentate cilindriche, da catena o da cinghia dentata. Nel comando di un oassetto rotante , il cui asse ? perpendicolare al-: l' asse dell' albero a gomiti , per mezzo di una cinghia dentata, la cinghia dentata, azionata tramite due rulli , lavora in due piani perpendicolari l'uno all ' altro? Il diffetto del comando con ruote coniche oppure con ruote icoidi consiste nel fatto che detto comando ? complicato ed usando una cinghia dentata, che non corre in un piano , il comando non ? sicuro e presenta una breve durata. The invention relates to the command to casset d? a two-stroke internal combustion engine, whose ax develops parallel to the axis of the crankshaft and which is driven by a toothed belt. In the case of the known rotary drawer controls for controlling the suction system of these motors, the drawers are driven by a pair of Icoid wheels or bevel gear wheels, which are integrated by another shaft or by a series of cylindrical gear wheels, from chain or toothed belt. In the control of a rotating set-up, whose axis? perpendicular to: the axis of the crankshaft, by means of a toothed belt, the toothed belt, driven by two rollers, works in two planes perpendicular to each other? The defect of the command with bevel wheels or with Icoid wheels consists in the fact that said command? complicated and using a toothed belt, which does not run in a plane, the command is not? safe and has a short duration.
L? invenzione risolve questo problema grazie al fatto che la dentatura della cinghia dentata ? in presa da un lato con la dentatura della ruota del cassetto e dall 'altro lato con i denti della ruota condotta del comando ausiliario? L' asse del comando ausiliario ? parallelo all ' asse dell' albero a gomiti ? Il comando a cassetto proposto oonsente l' uso di un unico cassetto di diametro molto grande per parecchi cilindri. L? invention solves this problem thanks to the fact that the toothing of the toothed belt? in engagement on one side with the toothing of the drawer wheel and on the other side with the teeth of the driven wheel of the auxiliary control? The axis of the auxiliary control? parallel to the axis of the crankshaft? The drawer command proposed allows the use of a single drawer of very large diameter for several cylinders.
DESCRIZIONE DESCRIPTION
L' invenzione ha per oggetto il comando a cassetto rotante di un motore a combustione interna a due tempi , il cui asse non si sviluppa parallelamente all' asse dell ' albero a gomiti comandato da una cinghia dentata? The invention relates to the rotary slide control of a two-stroke internal combustion engine, whose axis does not develop parallel to the axis of the crankshaft driven by a toothed belt?
Sono noti dei motori a combustione interna a due tempi , i quali presentano una distribuzione del sistema aspirante con un casset t? rotante , il cui asse si sviluppa obliquamente all ' asse dell' albero a gomiti, per cui ? possibile una disposizione vantaggiosa del carburatore direttamente sul cilindro? Questi cassetti vengono comandati da una coppia di ruote icoidi oppure di ruote dentate coniche, che vengono integrate da un altro albero oppure da una serie di ruote dentate cilindriche , da una catena oppure anche da una cinghia dentata? E* nota anche una soluzione nella quale un cassetto viene comandato con un asse perpendico lare all ' asse dell ' albero a gomiti per mezzo di una cinghia dentata? Questo cassetto lavora con l' aiuto di due rulli disposti in due piani perpendicolari tra di loro? Two-stroke internal combustion engines are known which have a distribution of the suction system with a cassette. rotating, whose axis develops obliquely to the axis of the crankshaft, so? possible an advantageous arrangement of the carburetor directly on the cylinder? Are these drawers controlled by a pair of Icoid wheels or bevel gear wheels, which are integrated by another shaft or by a series of cylindrical gear wheels, by a chain or even by a toothed belt? Is a solution also known in which a drawer is driven with an axis perpendicular to the axis of the crankshaft by means of a toothed belt? Does this drawer work with the help of two rollers arranged in two planes perpendicular to each other?
Il difetto dei cassetti usati fino ad ora, aventi una trasmissione di ruote dentate coniche oppure di ruote icoidi, consiste nel fatto che la realizzazione ? complicata. Il sostanziale difetto di ogni cinghia che non corra in un piano, ? il suo scarso affi^ damento e la sua breve durata. The drawback of the drawers used up to now, having a transmission of bevel gear wheels or of icicidal wheels, consists in the fact that the realization? complicated. The substantial defect of any belt that does not run in a plane,? its poor confidence and its short duration.
Questi difetti vengono eliminati dal comando a cassetto rotante, il cui concetto consiste nel fatto che l'asse della ruota per cinghia condotta del comando ausiliario si sviluppa parallelamente all'asse dell'albero a gomiti, ? disposto su una ruota motrice di una cinghia dentata e nel fatto che i denti della ruota del cassetto avente lo stesso asse del cassetto rotante fra la ruota motrice e la ruota condotta sono in presa con la dentatura della cinghia dentata* Nel punto di ingranamento dei denti della ruota del cassetto con dentatura della cinghia dentata la superficie ed il fianco della cinghia dentata sono in contatto col rullo ausiliario. I denti della ruota del cassetto sono in presa con delle sporgenze laterali della dentatura della cinghia dentata. Con la soluzione proposta si ottiene il comando di un cassetto, il cui asse si sviluppa obliquamente rispetto all'asse dell'albero a gomiti. Normalmente l'asse del cassetto ? all'inoirca perpendicolare all'asse dell'albero a gomiti. Questo ? ottenuto per mezzo di una semplice cinghia dentata, sicura, che corre in un piano. Questa cinghia dentata aziona in modo usuale la ruota condotta del comando asuliario, ad esempio dell'accensione, dell'alternatore, della pompa dell'olio e della pompa dell'acqua, eventualmente senza un rullo ausiliario. La ru?ta dentata fissata sull?albero del cassetto ingrana nella cinghia dentata per mezzo di denti sagomati in modo opportuno, oppure pu? essere usata una cinghia avente una dentatura interna.e laterale. These defects are eliminated by the rotary spool drive, the concept of which is that the axis of the driven belt wheel of the auxiliary drive runs parallel to the axis of the crankshaft,? arranged on a driving wheel of a toothed belt and in the fact that the teeth of the drawer wheel having the same axis as the rotating drawer between the driving wheel and the driven wheel are in engagement with the toothing of the toothed belt * At the point of engagement of the teeth of the drawer wheel with toothed belt toothing the surface and side of the toothed belt are in contact with the auxiliary roller. The teeth of the drawer wheel are in engagement with the lateral protrusions of the toothed belt toothing. With the proposed solution, the control of a drawer is obtained, the axis of which develops obliquely with respect to the axis of the crankshaft. Normally the axis of the drawer? approximately perpendicular to the axis of the crankshaft. This ? obtained by means of a simple toothed belt, safe, which runs in a plane. This toothed belt usually drives the driven wheel of the asuliary drive, for example the ignition, the alternator, the oil pump and the water pump, possibly without an auxiliary roller. The toothed wheel fixed on the shaft of the drawer meshes with the toothed belt by means of suitably shaped teeth, or can it be inserted into the toothed belt. a belt having an internal and lateral toothing be used.
Il vantaggio del comando a cassetto rotante consiste nella semplicit? e nell'assoluto affidamento, che possono consentire un uso ampliato dei motori a due tempi di concezione molto vantaggiosa? Il comando a cassetto rotante proposto consente l'uso di un unico cassetto di diametro maggiore per parecchi cilindri? The advantage of the rotating drawer control consists in the simplicity? and in the absolute reliance, which can allow an extended use of the two-stroke engines of very advantageous conception? Does the proposed rotary drawer control allow the use of a single larger diameter drawer for several cylinders?
jUn esempio di realizzazione del oomando a cassetto rotante ? rappresentato nei disegni allegati. jAn example of the realization of the rotary drawer control? represented in the accompanying drawings.

Nel basamento 1 ? supportato girevole l'albero a gomiti 4, alla oui estremit? ? sistemata la ruota motrioe 5 ohe aziona la cinghia dentata 6? La cinghia dentata 6 aziona la ruota dentata 7 di un comando asuliario non rappresentato. L'asse 8 della ruota con-. dotta 7 ? parallelo all'asse ^ dell'albero a gomiti 4? L'alimentazione della miscela carburante dal carburatore 10 viene comandata dal cassetto rotante 11, il cui asse 12 non si sviluppa obliquamente rispetto all'asse 9 dell'albero a gomiti 4? Sull'albero 13 del cassetto rotante 11 ? fissata la ruota 14, la quale ingrana nella dentatura 15 della cinghia dentata 6. In figure 1 are a cylinder 2 and a head 3 mounted on the base 1? In the basement 1? supported swivel the crankshaft 4, at the end of which? ? arranged the drive wheel 5 which drives the toothed belt 6? The toothed belt 6 drives the toothed wheel 7 of an asuliary drive not shown. Axis 8 of the wheel con-. learned 7? parallel to the axis ^ of the crankshaft 4? The supply of the fuel mixture from the carburetor 10 is controlled by the rotating spool 11, whose axis 12 does not develop obliquely with respect to the axis 9 of the crankshaft 4? On the shaft 13 of the rotating drawer 11? fixed the wheel 14, which meshes with the toothing 15 of the toothed belt 6.
