Abstract

Motore endotermico avente di una pluralità di cilindri, ciascuno dei quali è definito da un rispettivo vano avente simmetria assiale ricavato all'interno di un basamento, e ciascuno dei quali definisce, insieme ad un pistone alloggiato assialmente scorrevole nel cilindro stesso e ad una testata collegata con il basamento, una camera di combustione servita da un sistema di alimentazione portato dalla testata; i cilindri essendo suddivisi in una prima ed in una seconda bancata, ciascuna delle quali è formato da coppie di rispettivi primi e secondi cilindri disposti secondo uno schema a V a convergere verso un rispettivo albero motore per ciascuna bancata, e le due bancate essendo accoppiate rovesciate e tra loro affacciate in modo che i primi ed i secondi cilindri di ciascuna coppia di cilindri della prima bancata sono disposti congiunti dalla parte della rispettiva testata a formare un V con rispettivamente i primi e secondi cilindri di ciascuna corrispondente coppia di cilindri della secondo bancata, in modo che ciascuna coppia di primi cilindri delle due bancate definisce una prima camera di combustione, e ciascuna coppia di secondi cilindri delle, due bancate definisce una seconda camera di combustione, in comune ai rispettivi pistoni.
