    (54) Internal combustion motor


    (57) This invention refers to a motor, indistinc­tly combustion or diesel one, having in each chamber an operative unitary group in front of a conventional only cylynder, incorporates two parallel cylinders identical between them, permanently related through a gases com­municating pass in such a way that the inlet valve is fixed on the other, whilst the spark plug or the injec­tor are situated in above cited pass. The two pistons acting inside these cylinders are associated to the res­pective crankshaft and dully related between themselves to obtain an absolutely synchronized movement.
    Tis structuralization facilitates the place­ment of the valves and allows the dimensional increase of same obtaining at the same time a major balance in forces transmissions to outlet shaft and a substancial reduction in the motor's vibrations.
