Piston driven axial cylinder engine

Piston driven axial cylinder engine comprising,

• a cylinder block wherein the cylinders with their axes parallel and equidistant are arranged on a flange in a circular arrangement, having in the centre the motor main shaft, with its axis parallel to those of the cylinders,
• the flange being attached to stand off bolts, which flange and bolts make up part of a support body also comprising the support of the abovesaid motor main shaft, as well as the support carrier of the central pivot located in a way that the centre of this central pivot be on a continuation of the motor main shaft axis and spaced a certain distance from the cylinder block,
• the said central pivot on which, and in a way that their centres coincide, a disc is pivoted, which disc has in its centre and perpendicularly an integral bar, whose free extremity is pivoted in the excentric pivot of the motor main shaft,
• the said disc, being deprived of the freedom to rotate around the motor main shaft, has connecting rods pivoted in its periphery, whose pivoting centres correspond to the cylinders axes and are located equidistantly between each other as well as from the disc centre, and lye in one plane, which plane passes also through the disc pivoting centre,
• the connecting rods, being rigid and endowed with pivots in both ends, are pivoted in the other extremity to pistons, which are engaged in a sliding way to the cylinders,
• the said cylinders being shut in one end by the heads endowed with valves, the said valves being actuated by the lobes of the distribution disc,
• said distribution disc, that being located on the motor main shaft, takes its motion directly by it, or by the auxiliary drive disc,
• the said auxiliary drive shaft which taking its rotating motion by the motor main shaft of the first cylinder block, transmits it to the motor main shaft of the second cylinder block in case of a two cylinder blocks engine.
