ABSTRACT:
An explosion engine comprises: a rotary shaft with axis A; four cylinders 6, 7, 8, 9 in a star aligned in pairs on two axes B and C perpendicular to the axis A and to each other, but not coplanar; a first assembly of two pistons 10, 11 suitable to slide within two of the said cylinders and connected together head to tail by a first rigid cross piece 12; a second assembly of two pistons 13, 14 suitable to slide in the other two cylinders and connected together head to tail by a second rigid cross piece 15; and a mechanism with eccentrics suitable to transform the alternating slidings of these two assemblies into rotations of the shaft or conversely. On the one hand, each cross piece 12, 15 is guided for smooth sliding in two sleeves 24 solid with the casing 1 of the machine and therefore with the cylinders 6, 7, 8, 9, and on the other hand, each piston 10, 11, 13, 14 is fixed on one extremity of the corresponding cross piece by a device permitting relative transverse, but not longitudinal, displacements or wobbling of said piston relative to the said cross piece.
