Alternative crankdisk bearing support for the waissi internal combustion engine

An improved internal combustion engine, comprising:

• a driveshaft and means mounting the driveshaft for rotation about an axis;
• at least one pair of aligned and opposed cylinders;
• at least one double-headed piston, having at least one rigid connection between the piston heads, reciprocating in said pair of cylinders;
• a circular crankdisk, for each said piston respectively, installed on said driveshaft, and allowing for a small lateral movement of said crankdisk on said driveshaft;
• the said crankdisk having an outer annular surface formed about a center that is laterally offset from the center of rotation of the said driveshaft, and attached to the said driveshaft;
• the said piston body having a first slot, a second slot perpendicular to the first slot, each of said slots being perpendicular to the axis of the driveshaft and the crankdisk, the first slot being perpendicular to the piston axis and allowing the rotating movement of the driveshaft, and the second slot allowing the rotating movement of the crankdisk;
• a flat I-profile bearing ring, mounted on the annular surface of the said crankdisk, which engages slidably under hydrodynamic conditions the annular surface of the said crankdisk, and rolls or slides against the inside walls of the said second slot linear bearing surface provided axially through the double-headed piston;
• wherein the improvement comprises of the piston head connecting members, or structures, attached to both side substructures of the linear bearing surfaces of the two piston heads, serving a dual function by, first, forming a rigid, integrated, double-headed piston assembly, and second, by serving, without grooves or flanges, as side support for the bearing ring;
• whereby the said bearing ring and said bearing ring-crankdisk assembly, allowing for a small lateral movement of the said crankdisk and the said bearing ring, fit in-between the said connecting members, which, without grooves or flanges, keep the bearing ring in its designed place when the crankdisk rotates;
• whereby the said crankdisk with the aid of the said bearing ring transmits the piston force of the double-headed piston to the driveshaft and causes the driveshaft to rotate about its axis.
