Abstract
An internal combustion, reciprocating piston, motor has a rotating cylinder block. A journal bearing supports a roller that is fastened to a piston connecting rod or fastened to the piston so the roller pushes against an inclined surface on a stationary guide track fastened to a motor housing in order to cause the cylinder block and pistons to rotate. A lubricant is fed from a passageway on the rotational axis of the drive shaft radially outward, through passageways that align, and though a skirt on the piston, in order to lubricate the journal bearing. The rotating piston chambers are sealed against a stationary cylinder head by annular rings at the end of each chamber, and by curved linear seals extending between adjacent annular rings.

A method of lubricating an internal combustion motor having reciprocating pistons in a rotating cylinder block, the pistons being connected to a roller that pushes against an inclined surface on a stationary guide track fastened to a motor housing in order to cause the cylinder block and pistons to rotate about a rotational axis, the drive track having a cylindrical bearing surface that encircles a drive shaft that rotates about the rotational axis, the piston having a curved bearing surface abutting the cylindrical bearing surface comprising:
- forming a lubricant passage along the rotational axis and forming outwardly extending fluid passages in the drive shaft which place the lubricant along the rotational axis in fluid communication with at least one location on the exterior of the drive shaft but inside the motor;
- placing the at least one location in fluid communication with a piston fluid passageway extending through the piston to an inner surface where the piston bearing surface abuts the cylindrical bearing surface.
An internal combustion motor rotating a motor drive shaft having a rotational axis, comprising:
- a rotating cylinder block within which a plurality of pistons reciprocate along an axis parallel to the rotational axis of the drive shaft, the rotating cylinder block being mechanically coupled to and rotating with the drive shaft;
- a non-rotating motor casing having opposing cylinder heads and enclosing the rotating cylinder block, the pistons reciprocating in chambers defined within the cylinder block and further defined by one of the non-rotating cylinder heads;
- a non-rotating drive track fastened to the housing and having an inclined surface thereon;
- a roller coupled to the piston by a connecting rod, the roller contacting the inclined surface on the drive track, the roller moving around the drive track as the drive shaft rotates;
- and
- a journal bearing within the roller.
An internal combustion motor having at least two double headed pistons reciprocating in cylinders located in a cylinder block that rotates about a rotational axis of a drive shaft to which the cylinder block is connected, the double headed pistons being connected by a connecting rod having a curved surface facing inward toward the rotational axis and abutting a cylindrical bearing surface of a stationary guide track fastened to a non-rotating housing within which the cylinder block rotates, the cylindrical bearing surface being in a plane that is coaxial with the rotational axis, the housing having opposing ends each enclosed by a cylinder head with opposing ends of the drive shaft being rotatably supported by the opposing cylinder heads, the piston heads supporting a axle which mounts a journal bearing inside a roller which pushes against a surface of the guide track to rotate the cylinder block and pistons about the rotational axis, the drive shaft having a fluid lubricating passage along its rotational axis, the fluid passage extending outward to at least one location at an exterior surface of the drive shaft, the piston having a fluid passage through the piston in fluid communication with the at least one location and one of the journal bearing and the curved surface of the connecting rod.
