Abstract
There is disclosed an internal combustion engine. The internal combustion engine includes a cylinder unit and a piston unit. The cylinder unit is rotatably coupled to a pair of spaced-apart crankshafts, with the cylinder unit moveable along a longitudinal axis. The piston unit is continually disposed within the cylinder unit, with the piston unit rotatively coupled to a second pair of spaced-apart crankshafts. The piston is moveable along the longitudinal axis in a direction opposite the direction of the cylinder during a combustion cycle. Both the cylinder unit and the piston unit are structured to be balanced relative to the respective center-of-gravity of each unit. Each center-of-gravity is located midway between the pair of spaced-apart crankshafts to which each unit is rotatively coupled.
Claims21
An internal combustion engine comprising:
- a movable cylinder unit including a hollow cylinder rotatably coupled to a pair of spaced-apart crank shafts with each crankshaft defining a bore receiving a cylinder locating pin coupled to the cylinder unit, the cylinder locating pins aligned on the same horizontal plane off-set from one another, with the cylinder unit movable along a longitudinal axis, the cylinder unit further comprising a sleeve valve, including a cap liner and a beveled pinion gear keyed to one of the crankshafts and in operative engagement with a ring gear coupled to the sleeve valve and rotatively coupled to the cylinder, wherein one cylinder locating pin is coupled to the hollow cylinder and another cylinder locating pin coupled to the cap liner of the sleeve valve;
- and a moveable piston unit continually disposed within the movable cylinder unit, with the movable piston unit rotatably coupled to a second pair of spaced-apart crank shafts with each crankshaft defining a bore receiving a piston locating pin coupled to the movable piston unit, the piston locating pin aligned on the same horizontal plane off-set from one another, the piston movable along the longitudinal axis in a direction opposite the direction of the cylinder, both the movable cylinder unit and movable piston unit are configured to be balanced relative to the respective center-of-gravity of each unit, with each center-of-gravity located midway between the pair of spaced-apart crank shafts to which each unit is rotatably coupled.

- further comprising a pair of oval ports defined in the cylinder wait, with the oval ports in line with one another and 45° apart, the oval ports configured to selectively align with a single oval port defined in the sleeve valve;
- and wherein the single oval port defined in the sleeve valve and the pair of oval ports defined in the cylinder wall are the same width and each of the three ovals are aligned at the same longitudinal position along the longitudinal axis of the cylinder.
