Abstract
A barrel engine includes a central drive shaft and a cam plate interconnected to the drive shaft. The barrel engine includes a plurality of cylinders each having a longitudinal axis that is generally parallel with the drive shaft. The axes of the cylinders are arranged in a generally circular manner about the drive shaft. A pair of guide rods are provided, which correspond to each cylinder of the engine. Each guide rod has an axis generally parallel with the axes of the cylinders. The barrel engine includes a plurality of piston assemblies. Each piston assembly includes a piston head slidably coupled to one of the cylinders for reciprocal movement along the axis of the cylinder. Each piston assembly also includes a guide block slidably coupled to a respective pair of guide rods for guiding the piston head during reciprocal movement along the axis of the cylinder.
