1. A power-generation device comprising:

  • an output shaft, having a central axis;

    four cylinders, disposed symmetrically and regularly about the central axis of the output shaft and axially-movable with respect to the output shaft, each having a central axis parallel to the central axis of the output shaft, an internal volume, an internal cylinder surface, a central axis, a first end and a second end;

    four cylinder heads, each having an internal cylinder head surface, an intake port, and an exhaust port, each such cylinder head being disposed at, and secured to, the first end of a cylinder;

    four pistons, each having an axis of motion aligned to the central axis of a cylinder, disposed in the internal volume of the cylinder and having a crown disposed toward the internal surface of the cylinder head secured to that cylinder, the crown of the piston, an internal cylinder surface, and the internal surface of the cylinder head for that cylinder together forming a combustion chamber for that cylinder;

    a swash plate, fixed to the output shaft, having a substantially-planar swash plate surface having a normal axis disposed at an angle of approximately 45 degrees to the central axis of the output shaft;

    four connecting rods, each having a principal axis, a first end axially and rotationally fixed to a piston, and a second end; and

    four followers, each secured to the second end of a connecting rod, respectively, and each having a substantially planar follower surface fixed to the connecting rod and having a normal axis disposed at an angle of approximately 45 degrees to the central axis of the output shaft.
