ABSTRACT:
A double-acting piston engine has a crankshaft rotatable about a first central axis and having a crankpin having a second central axis which is spaced a distance from the first central axis, a cylinder assembly having a pair of cylinder chambers confronting each other along an axial line perpendicular to the first central axis, with the crankpin being disposed substantially between the cylinder chambers, and a piston assembly slidably disposed in the cylinder chambers and coupled to the crankpin. The piston assembly comprises a pair of pistons slidably fitted in the cylinder chambers, respectively, a joint disposed in the cylinder chambers and having opposite ends coupled to the pistons, respectively, the joint having a cylindrical opening defined therein, and a rotor rotatably fitted in the cylindrical opening for rotation about a third central axis, the rotor having an eccentric hole defined therein and spaced from the third central axis by a distance which is the same as the distance by which the second central axis is spaced from the first central axis, the crankpin being fitted in the eccentric hole thereby connecting the piston assembly to the crankpin.
