ABSTRACT:
The present invention relates to a bidirectionally reciprocating piston engine comprising (a) a cylinder block having a cylinder and a crankcase formed at the base of the cylinder, (b) a bidirectional type piston body having a piston accommodated in each of the cylinders of the cylinder blocks disposed opposite to each other with the axial line of the piston body coincident with that of the cylinders, an arm at the base of the piston, and a long hole-like crank drive part which is formed at the central part of the arm, (c) a rotating slider slidably disposed in the crank drive part; and (d) a crankshaft having a crank pin to which the rotating slider is rotatably attached, wherein since two pistons are coaxially disposed at one crank pin, the vibration is suppressed, the running noise is remarkably low and the load onto the crankshaft may be remarkably lowered, and in which the productivity thereof is excellent with a limited number of parts and the mass production thereof can be carried out at a low production cost.
