Piston engine as a combustion engine or as a compressor with opposed cylinders

摘要

A piston engine in which opposedly working pistons are rigidly connected to each other by a hollow carrier through which the engine shaft extends. The carrier has interior wall portions with a series of staggered projections thereon. The shaft has a stack of toothed discs fixedly mounted thereon. The series of staggered projections are arranged to successively engage and push the teeth of the toothed discs to apply rotational torque to the engine shaft as the carrier reciprocates.
