A reciprocating piston engine, pump or compressor including a crank-shaft having a crank-pin offset laterally from the axis of rotation of the crank-shaft, a connecting-rod pivotally-mounted on the crank-pin and pivotally-connected at the end thereof remote from the crank-pin to a piston, the axis of pivoting of the connecting-rod on the crank-pin being offset laterally from the longitudinal axis of the crank-pin, a non-rotatable gear mounted co-axially of the crank-shaft axis of rotation and a rotatable gear wheel mounted co-axially on the crank-pin for rotation thereon and in mesh with said non-rotatable gear, the connecting-rod being mounted on the rotatable gear for pivoting about an axis offset laterally from the longitudinal axis of the crank-pin, whereby the axis of pivoting of the connecting-rod on the crank-pin follows a predetermined locus as the crank-shaft is rotated.
A reciprocating piston machine including a cylinder, a piston reciprocatable therein, a crank-shaft, a crank-pin offset laterally from the axis of rotation of said crank-shaft, a connecting-rod pivotally-mounted on said crank-pin and pivotally-connected at the end thereof remote from said crank-pin to said piston, the axis of pivoting of said connecting-rod on said crank-pin offset laterally from the longitudinal axis of said crank-pin, and means constraining the axis of pivoting of said connecting-rod on said crank-pin to follow a predetermined locus as said crank-shaft is rotated, said constraining means comprising a non-rotatable gear mounted co-axially of the crank-shaft axis of rotation and a rotatable gear wheel mounted co-axially on said crank-pin for rotation thereon and in mesh with said non-rotatable gear, said connecting-rod mounted on said rotatable gear to pivot about an axis offset laterally from the longitudinal axis of said crank-pin.
