ABSTRACT:
A Scotch yoke mechanism has a yoke frame with opposed parallel tracks engaged by rollers presented by a block assembly and is arranged to transmit power between a rotating crankshaft on a crankpin of which the block assembly is mounted and oppositely directed pistons mounted on the yoke frame, which moves linearly along a reciprocation axis. Two additional Scotch yoke mechanisms of the same type are presented by a cage surrounding the yoke frame and presenting two additional pistons opposing those of the first-mentioned Scotch yoke mechanism. The cage operates from two spaced apart crankpins which are aligned, and also moves linearly along the reciprocation axis.
