A cylinder with cross inlet and exhaust ports contains a combination piston and rod having on its piston end a piston head or face and slidably attached sealing sleeve, and its other end is rotatable via a rod bearing attached to a crankshaft. The rotational motion of the rod with the crankshaft imparts an undulating movement to the piston head during its stroke motion and, in unison with the slidably attached sealing sleeve, effects a sequence wherein the exhaust ports open ahead of the inlet and close before the inlet closes. |
