ABSTRACT:
Valves for an internal combustion engine are mounted for rocking movements about an axis perpendicular to a cylinder axis of the engine, and define passage portions extending perpendicular to their rocking axes so that they move between positions in which their passage portions form part of venturi-shaped inlet and exhaust passages, and positions in which they obturate the inlet and exhaust passages. The valve members may be rocked by a camshaft and mechanical linkages, or by actuators under computer control.
