Abstract

A variable valve timing mechanism for a camshaft comprises a sleeve 1 mounted via straight splines 4 to a camshaft has external helical splines engaging within a camshaft timing belt 5 pulley 3. Axial sleeve movement 12 causes rotation of the camshaft relative to the crankshaft. Axial movement is caused by a vacuum cylinder 7 connected to the engine inlet manifold acting on a lever 9 via a fulcrum 10 and engaging a groove in sleeve hub 11. The cylinder may alternatively be directly connected to the sleeve (Fig. 2b). In an alternative arrangement straight splines are formed on a shaft (16) separate to the camshaft and connected thereto by a pulley (17), belt (5) and further pulley. An externally helically splined axially movable sleeve (15) meshes with a helical crankshaft gear (18).
