Abstract

A camshaft (26) has a vane (60) secured to an end thereof for non-oscillag rotation therewith. The camshaft also carries a sprocket (32) which can rotate with the camshaft (26) but which is also oscillatable with the camshaft (26). The vane (60) has opposed lobes (60a, 60b) which are received in opposed recesses (32a, 32b), respectively, of the sprocket (32). The recesses have greater circumferential extent than the lobes (60a, 60b) to permit the vane (60) and sprocket (32) to oscillate with respect to one another, and thereby permit the camshaft (26) to change in phase relative to a crankshaft whose phase relative to the sprocket (32) is fixed by virtue of a chain drive (38) extending therebetween.
