<p>An arrangement for converting rotary motion of a camshaft (1) into linear motion of a reciprocable valve (9) employs a reciprocable cam (2) which is rotatable with the camshaft but is radially displaceable relative to the camshaft which extends through a slot-shaped aperture in the reciprocable cam. The profile of the reciprocable cam is held in engagement with a fixed reference roller (3) and the buchet (7) of valve (a) is held in engagement with output rings (4) in the cam. In the course of rotation of the camshaft, the cam lobe (21) causes radial displacement of the cam on the camshaft with attendant movement of the valve.</p> |
