<p>The subject of the invention is an adjustable pulley (1) comprising a ring (2) and a hub (14) to which is fixed the shaft, which is adjustable about the axis of rotation with respect to this ring (2), which last is improved by the presence of means of adjustment about the axis of rotation of the hub (14) with respect to the ring (2) comprising teeth (11) on the ring (2) and a pinion (23) which anchors itself to the hub (40) at a fixed position (22), the pinion (23) then co-operating with the teeth (11) and producing a continuous and reproducible rotation of the hub (14) with respect to the ring (2). The invention applies particularly to the adjusting of the orientation of a shaft used to control an automotive part, for example a camshaft controlling an injection pump. <IMAGE></p> |
