The invention concerns a cam mechanism (10), in particular for the actuation of ventilation valves of a vehicle ventilation system with a revolving cam disc (12) which has on one of the disc faces two curvilinear guides (16, 18) intersecting in intersection areas (14) as well as two swivelling adjustment levers (20, 22) each with a coupling (24, 26) associated with a curvilinear guide (16, 18). For guiding at least one adjustment lever (20, 22) during its on passage through the intersection areas (14) separate guide elements (32a, 32b, 32c) different from the curvilinear guides (16, 18) and the couplings (24, 26) are provided. |
