摘要

The mechanism to set the position of a flap (12), in the air flow channel of a vehicle air conditioning system, has a drive motor (16) to rotate a threaded rod (20). The rotating thread moves a pin (24) along an axial guide (26) to engage the slide to move the keyed flap into the required alignment. The slide unit has a groove (32) on the inner side of the flap hub (28).
