Drive to operate control vanes in motor vehicle heating, ventilation or air conditioning ducts, uses sliders attached to drive motor shaft running on annular tracks to supply motor, with tracks cut to provide control supply to motor

摘要

The actuator drive has an electric motor (15) with its output shaft (5) displacing air control vanes. The motor shaft drives sliders (6) which runs on annular tracks (1A-1C;2A-2C;3A-3C) formed on a printed circuit board. The supply to the electric motor is through the slider and the tracks. The tracks have a breaks at the appropriate positions to control the displacement of the vane.
