VENTILATION CONTROL DEVICE FOR VEHICLE HEATING AND/OR AIR CONDITIONING SYSTEM Russian patent published in 2016 - IPC B60H1/00 

FIELD: machine building.

SUBSTANCE: invention relates to a control device for the ventilation system of heating and / or air conditioning of the vehicle. Apparatus includes air distribution valve (9) for controlling the air flow, cam ring (1) having at least one guide cam (11) operatively connected to air distribution valve (9) for setting the damper to a position corresponding to the angular position of cam disc (1), which can be set by the actuator, and having mechanical end stop (21) cooperating with mechanical counterstop to determine the initial position of the actuator. Mechanical counterstop (23) is mounted movably and can be activated by additional actuator (13) selectively displacing counterstop (23) in the operating position, wherein end stop (21) of cam disc (1) can rest against mechanical counterstop (23), or a neutral position in which end stop (21) of cam disc (1) can rest against mechanical counterstop (23).

EFFECT: achieved is an improvement of the ventilation control, with the exception of unforeseen conditions and reduced wear of the device.
