Air control device for vehicle or room air conditioning system has actuator that constantly moves control element between relative positions, in which it is static for dwell time, depending on clocked signal

摘要

The device has a control element between at least one air inlet and output chamber and movable between two relative positions by an actuator to control a connection between one or more air input and output chambers. The actuator constantly moves the control element between at least two relative positions, in which it remains static during a dwell time associated with one of the relative positions, depending on a clocked PWM control signal. The device has a control element (16;24;29) arranged between at least one inlet (11;6-7;4) and output (13-15;11;5-7) air chamber and movable between two relative positions by an actuator (30) to control a connection between one or more input and one or more output air chambers. The actuator constantly moves the control element between at least two relative positions, in which the control element remains static during a dwell time associated with one of the relative positions, depending on a clocked PWM control signal. AN Independent claim is also included for the following: an air conditioning system, especially for a motor vehicle, with at least one inventive device.
