PURPOSE:To enable the arbitrary alteration and selection of sucking and jetting ports and the full-automatic performance of a full-scale supplying operation and supply quantity adjustment without manual handling, by using only one supply opening. CONSTITUTION:A supply opening A for air conditioning which is capable of varying the quantity of airflow can be varied for the direction of air supply according to the position of an internal cylinder damper 3. Thus, air is jetted, for instance, only from an upper air jetting port 2A and is supplied into a room through the outside section 7A of a diffuser 7, or otherwise, it is jetted only from a lower air jetting port 2B and supplied into the room through the inside section 7B of the diffuser 7. Moreover, when the cylinder damper 3 is moved so as to open both of the jetting ports 2A and 2B, air is jetted all at once from both of the ports 2A and 2B, and thus full-scale supply is conducted. The cylinder damper 3 is put by screwing on a threaded rod 4 disposed through a tubular body 1 along the axial direction thereof and can be moved for operation by the rotation of said threaded rod 4, while this rod 4 is moved vertically by a motor 6 which is controlled to drive by an indoor temperature detecting sensor 5. |
