  • Air-conditioning duct apparatus with twistable duct vanes
    Patent number: 4991496
    Abstract: An air-conditioning apparatus for adjusting the direction and quantity of air comprises a duct device forming an air passage passing through the duct device, and an airflow adjusting device. The airflow adjusting device is made from a single thin plate and fitted to the duct device across the air passage to adjust a flow of air. Slits of predetermined patterns are formed on the airflow adjusting device to define a plurality of vanes which are integral to the airflow adjusting device.
    Type: Grant
    Filed: August 14, 1989
    Date of Patent: February 12, 1991
    Assignee: Kabushiki Kaisha Kyoritsu
    Inventors: Toshio Kuno, Yoshikazu Shindo, Yukio Kuno, Takeshi Ueno, Akira Torimi, Yoji Mori

  • Air-conditioning apparatus
    Patent number: 4876952
    Abstract: An air-conditioning apparatus for adjusting the direction and quantity of air comprises a duct device forming an air passage passing through the duct device, and an airflow adjusting device. The airflow adjusting device is made from a single thin plate and fitted to the duct device across the air passage to adjust a flow of air. Slits of predetermined patterns are formed on the airflow adjusting device to define a plurality of vanes which are integral to the airflow adjusting device. Functions for adjusting the direction and quantity of air are basically realized only with the single thin plate so that the material and manufacturing costs of the apparatus will be reduced, the transportation, installation and maintenance of the apparatus simplified, and angles of the vanes adjusted separately and freely.

  • Damper
    Patent number: 4790237
    Abstract: A damper for use in controlling the flow rate or direction of a flow of air or fumes flowing out from a room or space or flowing through a ventilation system, including a housing having at least one inlet opening. The housing has a tubular side wall in which are provided a plurality of outlet apertures opened and closed by associated closure members which are adapted to swing to and away from the side wall, preferable inwardly of the housing. The total flow area of the outlet apertures may be extended to a desired degree by increasing the axial length and diameter of the side wall of the housing, whereby the flow resistance and pressure drop across the damper are reduced.
