PROBLEM TO BE SOLVED: To provide a damper opening and closing device capable of reducing a pressure loss of fluid flowing in a fluid passage.SOLUTION: A damper opening and closing device 10 comprises: an outer cylinder 1; an inner cylinder 2 which is arranged inside the outer cylinder 1, is movably supported by the outer cylinder 1 and has a fluid passage 7 on the inside; a damper group 30 constituted of a plurality of dampers 3 openably and closably arranged in the fluid passage 7; and angle control means for controlling inclination angles of the dampers 3 by interlocking with the movement of the inner cylinder 2 with respect to the outer cylinder 1. The plurality of dampers 3 cause inner peripheral edge parts 31b of the dampers to be opposed to one another and are swingably supported by the inner cylinder 2, respectively. The dampers 3 can adjust a flow quantity of fluid flowing in the fluid passage by changing the inclination angle to the axial direction of the fluid passage 7 by oscillation of the damper relative to the inner cylinder 2.SELECTED DRAWING: Figure 4

    【課題】 流体通路を流通する流体の圧力損失を低くすることができるダンパ開閉装置を提供する。【解決手段】 ダンパ開閉装置10は、外筒1と、外筒1の内側に配置されて外筒1に対して可動自在に支持されるとともに内部に流体通路7を有する内筒2と、流体通路7に開閉自在に配置された複数のダンパ3からなるダンパ群30と、外筒1に対する内筒2の移動に連動させて、ダンパ3の傾斜角度を制御する角度制御手段とを備える。複数のダンパ3は、互いに内周縁部31bを対向させて、それぞれ内筒2に揺動自在に支持されている。ダンパ3は、内筒2に対して揺動することにより流体通路7の軸方向に対する傾斜角度を変えることで流体通路を流通する流体の流通量を調整することができる。【選択図】 図4
