Abstract

PURPOSE:To improve the control characteristic of a flow control damper provided in the flow path of a ventilation system, by providing the damper containing section obliquely against the flow while partitioning the containing section into plural chambers. CONSTITUTION:The casing arranged in series with the conduit of a ventilation system is shown by the referential number 10 in which a damper containing section 12 is fixed while a plurality of chambers 13a, 13b are formed by the flow path separating boards 14a, 14b and small capacity dampers 15a, 15b are equipped in each chamber. Each damper can vary the opening through an operating device. When employing manu small capacity dampers in such a manner, the rational relation between the damper angle and the flow can be maintained more linear than the conventional one.
