特徴とする定風量装置。 An outer cylinder for forming an outer shell is disposed in the outer cylinder with a gap between the outer cylinder and the outer cylinder, and the downstream end of the gap is closed, and the cylinder wall has an upstream side and a downstream side. an inner cylinder formed with a flow passage opening provided for communication with the wind pressure receiving plate, and a wind pressure receiving plate whose outer periphery is in sliding contact with the inner wall surface of the inner cylinder, and a wind pressure receiving plate guide rod arranged in the inner cylinder. In addition to supporting it in a movable manner,
A balancing spring for stopping the wind pressure receiving plate in equilibrium with the wind pressure is disposed on the downstream side of the wind pressure receiving plate, and the wind pressure receiving plate is moved in response to the wind pressure on the upstream side, and the wind pressure receiving plate is moved in response to the wind pressure on the upstream side. A constant air volume device comprising a valve body portion that changes the area provided for communication between an upstream side and a downstream side, and is characterized in that the air volume is made equal to a predetermined air volume even if the pressure on the upstream side fluctuates.
