載の流量調節用ダンパー。1. In a damper that is rotatably mounted on a tact and can be held at a required opening degree within an angular range of 90 degrees, the surface where the fluid passing through the duct contacts the damper is an arcuate curved surface. A flow rate adjusting tamper 02 characterized in that the arcuate curved surface is configured such that the flow rate flowing through the space formed by the curved surface and the inner wall surface of the tactile chamber maintains a substantially proportional relationship with the opening degree of the tamper. The tamper-03 duct for flow rate adjustment according to claim 1, wherein the arcuate curved surfaces of the tact are curved surfaces with a small radius of curvature in the first half of the arc near the pivot shaft and a dog radius of curvature in the second half. The flow rate adjustment according to claim 1, wherein the arcuate curved surface is an arcuate surface, and has openings converging from both sides of the rotation shaft side to the center part of the opposite side forming a parapet line. damper.
