Claims

[Scope of utility model registration request]

This is for 02 control that automatically controls the residual 02 value in combustion exhaust gas, and includes a fuel control arm connected to a fuel valve that is driven to a desired angle by a master controller, and a fuel control arm that is coaxial with the drive of this fuel control arm. In an air-fuel cam that basically matches the increase and decrease characteristics of fuel and air, the air-fuel cam has an air control arm connected to an air damper that is guided by a simultaneously driven cam and driven to a desired angle. The control arm is configured such that both the first and second air control arms can be freely bent into a dogleg shape, and an appropriate position between both ends of the second air control arm is supported by an operating rod of an operating device to control 0°. 02 is characterized in that the air damper can be independently adjusted to open and close at any time.
