る内燃機関の補助空気流量制御弁。 A valve body is provided in an auxiliary air passage that bypasses the throttle valve of the engine intake system, and the opening degree of the valve body is controlled in accordance with a drive signal output from a control device to control the passage area of the auxiliary air passage. An auxiliary air flow rate for an internal combustion engine, which is configured to control the air flow rate of an internal combustion engine, and includes an air flow rate regulating means that regulates the maximum air flow rate of the auxiliary air passage in conjunction with a temperature-sensitive member that detects the engine temperature and undergoes thermal displacement. The control valve includes an actuator having a diaphragm operated by negative pressure generated in the intake passage, and the diaphragm is interlocked with the air flow rate regulating means so as to increase the maximum air flow rate when negative pressure is generated. An auxiliary air flow control valve for an internal combustion engine, characterized in that:
