An auxiliary air control valve for an internal combustion engine, which transmits the output of the actuator to the valve body, and is provided with a spring whose one end on the heat sensing portion side is always linked to the movement of the output rod or shaft of the actuator. . The brief description of the drawing has been amended as follows. "22, 38...valve body" on page 14, line 7 of the specification is corrected to "22, 39...valve body". "39...valve body" on page 14, line 9 of the specification is corrected to "38...valve seat.""Expansionvalve" on page 14, lines 9-10 of the specification is corrected to "thermal sensing section."

Claims

[Scope of utility model registration request]

a housing having a valve seat formed in an internal air passage connecting an air inlet and an air outlet connected to a bypass passage that detours around a throttle valve of the engine; An internal combustion engine comprising a valve body that is driven by an actuator that is activated by an operating parameter to control the passage area of the fluid passage in the valve seat, and a spring that is made of a shape memory alloy and biases the valve body in the valve opening direction. Auxiliary air control valve.
