| 摘要 |
An air intake control device admitting preheated and/or cold air to the carburetor in response to changes in the air temperature, the device having a thermostat-controlled control flap pivoting between the intake openings of a cold-air duct and a warm-air duct, closing off the one or the other in its end positions. The control linkage includes a telescopically compressible push linkage with an overload spring and a pushinsensitive pull member pulled by the overload spring in its retracting node and connected to the control flap shaft at a greater pivot arm than that of the push linkage, so that the overload spring serves also as the return spring for the control flap. The control members are mounted on a removable frame inside the main intake duct.
