Abstract

PURPOSE:To prevent loosening and fluttering of a radiator shutter by installing, on one side of the radiator, a torsion coil spring having a shaft built-in and installing, on the other side, an air motor driven by the air which is supplied in accordance with the temperature of the cooling water. CONSTITUTION:A casing 4 equipped with an opening port 3 in correspondence with the front surface of a radiator 1 is installed on the front surface of the radiator 1, and a radiator shutter taking-up part consisting of a fixed shaft 8, torsion spring 14, and a rotatable hollow shaft 9 is stored on one side of the casing 4. On the other side, is stored an air motor which consists of a hollow shaft 12 into which air is jetted-out from an air pump, when the temperature is low, through a temperature switch 16 and a solenoid valve 18, and further a hollow shaft 13 which is rotatably installed around the hollow shaft 12 and equipped with vanes 15 inside. When the temperature is low, the wire fitted on a radiator shutter 12 is taken-up onto the hollow shaft 13 to cover the front surface of the radiator.
