The clutch which has the entry component which functioning is done it is not as a computer and the cover supporting the sealing component to have the viscous type fan

摘要

PROBLEM TO BE SOLVED: To provide a simplified viscosity fan driving system.;SOLUTION: The clutch-free viscosity fan driving system is formed, and a main body 14 of the fan driving device 10 is directly mounted on an input shaft 12 and rotated at a complete input speed. A sealing member 24 is pressed to the cover by an output driving part, and sealed to a seal ring 28 in the main body. This fan driving device is constituted without mounting the clutch, and the heat is not stored inside of a viscous fluid chamber between the main body and the cover. The main body rotates the input shaft at the complete input speed, thus the air flow passing through a main body-side fin is improved, and the cooling performance in driving the fan is improved.;COPYRIGHT: (C)2006,JPO&NCIPI
