Title: Fan coupling device for internal combustion engine
Inventor: HARIMA TOSHIO
IPC: F16D35/00
Filed: 1987-02-27
Abstract: PURPOSE:To prevent over cooling of an engine and to eliminate occurrence of droppage of output or noise by constructing a fan coupling device such that a communication hole through a partition board is opened/closed from inside and outside ends by means of a valve plate, thereby controlling rotation of housing according to the temperature of air. CONSTITUTION:When cooling of engine is started with low temperature of air in the vicinity of a bimetal 13, a valve plate 23 is held at a position where a communication hole 12 is closed by means of an arm 21. Consequently, quantity of working fluid flowing from a storage chamber 8 to a working chamber 9 decreases to lower torque being transmitted to a housing 3. When the temperature of air near the bimetal 13 exceeds over a setting level, the other side of the valve plate 23 opens the communication hole 12 gradually from the inside end as the arm 21 rotates. Consequently, quantity of working fluid flowing from the storage chamber 8 to the working chamber 9 can be regulated according to the temperature of air, and the rotation of the housing 3 can be controlled with high accuracy. As a result, over cooling of engine can be prevented reliably, useless rotation of the housing 3 can be prevented and occurrence of droppage of output or noise can be eliminated.
