A recirculating valve according to the present invention comprises a fuel supplying passage in fluid communication with a fuel tank and an engine, a return passage in fluid communication with the engine and the fuel tank, a communication passage in fluid communication with the fuel supplying passage and the return passage. A temperature sensitive displacement portion that is provided in the fuel supplying passage and displaces in accordance with the fuel temperature. An on-off valve closes the communication passage when the fuel temperature in the fuel supplying passage is above a first prescribed temperature, and opens the communication passage when the fuel temperature in the fuel supplying passage is below a second prescribed temperature, in accordance with a displacement of the temperature sensitive displacement portion.

Recirculating valve

An electric power generating system for a vehicle includes a generator having a field coil, a voltage regulator, a temperature sensor for sensing temperature of the voltage regulator, a field current restricting circuit that directly restricts field current if temperature of the voltage regulator becomes higher than a maximum level and a device that prevents temperature of the voltage regulator from further rising without directly restricting field current if temperature of the voltage regulator becomes a warning level that is lower than the maximum level.
