Cooling circuit for motor vehicle internal combustion engine includes two cooling loops, one of which includes radiator, with loops having valves for controlling cooling fluid flow in opposite senses

摘要

The cooling circuit includes at least a first and second cooling loop separate from exterior recirculation or re-injection, mounted in parallel on an integral cooling device. The second loop is integral with a vehicle radiator. Each of the cooling loops includes a regulation element such as a valve (8,8') that is controlled as a function of temperature for controlling fluid flow in the loops, with the two valves being coupled together in a manner so as to be controlled in opposite or inverse senses. A Independent claim is included for a process for regulating cooling fluid circulation in the vehicle IC engine cooling circuit.
