the development of cooling system for internal combustion engines

摘要

A cooling device for internal combustion engines, comprises a radiator 4 which is connected respectively to the cooling chamber of the engine and to a circulation pump 6 itself connected to a cooling liquid expansion chamber 8, in which is maintained an air pressure greater than atmospheric pressure, wherein the expansion chamber 8 is connected to an air pump 10 generating a pulsated air pressure, said pump 10 being driven by means of an auxiliary member of the internal combustion engine.
