Cooling systems for internal combustion engines

Claim 1

IN A SYSTEM FOR COOLING AN INTERNAL COMBUSTION ENGINE HAVING A COOLING JACKET AND A COMPRESSOR DRIVEN BY THE ENGINE EXHAUST FOR SUPERCHARGING SAID ENGINE, THE COMBINATION COMPRISING: INDEPENDENT FIRST AND SECOND COOLING LIQUID CIRCUITS; SAID FIRST COOLING LIQUID CIRCUIT INCLUDING A FIRST AIRCOOLED RADIATOR, A FIRST PUMP AND FIRST CONDUIT MEANS INTERCONNECTING SAID FIRST RADIATOR, SAID FIRST PUMP AND SAID COOLING JACKET TOGETHER TO FORM A CLOSED CIRCUIT IN WHICH SAID FIRST PUMP CIRCUATES COOLING LIQUID THROUGH SAID FIRST RADIATOR AND SAID COOLING JACKET; SAID FIRST COOLING LIQUID CIRCUIT FURTHER INCLUDING PRESSURIZING MEANS THEREIN FOR CREATING A SUPERATMOSPHERIC PRESSURE ON THE COOLING LIQUID THEREIN TO PREVENT THE FORMATION OF STEAM WITHIN SAID CIRCUIT; SAID SECOND COOLING LIQUID CIRCUIT INCLUDING A SECOND AIR-COOLED RADIATOR, COOLER MEANS COUPLED BETWEEN SAID COMPRESSOR AND SAID ENGINE, A SECOND PUMP AND SECOND CONDUIT MEANS INTERCONNECTING SAID SECOND RADIATOR, SAID SECOND PUMP AND SAID COOLER MEANS TOGETHER TO FORM A CIRCUIT IN WHICH SAID SECOND PUMP CIRCULATES COOLING LIQUID THROUGH SAID SECOND RADIATOR AND SAID COOLER; SAID SECOND CIRCUIT COOLING LIQUID BEING MAINTAINED AT A PRESSURE AND TEMPERATURE LOWER THAN THAT OF SAID FIRST CIRCUIT COOLING LIQUID; SAID FIRST AND SECOND RADIATORS BEING DISPOSED IN SPACED PARALLEL JUXTAPOSITION; AND MEANS ADJACENT SAID SECOND RADIATOR POSITIVELY PRODUCING A COOLING AIR STREAM WHICH INITIALLY FLOWS ACROSS SAID SECOND RADIATOR AND THEREAFTER FLOWS ACROSS SAID FIRST RADIATOR, THEREBY ASSURING THAT SAID SECOND CIRCUIT COOLING LIQUID TEMPERATURE IS MAINTAINED LOWER THAN SAID FIRST CIRCUIT COOLINF LIQUID TEMPERATURE
