Abstract

Improvements introduced in the cooling circuits of internal combustión engines of the type comprising an expansion vessel equipped in its upper part with a steam overpressure arrival orifice and a filling hole of the cooling liquid circuit, normally sealed by a plug provided with a torada valve that ensures the maintenance of the internal pressure of said refrigeration circuit in a range of determined values, and in its lower part of a communication outlet with said refrigeration circuit, which comprises a main circuit of cooling of the motor by fluid circulation pump driven by the motor and radiator with interposition of a thermostatic valve, and mounted in parallel with this main circuit, at least one auxiliary circuit, such as a heating circuit of the carburetion and intake system of the engine, and heating and demisting circuit by air heater d in the vehicle cabin driven by this motor, said circuits, main and auxiliary, in its upper part a purge hole of gaseous elements, the exit orifice of the expansion vessel being connected to the return pipe of the main circuit, between the base of the radiator and the suction hole of the pump and the purge holes of the gaseous elements of the different circuits are connected to the steam overpressure inlet hole located at the top of the expansion vessel, above the liquid level contained in this vessel, by a set of ducts comprising each nozzle of determined diameter, gathered in a monobloc assembly, of molded plastic material, which forms a multiple connection, and which comprises a single starting duct towards the expansion vessel, duct in which said nozzles discharge, characterized by the fact that the radial implantation, in the starting conduit of the multiple connection of the nozzle of the heating circuit by aerotherm is displaced relative to that of the nozzle of the main cooling circuit, which likewise radially opens into this starting duct upstream of said nozzle of the heating circuit and slightly waters below the nozzle of the heating circuit of the carburetion system, and of intake, which empties axially in this starting duct towards the expansion vessel.
