  • Pressurization device for the cooling system of a heat engine
    Patent number: 4478178
    Abstract: This invention has as its object a pressurization device for a cooling system of a heat engine. According to the invention, the device (10) includes two pressure relief valves (20, 30) mounted in a series, a chamber (32) between the pressure relief valves (20, 30), and a source (34) of gas under pressure connected to the chamber (32). The expansion chamber (12) is not subjected to the scavenging of the pressurization gas, and the maximum value of the pressurization is equal to the sum of the values of the calibrations of the two pressure relief valves (20, 30).
