Thermostat device

All the engines described are equipped with an engine thermostat 2101. The thermostat consists of a body and a cover, which are rolled together with the seat 8 of the main valve 9 (pic. 29), pressed by a spring 7. The thermostat has three pipes: inlet 13 inlet of cooled liquid from the radiator, inlet 1 inlet of hot fluid from the engine cooling jacket and outlet 6 for supplying fluid to the pump. The main valve 9 is pressed onto the cup 4, in which the rubber insert 5 is rolled. The rubber insert contains a polished steel piston 12 installed in the nut 11 of the fixed holder 10. Between the walls of the cup and the rubber insert there is a solid heat-sensitive filler 14. Two racks are fixed on the main valve 15, on which bypass valve 2 is installed, pressed by spring 3.
