Abstract (en)
A thermostat (1) for cooling system of an internal combustion engine (100) comprises a sensitive element (4) comprising a capsule (40) that contains a sensitive material (5) that changes its volume when it reaches a threshold temperature, an actuation rod (8) associated to the sensitive element (5) and connected to a shutter (3) suitable for closing/opening a flow of coolant from the radiator (104) towards the engine (100) of the vehicle; and cooling means (R) coupled with the sensitive element (4) to cool the sensitive material (5), delaying the opening of the shutter (3) of the thermostat valve (2), in such a way as to stabilize the coolant at a temperature higher than the threshold temperature of the sensitive material.
