Title: A THERMOSTAT DEVICE FOR A COOLING SYSTEM
Abstract:
The present invention relates to a thermostat device (8) for a cooling system cooling a combustion engine (2) and a further object (6). The thermostat device (8) comprises a first thermal expansion element (21) configured to be in thermal contact with coolant leaving a radiator (11) via a pilot line (14) and to provide a stroke of a valve body (16, 24) in response to said coolant temperature. The thermostat device (8) also comprises a second thermal expansion element (22) configured to be in thermal contact with the coolant leaving the further object (6). The second thermal expansion element (22) is able to provide a stroke of the valve body (16, 24) in response to this coolant temperature. The thermostat device is designed such that the valve body (16, 24) is moved to a position defined by the thermal expansion element (21, 22) providing the longest stroke.
