Abstract
The present invention relates to a thermostat arrangement for a cooling system for a combustion engine (2). The thermostat arrangement comprises an electrically controlled valve (12) configured to distribute a coolant flow rate between a radiator (9) and a radiator bypass line (10) in the cooling system, an actuator (13) configured to move the electrically controlled valve (12) to different valve positions in which it distributes different coolant flow rates in a stepless manner to the radiator (9) and the radiator bypass line (10), and a control unit (14) configured to determine a desired valve position of the electrically controlled valve (12) and to control the actuator (13) such that it moves the electrically controlled valve (12) to said desired valve position. The electrically controlled valve (12) is dimensioned to provide an adjustable coolant flow rate to the radiator (9) up to a certain flow rate limit. The thermostat arrangement comprises an additional valve (15, 16) which is designed to be automatically moved to an open position and provide an additional coolant flow rate to the radiator (9) when a threshold parameter value of the coolant is exceeded.
