摘要： Electrohydraulic thermostat system (8) for a filter device (1), comprising a main valve (10) and a pilot valve (9), wherein the main valve (10) comprises a valve body (23) which is arranged in a receiving section (29) of a housing (22), wherein the valve body (23) subdivides the receiving section (29) into a fluid distribution chamber (30), which is configured to distribute a working fluid (2) to an inflow line (15) of a component (14) for changing a temperature of the working fluid (2) and/or to a bypass line (21) for bypassing the component (14), and a control chamber (31), wherein the pilot valve (9) is configured to cause a pressure difference between the fluid distribution chamber (30) and the control chamber (31) as a function of the temperature of the working fluid (2) so that the working fluid (2) moves the valve body (23) in the receiving section (29) due to the pressure difference for opening and closing the inflow line (15) and/or the bypass line (21).
