Cooling water control valve apparatus

摘要

Provided is a cooling water control valve apparatus capable of independently controlling flow rates of cooling water in two lines with a single apparatus for cooling water control and capable of achieving cost reduction. A cooling water control valve apparatus 10 which adjusts a flow rate of cooling water for cooling an object to be cooled includes two inlet ports 22, 22a through which cooling water is introduced, an electrical control valve 11 which is arranged at a first passage 23 communicated with one of the inlet ports and which adjusts a flow rate of cooling water flowing through the first passage 23 with electronic control, and a thermosensitive valve 40 which is arranged at a second passage 25 communicated with the other of inlet ports and which adjusts a flow rate of cooing water flowing through the second passage 25 owing to displacement of a temperature detecting medium 42 with temperature.
