Abstract:
1. A flow control valve, comprising: a main body provided with a first port which is connected with a supplying pipe of a heat exchange medium supplying part, second and third ports which are respectively connected with first and second heat exchanging regions of a heat exchanger so that heat exchange medium introduced through the first port is independently flowed in each of the first and second heat exchanging regions, a fourth port which is connected with a discharging pipe so as to discharge the heat exchange medium bypassed and discharged from the heat exchanger, a first flowing part in which the heat exchange medium is flowed and which is communicated with a part of the first port, a second flowing part through which the fourth port is passed and which is communicated with the rest of the first port, a third flowing part which is connected with the second and third ports, a fourth flowing part which is surrounded by the first to third flowing parts and connected with the fourth port, a partition wall which partitions the first to fourth flowing parts, a first communicating hole which is formed at a portion of the partition wall defining the first and third flowing parts, a second communicating hole which is formed at a portion of the partition wall defining the first and fourth flowing parts, a third communicating hole which is formed at a portion of the partition wall defining the fourth and second flowing parts, and a fourth communicating hole which is formed at a portion of the partition wall defining the second and third flowing parts; a first plate valve which is provided at the first flowing part so as to selectively open and close the first and second communicating holes; and a second plate valve which is provided at the second flowing part so as to selectively open and close the third and fourth communicating holes, wherein the partition wall is formed so that the first port is equally divided by the partition wall and then communicated with each of the first and second flowing parts, wherein the partition wall is extended into the fourth flowing part so as to equally divide the fourth port and partition the fourth flowing part, such that the heat exchange medium introduced through the second communicating hole into the first flowing part and the heat exchange medium introduced through the third communicating hole into the second flowing part are independently separated from each other, and wherein the partition wall is extended so as to partition the third flowing part into two parts, the second port being communicated with one part of the third flowing part and the third port being communicated with the other part of the third flowing part.
