The present invention relates to a coolant valve which comprises: a valve mainframe which includes a first inlet into which coolant is selectively introduced from a first heat exchanger, a second outlet through which the coolant is discharged to a first subject, a second inlet through which the coolant is introduced from a second heat exchanger, a second outlet which discharges the coolant to a second subject, and a third inlet which is branched from an exit of the first subject, and through which the coolant is selectively introduced; a first conversion means whose one side communicates with one of the first outlet and the second outlet, and whose other side communicates with one of the second inlet and the third inlet; and a second conversion means whose one side communicates with the other of the first outlet and the second outlet, and whose other side communicates with one selected from among the other of the second inlet and the third inlet and the third inlet. In accordance with the present invention, the coolant valve is able to compose all flow paths of a four-way valve and a three-way valve as a single integrated coolant valve, and reduce the cost of a whole product.

    본 발명은, 제1열교환기로부터 선택적으로 냉각수가 유입되는 제1유입구와, 제1대상물로 냉각수가 토출되는 제1토출구와, 제2열교환기로부터 냉각수가 유입되는 제2유입구와, 제2대상물로 냉각수가 토출되는 제2토출구와, 상기 제1대상물의 출구로부터 분기되어 냉각수가 선택적으로 유입되는 제3유입구가 형성된 밸브본체; 일 측이 상기 제1토출구와 상기 제2토출구 중 어느 하나와 연통되고, 타 측이 상기 제2유입구와 제3유입구 중 어느 하나와 연통되는 제1전환수단; 및 일 측이 상기 제1토출구와 상기 제2토출구 중 다른 하나와 연통되고, 타 측이 상기 제2유입구와 제3유입구 중 다른 하나 및 상기 제3유입구 둘 중에서 선택된 것과 연통되는 제2전환수단을 포함하는 냉각수 밸브를 제공한다. 본 발명에 따른 냉각수 밸브에 의하면, 하나의 통합된 냉각수 밸브로서 4웨이 밸브와 3웨이 밸브의 유로를 모두 구성할 수 있으며, 전제 제품의 원가를 절감할 수 있다.
