A three-way flow control valve for refrigeration cycles having two parallel heat exchangers is disclosed. This valve is designed to selectively feed refrigerant to both heat exchangers, or one of the two heat exchangers as desired. The three-way flow control valve of this invention consists of a hollow cylindrical casing opened at its first and second ends. A first valve housing is held in the first end of the casing, and is provided with a first refrigerant outlet and a first orifice formed in the first refrigerant outlet. A second valve housing is held in the second end of the casing, and is provided with a refrigerant inlet and a second refrigerant outlet, and a second orifice formed between the refrigerant inlet and the second refrigerant outlet. A first valve means is axially set within the first valve housing so as to be axially movable to control the opening ratio of the first orifice. A second valve means is axially set within the second valve housing so as to be axially movable to control the opening ratio of the second orifice. An actuation means is set between the first and second valve housings while allowing the two valve housings to communicate with each other, and actuates the first and second valve means.
