Patent attributes
A cooling-water control valve, which controls a flow rate of cooling water for an engine, includes a housing and a valve member. The housing has multiple outlet ports. The valve member is movably provided in the housing, so that it is rotatable around an axis line of the valve member. The valve member has multiple opened portions. Each of the opened portions is formed at a position, which is different from one another in an axial direction of the valve member. Each of the opened portions is operatively communicated to one of the outlet ports. The valve member changes a communication ratio between the opened portion and the outlet port depending on a rotational position of the valve member. The cooling-water control valve is provided at a position between the engine and an electric power converting device.
