Abstract
A liquid flow rate control valve is provided in which since a total area of overlapping sections of a communication hole group () of a distributor () and an outlet opening () of a sleeve () changes when the distributor () is rotated by a first electric motor (), if a rotor () is rotated by means of a second electric motor (), an input port () communicates with an output port () through an inlet opening () of the rotor (), the communication hole group () of the distributor (), and the outlet opening () of the sleeve () when the inlet opening () of the rotor () passes through the overlapping sections, thereby making it possible to carry out PWM control of a flow rate of liquid. Since a thrust load in an axis (L) direction does not act on the distributor () and the rotor (), supporting the distributor () and the rotor () becomes easy, thereby enabling the cost and weight to be cut.
