ABSTRACT:
A servo valve device in a power steering apparatus of an automobile includes a valve housing having a main valve rotatably mounted therein for rotating in response to the movement of a hydraulic power cylinder. A flap valve member is rotatably mounted in the main valve member for controlling the supply of fluid under pressure to a pair of distribution ports from a pair of injection ports. Each of the distribution ports separately communicates with a different one of the pair of injection ports through a pair of fluid passages formed in the main valve. One of the fluid passages is connected to one chamber of the hydraulic power cylinder through an annular recess formed on the peripheral portion of the main valve member, while the other of the fluid passages is connected to the other chamber of the hydraulic power cylinder through a passage formed within the flap valve.
