Abstract: <P>PROBLEM TO BE SOLVED: To enhance an accuracy of hydraulic control by a three direction switching type rotary control valve.  <P>SOLUTION: When an inner rotor 62 is rotated under such a condition that oil path ports 75a, 75b of an outer rotor 61 are closed by partition wall pins 83 of the inner rotor 62, the positions of the oil path ports 75a, 75b and the partition wall pins 83 are displaced from each other so that control groove portions 81b1, 81b3 of the inner rotor 62 are opposed to pressurized oil delivery ports B. Pressurized oil from a pressurized oil port P is supplied from the openings formed by the positional displacement, and supplied from connection grooves 84 to the control groove portions 81b1, 81b2, and then supplied from the oil path port 75b to A ports of an actuator. If feedback is arranged to be performed, the outer rotor 61 rotates following the inner rotor 62. When the rotation angles of both the rotors 62, 61 coincides with each other, the oil path port 75b is closed by the partition wall pin 83, thereby stopping the supply of the pressurized oil to the actuator.  <P>COPYRIGHT: (C)2009,JPO&INPIT
