Abstract
An oil passage change-over valve allows an alternate communication from a first opening portion in one side a second and a third opening portion provided in another side to be changed over. A first opening portion is formed in one side of a valve body and the second and third opening portions are formed in another side of the valve body; a valve element within a valve hole of the valve body; and a communicating oil passage is formed in the valve element for alternately communicating the three opening portions. Inside the valve body, there are formed a first oil passage for connecting the valve hole with the first opening portion, a second oil passage for connecting the valve hole with the second opening portion, and a third oil passage for connecting the valve hole with the third opening portion deviated by 120 degrees from the first oil passage, respectively.
