<p>PROBLEM TO BE SOLVED: To provide a tournament oil passage constituting device which has fast responsiveness and can be downsized. SOLUTION: This device are formed out of a plurality of shuttle valve holes 40a and a connecting grooves 90 continuing to the shuttle valve holes 40a on either one of fitting surfaces of laminated oil passage plates 60 to 67. A shuttle valve 40 is put in the shuttle valve hole 40a, and phase-in oil passages 68, 69 which lead to the shuttle valve hole 40a are formed on both of a oil plate 62 formed with the shuttle valve hole 40a and a oil plate 63 having a fitting surface on the shuttle valve hole 40a side, then, of the pressure oil phased in the both phase-in oil passages 68, 69, a high pressure oil is selected with the shuttle valve to be guided into the connecting groove 90. In this case, this devise comprises a plurality of main passages 51 to 54 which penetrates the plural laminated oil plates and do not intersect each other, and branch grooves 80 to 85 branched off from the main passage, and makes the branch grooves 80 to 85 communicate to the phase-in oil passages 68, 69.</p> |
