Abstract: PURPOSE:To enlarge an area and reduce pressure loss by slantly forming a communication hole for several shuttle valves in between adjacent charge holes and to prevent the leakage of operating fluid and improve responsibility by sealing spaces in a valve mainframe with respective sealing material. CONSTITUTION:A shuttle valve 47 compares the pressure of operating fluid flowing into an upper inlet port 38 with the pressure of operating fluid flowing into a lower inlet port 45 to output higher pressure from a middle outlet port 41 to a lower space 43. Operating fluid with higher pressure output to the lower space 43 flows into an upper space 42 in another shuttle valve 47 adjacent thereto via a communication hole 50 and is compared with operating fluid flowing from a pressure detection port 34. As a result, operating fluid is output to a pressure intake port 51. The communication hole 50 is slantly formed in between adjacent charge holes 31 in a valve mainframe 30. The pressure detection port 34 and the lower space 43 are sealed with sealing material 49, while the lower space 43 and the upper space 42 are sealed with another sealing material 48.
