Claims

[Claims for Utility Model Registration] (1) In a pressure reducing valve for two systems that has two pressure reducing valves that reduce the input pressure introduced from the first inlet and output it from the outlet, the pressure from the pressure generation source of each system a pair of second inlets that introduce pressure from each system; a piston that is slidable in the axial direction to receive the pressure of each system introduced from the second inlet so as to face each other in the axial direction; and a piston that is slidable in the axial direction; Consisting of a pair of bypass passages provided in each system connected in parallel with the pressure reducing valve and a pair of seal means for opening and closing this bypass passage, the pressure of each system introduced from the second inlet is substantially , the piston is held at the neutral position even if the pressures of the systems introduced from the first inlet are unequal, the bypass passages of each system are closed together by the sealing means, and the system is opened from the second inlet. The piston moves to the low pressure side only when the pressures of the introduced systems become uneven, so that the system sealing means on the high pressure side brings the bypass passage on the high pressure side into communication. A pressure reducing valve for two systems with failure compensation function, which is characterized by: (2) The operating position of the piston when the pressures of the respective systems introduced from the second inlet become uneven, and the operating position when the pressure of the respective systems introduced from the second inlet is unequal during depressurization. Claims for registration of a utility model characterized in that the system maintains its position and returns to the neutral position by the first pressurization when the pressures of each system introduced from the second inlet become substantially equal. A two-system pressure reducing valve with failure compensation function as described in item 1. (3) A cam surface is provided on the piston, and a part of the reciprocating switch is brought into contact with the cam surface, so that the switch detects the ON or OFF state based on the pressure difference in each system introduced from the second inlet. A two-system pressure reducing valve with failure compensation function as set forth in claim 1 or 2 of the utility model registration claim, characterized in that:
