Abstract
PURPOSE: To reduce the decompression action of the system left when one system fails and enable decompression operation starting point to be controlled in normal state by pressing with single operation-starting point brake force from one end.
CONSTITUTION: The first piston 10 and the first valve part 11, and the second piston 20 and the second valve part 23 are arranged, and the valve part 11 is opened and closed according to the relative distance of both pistons 10 and 20, and the valve part 23 is opened and closed according to the relative distance between the piston 20 and the end wall, and the input pressure and the outpt pressure operation areas of the first system and the second system which opposes on the second piston 23 are formed equal. Therefore, in normal state, equal decompression forces act on to both systems, with the operation starting point control force F. When one system fails, decompression action can be reduced, compared to the normal state, through opening and closing of the valve of the system left. As decompression action starting point can be controlled in normal time, and the fixed operation starting point can be controlled. The valve can be used as a fixed operation starting point type control valve or a load response type control valve in utilization of the vertical displacement of a spring (not shown in the figure).
