When the position (D=-Max) starts moving again in the direction of the father, the liquid A of the chamber 4 is pressurized, and on the other hand, the liquid A of the chamber 3 is depressurized, and thus the liquid A passing through the chamber 58 of the check valve 16 is mainly utilized. The pressurization and the depressurization of the liquid A through the chamber 54 of the orifice 14 cause the valve body 51 and the valve seat member 57 to move in the direction of 82' and the main control valve body 75 is again shown in Figs. 1 and 8 Located in the central passage 91, the central passage 91 is closed to prevent the large-diameter passage % from communicating with the large-diameter passage 93 via the central passage 91, the expansion-diameter passage 94 and the %, and the flow of the liquid A to the chamber 3 side of the chamber 4 passes through the hole again. The port 7 is instead of the central passage 91, so that in the movement of the piston 28 from the maximum displacement position (D=_Max) in the X2 direction to the X i direction, the vibration energy absorbing device 1 produces the aperture 7 in the curve 124 of Fig. 10 117231-1010323.doc -19-

The reaction force R shown in S 1378191 is supplied to the piston rod 29β in the direction in which the valve seat member 57 is moved, and the liquid crucible is led out from the chamber 59 through the hole 68 to the large diameter passage 93. When the piston 28 continues to move in the magical direction from the substantially central position (D=〇) of the cylindrical portion 26, the liquid A of the chamber 58 is pressurized and the liquid A of the chamber 54 is depressurized thereby causing the valve body 5! and the valve seat member. 53 is accompanied by the reduction of the elastic mechanism 61 and the elongation of the elastic mechanism 62, and the large movement is again performed in the B2 direction, and as shown in FIGS. 4 and 9, the control wide body 79 is separated from the valve seat body 85, and The main control valve body 75 is separated from the t-channel 91, and is located on the side of the large-diameter passage 92 via the diameter-enlarged passage 94, the central passage 91 is opened, and the large-diameter passage % and the large-diameter passage 93 are passed through the central passage 91, the expansion-diameter passages 94 and 95. While communicating, the flow of the liquid A to the chamber 3 side of the chamber 4 is via the central passage 9 instead of the orifice 7, so that the vibration energy is absorbed in the movement of the piston 28 from the substantially central position (1 > = 0) to the magical direction. The device 1 supplies the piston rod 29 with a substantially zero reaction force R as indicated by the straight line 125 in Fig. 1 of the central passage 91. After the piston 28 is again moved to the maximum displacement position (D=+Max) in the X1 direction, the piston 28 repeats the above action in the vibrations limited to the X2 and XI directions, and the vibration energy absorbing device 1 will be the curve 122 and the straight line in FIG. The reaction force r formed by the damper ring shown by 123, curve 124 and line 125 is supplied to the piston rod 29. Then, in the vibration energy absorbing device, the amplitude and velocity of the vibration isolation structure 150 vibrating in the horizontal direction by the earthquake are reduced, and the vibration damping ring shown by the curve 122, the line 123, the curve 124, and the line 125 is reduced. The vibration damping effect of the damping ring is provided to the vibration of the seismic isolation structure 150 in the horizontal direction, and once the vibration of the isolation structure 150 subsides, the seismic isolation structure 150 can utilize the spiral. The restoring force of the spring 154 is configured with 11723M010323.doc -20· 1378191 in the initial position. During the vibration of the isolating structure 150, on the isolated structure 15〇, at the respective positions D of the piston 28 in the X direction, the return of the coil spring 154 represented by the restoring force line 130 as shown in FIG. The force r and the vibration energy absorb the reaction force R of the device 1, and the vibration energy absorbing device has a so-called negative stiffness with respect to the displacement of the position D of the vibration-isolating structure 150, so that the vibration-isolating structure ι5〇 is loaded. The combined force of the reaction force R of the vibration energy absorbing device 1 and the restoring force R of the coil spring is small, and thus the rigidity of the isolated structure 15 受到 subjected to such resultant forces is not particularly large. Further, in the vibration energy absorbing apparatus 1, a control valve 19 having a valve body 51 movable in the B direction is used, and the valve body 51 is moved in accordance with the relative movement of the partition member 5 with respect to the housing 2 in the X direction. And moving the position, and generating the fluid pressure supplied to the crucibles 15 and 18, thereby controlling the communication between the crucibles 1 and 12', so that the target action can be performed even in the event of a power failure, and the negative stiffness which does not have to occupy a large space can be formed. Small structure. In the above-described example, the vibration isolation structure 15 〇 is realized by the roller 153, and the vibration isolation structure 15 〇 can be placed on the floor 152 via a sliding member or the like to make the vibration isolation structure 150 can be moved in the horizontal direction η with respect to the ground 152. Further, for example, the vibration-isolating structure can also achieve vibration isolation by using a laminated rubber support pad. In this case, the coil spring 丨 54 can be omitted, and The laminated rubber support pad of the elastic device bears the recovery function, and the structure can also be a structure that is not subjected to the vibration isolation. In this case, it is not necessary to specifically set the recovery mechanism on the object other than the structure, or The structure itself has a recovery function. Also, the flow resistance at the orifices 7, 14, and 17

The best damping ring shown by curve 134 and line 125. Further, the curve shown in Fig. 10 is for explaining the principle curve. Actually, the curve 122 and the line 123 are not connected by the origin (=0), and the curve 124 and the line 125 are also the same.
