摘要： PROBLEM TO BE SOLVED: To prevent establishing of an unintentional drive stage at switching of drive stages, and to provide a variable valve mechanism which is superior in a switching response of the drive stages.
SOLUTION: Oil pressure to a first hydraulic supply passage 10a is supplied with a designated time difference t1 after oil pressure to a third hydraulic supply passage 10c is released. Then, a first connection pin 13a starts to slightly enter into a first guide hole 11a by repulsion force of a compressed coil spring 12a as illustrated in the figure 8(a) when oil pressure (namely, oil pressure applied to a second guide hole 11b) to the third hydraulic supply passage 10c is released. Further, a first connection pin 13a is pushed into the first guide hole 11a as illustrated in the figure 8(b) when oil pressure to the first hydraulic supply passage 10a is supplied, and an end of a second connection pin 13b starts to enter into a second guide hole 11b.

摘要： PROBLEM TO BE SOLVED: To increase the degree of freedom of the layout of a fluid-pressure actuator in which a rod is fixed to a piston slidably fitted to a cylinder.
SOLUTION: The axis L1 of the rod 76 fixed to the piston 75 and slidably guided by a guide member 77 is deviated from the axis L2 of the piston 75 slidably fitted to the cylinder 74. Accordingly, the degree of freedom of the arrangement of the fluid-pressure actuator 64 can be increased more than a case where the axis L1 of the rod 76 is aligned with the axis L2 of the piston 75. Also, since the piston 75 and the rod 76 formed separately from each other are joined to each other through an O-ring 82, the rod 76 can be moved relative to the piston 75 due to the deformation of the O-ring 82. Thus, the piston 75 can be smoothly operated by absorbing the displacement of the axis of the guide member 77 from the axis of the rod 76.

摘要翻译：要解决的问题：为了增加其中杆被固定到可滑动地装配到气缸的活塞的流体压力致动器的布局的自由度。解决方案：固定到活塞75上的杆76的轴线L1被引导构件77滑动地引导，偏离可滑动地装配到气缸74的活塞75的轴线L2。因此，流体压力致动器64的布置可以比杆76的轴线L1与活塞75的轴线L2对准的情况更多。另外，由于活塞75和彼此分开形成的杆76是通过O形环82彼此连接，由于O形环82的变形，杆76可以相对于活塞75移动。因此，可以通过吸收活塞75的轴线的位移来平滑地操作活塞75 引导构件77从杆76的轴线起。版权所有（C）2006，JPO＆NCIPI
