| 摘要 |
The invention relates to a device for supporting and guiding a mobile element in rotation about an axis, for example a piston 14 with circular movement oscillating about the rotational axis 12. The piston 14 is carried by a component 18 whose ends are connected to a stationary component 26 by two flexion strips 22, 24 which extend perpendicularly to the axis of rotation 12 and whose longitudinal axes intersect on this axis. The invention applies especially to frictionless compressors and to robotics. <IMAGE>
