| 摘要 |
The invention concerns a pneumatic servomotor using as reaction members a plurality of balls (15) enclosed between three bearing faces (12, 13, 14), the first bearing face (12) consisting of a projecting surface and at least partially conical of the servomotor plunger (9). The invention is characterised in that the first bearing face (12) has at least two different slopes (P1, P2) for decreasing the reaction force in case the servomotor is rapidly actuated. |
