摘要： A cylinder apparatus comprises a piston which is displaced along a cylinder tube under the driving action of a driving section provided for a main cylinder body, while the piston is displaced under the pressing action of a pressure fluid supplied to the cylinder tube. The amount of the pressure fluid supplied to the main cylinder body is increased before a workpiece is engaged with a table section arranged at an end of the main cylinder body so that pressing force, which is applied to the piston, is increased. Accordingly, driving load, which is exerted on the driving section when the workpiece is engaged with the table section, is reduced.
摘要翻译：气缸装置包括活塞，该活塞在为主缸体设置的驱动部分的驱动作用下沿着气缸管移动，同时活塞在供给到气缸管的压力流体的加压作用下移动。供给到主缸体的压力流体的量在工件与设置在主缸体的端部的工作台部件接合之前增加，使得施加到活塞上的按压力增加。因此，当工件与工作台部分接合时施加在驱动部分上的驱动负载减小。

摘要： Compressed air is introduced into a cylinder chamber to displace a piston closely to a target position. Then, a ball screw shaft is rotated about its own axis by an electric motor to inch the piston to the target position. Upon arrival of the piston at the target position, the ball screw shaft is stopped by a brake mechanism to hold the piston accurately in the target position. The drive shaft of the electric motor extends parallel to the ball screw shaft, thus reducing the entire length of a servo cylinder apparatus. Solenoid-operated directional control valves, for supplying compressed air to the cylinder chamber and the brake mechanism are coupled integrally to a cylinder assembly, so that pipes are shortened for allowing the piston to be displaced and stopped quickly and accurately.
摘要翻译：将压缩空气引入气缸室中以将活塞靠近目标位置。然后，滚珠丝杠轴通过电动马达绕其自身的轴线旋转，将活塞平移到目标位置。当活塞到达目标位置时，滚珠丝杠轴由制动机构阻止，以将活塞准确地保持在目标位置。电动机的驱动轴平行于滚珠丝杠轴延伸，从而减小了伺服缸装置的整个长度。用于将压缩空气供应到气缸室和制动机构的电磁操作方向控制阀一体地联接到气缸组件，使得管道被缩短以允许活塞快速且准确地移动和停止。
