力士乐（rexroth）气缸--德国原装
力士乐气压传动中将压缩气体的压力能转换为机械 能的气动执行元件。气缸有做往复直线运动的和做往复摆动两种类型。
做往复直线运动的气缸又可分为单作用气缸、双作用气缸、膜片式气缸和冲击气缸4种。
①单作用气缸：仅一端有活塞杆，从活塞一侧供气聚能产生气压，气压推动活塞产生推力伸出，靠弹簧或自重返回。
②双作用气缸：从活塞两侧交替供气，在一个或两个方向输出力。
③膜片式气缸：用膜片代替活塞，只在一个方向输出力，用弹簧复位。它的密封性能好，但行程短。
④冲击气缸：这是一种新型元件。它把压缩气体的压力能转换为活塞高速（10～20米/秒）运动的动能，借以做功。
⑤无杆气缸：没有活塞杆的气缸的总称。有磁性气缸，缆索气缸两大类。
做往复摆动的气缸称摆动气缸，由叶片将内腔分隔为二，向两腔交替供气，输出轴做摆动运动，摆动角小于 280°。此外，还有回转气缸、气液阻尼缸和步进气缸等。
