摘要： A rodless pneumatic cylinder includes main exhaust ports defined by the open ends (10, 11) of a pair of fixed tubular members (8, 9) that extend, respectively, into the cylinder body (1) from its opposed ends (2, 3). The main piston 14 of the rodless cylinder has an axial bore (18) formed in it in which is slidably mounted a small piston (19) that serves mutually to isolate the working chambers (16, 17) of the cylinder. The bore (18) carries seals (20, 21) adjacent to its opposed ends whereby, during motion of the piston (14), the bore (18) sealingly receives one or other of the tubular members (8, 9) at a pre-determined stage during the motion thereby effectively closing the main exhaust port (10 or 11). During further motion of the piston (14), air can, therefore, exhaust only through a throttled auxiliary exhaust port (12, 13) and such further motion of the piston (14) is thus cushioned.
The arrangement provides for a greater extent of cushioning relative to known arrangements in which the working chambers (16, 17) are mutually isolated by a barrier fixedly secured in the bore (18).
摘要翻译：一种无杆气压缸包括主排气口，主排气口由一对固定管状件（8,9）的开口端（10,11）限定，所述固定管状件分别从其相对端（2,3）延伸到缸体（1））。无杆气缸的主活塞14具有形成在其中的轴向孔（18），其中可滑动地安装有用于相互隔离气缸的工作室（16,17）的小活塞（19）。孔（18）带有与其相对端相邻的密封件（20,21），由此在活塞（14）运动期间，孔（18）以预先密封的方式密封地容纳管状件（8,9）中的一个或另一个在运动过程中确定的阶段，从而有效地关闭主排气口（10或11）。因此，在活塞（14）的进一步运动期间，空气可以仅通过节流的辅助排气口（12,13）排出，并且因此活塞（14）的这种进一步的运动被缓冲。与其中工作室（16,17）通过牢固地固定在孔（18）中的隔板相互隔离的已知布置相比，该布置提供了更大程度的缓冲。

摘要： A double-acting pneumatic cylinder is characterised by the provision of a pair of sealing elements (20,21 and 27,28) respectively located on either side of the piston (4) by means of rods (19 and 23,24) slidably mounted in longitudinal bores formed in the piston (4). At the commencement of the cylinder's in-stroke, the rod (19) and its associated sealing element (20,21) is in an extended position and serves to seal off the main exhaust port (13',14') while the piston (4) is still relatively distantly located from the end of its in-stroke. During further in-stroking the piston (4), air can therefore exhaust only through the auxiliary exhaust port (15') and the motion is thus cushioned. The out-stroke of the cylinder is similarly cushioned over a relatively large distance by virtue of the sealing element (27,28) adopting an extended position and closing off the main exhaust port (13,14), the air exhausting through the auxiliary exhaust port (15).
摘要翻译：双作用气动缸的特征在于，通过杆（19和23,24）分别设置在活塞（4）的任一侧上的一对密封元件（20,21和27,28），其可滑动地安装在活塞（4）中形成的纵向孔中。在缸的中行程开始时，杆（19）及其相关联的密封元件（20,21）处于延伸位置，并且用于在主排气口（13'，14'）处密封，同时活塞 4）距离其行程末端仍然相对较远。在进一步的冲程活塞（4）期间，空气因此可以仅通过辅助排气口（15'）排出，因此运动被缓冲。由于密封元件（27,28）采用延伸位置并且关闭主排气口（13,14），气缸排出的排气通过辅助排气港（15）。
