摘要： In a control valve assembly for a pneumatically operated percussion device, a control valve piston is slidably mounted on a hollow release valve stem and encloses an auxiliary valve member to provide for automatic sequential operation. The admission of compressed air to the hollow release valve stem is blocked by a valve ring mounted on said valve stem, and the stem is provided with means for adjusting the rate of sequencing of the control valve piston and the auxiliary valve member.

摘要： A pneumatic stapler of the type having a working cylinder communicating with a surrounding air chamber by means of ports in the cylinder wall is provided with an annular valve means movable on the external surface of the cylinder wall. During the driving stroke of the piston said valve means closes the ports in the cylinder wall and opens an outlet passage for venting the air from the cylinder displaced by the piston and from the air chamber to the atmosphere. When the piston reaches the end of its driving stroke, said valve means opens the ports in the cylinder wall and connects the air chamber with a space beneath the piston and closes the outlet passage, whereby the piston is exposed to air pressure from the chamber for returning the piston to its initial position.
摘要翻译：具有通过气缸壁中的端口与周围空气室连通的工作缸的类型的气动订书机设置有可在气缸壁的外表面上移动的环形阀装置。在活塞的驱动行程期间，所述阀装置关闭气缸壁中的端口并且打开出口通道，用于将气体从气缸排出并且从空气室排放到大气中。当活塞到达其驱动冲程的末端时，所述阀装置打开气缸壁中的端口并将气室与活塞下方的空间连接并关闭出口通道，由此活塞暴露于来自腔室的空气压力将活塞返回到其初始位置。
