摘要： A pusher which has a stroke shorter than that of a piston at either position on a head side or a rod side in a cylinder main body and which serves as both means for pushing the piston from a stroke end back to an intermediate stopping position and means for stopping the piston at the intermediate stopping position is disposed so as to be movable independently from the piston, and pressing means for causing the pusher to displace to the intermediate stopping position is provided.

摘要： The invention concerns an hydraulically powered mechanism of the kind having a piston assembly which is arranged to be driven by hydraulic fluid acting on it in a working zone and an item of equipment which is to be driven by the piston assembly. The piston assembly presents a face which acts at an interface against a complemental face on the item of equipment. A fluid passage is provided to supply hydraulic fluid from the working zone to the interface for lubrication purposes. In a specific application of the invention it may be used in the rotary indexing mechanism of an hydraulically powered, typically a water-powered, rockdrill.

摘要： An inner seal band having flat surfaces on both sides is used for closing a slit formed on the cylinder tube of a rodless cylinder. An internal moving body is disposed in the cylinder tube and moves along the longitudinal axis of the cylinder tube. The inner seal band passes through a channel groove formed on the bottom face of the internal moving body. Thin plate-like abrasion members made of synthetic resin are adhered on the side walls of the channel groove. The abrasion members contact with the edges of the inner seal band and restricts its movement in the transverse direction. Since the abrasion members are separate members from the side walls of the channel groove, a material different from that of the side walls, such as abrasion resistant material can be used for the guide members. Further, the thickness of the guide members can be selected in accordance with the actual width of the channel groove and the difference in the width of the channel groove due to machining tolerance can be compensated for by using the guide members having appropriate thicknesses.
摘要翻译：使用两侧具有平坦表面的内密封带封闭形成在无杆缸的气缸筒上的狭缝。内部移动体设置在气缸筒中并沿着气缸管的纵向轴线移动。内密封带穿过形成在内部移动体的底面上的通道槽。由合成树脂制成的薄板状磨损构件粘附在槽槽的侧壁上。磨损构件与内密封带的边缘接触并限制其在横向上的运动。由于磨擦构件与通道槽的侧壁是分离的构件，因此可以使用与侧壁不同的材料，例如耐磨材料。此外，可以根据通道槽的实际宽度来选择引导构件的厚度，并且可以通过使用具有适当厚度的引导构件来补偿由于加工公差导致的沟槽的宽度差。
