摘要： A concentric slave cylinder having a housing (10) with radially spaced inner (11) and outer (12) walls defining an annular working chamber (13) therebetween in which an annular piston (14) is axially slideable. Seals (23, 24) are provided between the piston (14) and the inner and outer walls (11, 12) to seal the working chamber. These seals comprise a first seal (24) housed in an annular recess in the outer wall (12) which contacts an outer surface of the piston (14) and a second seal (23) housed in an annular recess in the inner wall (11) and which contacts an inner surface of the piston (14).

摘要： A method of connecting a hydraulic component (21) to a plastics hydraulic pipe (12a, 12b) by forming the component from a harder material than the pipe with an internally screwed bore (25) for reception of the pipe, the screw thread (26) formed in the bore being of a tapering form with the internal diameter of the bore decreasing with distance from the open end of bore, and screwing the component (21) onto the pipe (12a, 12b) with the component forming a complementary thread on the outside of the pipe as the component is screwed on. The method is particularly suitable for connecting a component such as a pipe end fitting, a pipe connector, a valve housing, a cylinder body or a damper casing formed from glass reinforced plastic or metal with a pipe formed from plastics material.
摘要翻译：将液压部件（21）连接到塑料液压管（12a，12b）上的方法，该方法通过用具有用于接收管子的内螺纹孔（25）形成来自具有比管更硬的材料的部件，螺纹（26 ）形成在所述孔中的锥形形状，所述孔的内径随着距离孔的开口端的距离而减小，并且将所述部件（21）旋拧到所述管（12a，12b）上，所述部件形成互补螺纹作为组件的管的外部被拧紧。该方法特别适用于将由玻璃钢或金属形成的管端配件，管连接器，阀壳体，气缸体或阻尼器壳体等部件与由塑料材料形成的管连接。

摘要： An annular seal (39) for use in a hydraulic cylinder in which a piston (12) moves along a bore (13) in a cylinder body defining a hydraulic working chamber (16) ahead of the piston, the seal having a forward lip portion (40) exposed to the hydraulic pressure in the working chamber which seals the working chamber against egress of fluid from the working chamber around the piston, and a rearward lobe portion (41) which has a rear face which seats against a support surface (12a) on the piston or body, the lobe portion sealing against the ingress of air or other contaminants around the piston into the working chamber. In the unpressurised condition, in the vicinity of the lobe portion the rear face (42) of the seal (39) slopes (9) away from the support face (12a) towards the working chamber (16) so that when the seal is pressurised the rear face is not forced past the support surface into the clearance (x) between the piston (12) and bore (13). The seal (39, 52) may be of the twin lip and lobe type used to seal an annular piston to inner and outer walls of an annular bore or to seal a cylindrical piston within a cylindrical bore or of the single lip and lobe type (52, 58, 59) in which the seal is held captive in the walls of an annular or cylindrical bore to seal against a moving annular or cylindrical piston or is held in a recess in a moving piston for sealing with a mating bore.
摘要翻译：一种在液压缸中使用的环形密封件（39），其中活塞（12）沿着限定了活塞前方的液压工作室（16）的缸体中的孔（13）移动，所述密封件具有前唇部分（40），其暴露于工作室中的液压压力，其密封工作室，防止流体从活塞周围的工作室流出;以及后凸起部分（41），其后表面抵靠支撑表面（12a ）在活塞或主体上，凸起部分密封住活塞周围的空气或其它污染物进入工作室。在非加压状态下，在凸起部分附近，密封件39的后表面42朝着工作室16离开支撑面12a而使斜面9从密封件加压后表面不被迫通过支撑表面进入活塞（12）和孔（13）之间的间隙（x）中。密封件（39,52）可以是用于将环形活塞密封到环形孔的内壁和外壁的双唇和凸角型，或者将圆柱形活塞密封在圆柱形孔内或单唇和叶型（ 52,58,59），其中密封件被保持在环形或圆柱形孔的壁中以密封移动的环形或圆柱形活塞，或者保持在活动活塞中的凹部中以与配合孔密封。
