    • A gas spring with a piston reciprocable in a chamber of a casing, a sealing assembly at the rear end of the casing through which the piston rod extends, and an end cap closing the rear end of the casing. The sealing assembly has a reinforcing ring having a sealing ring on one side and a wiper on the other side. The sealing ring and wiper are portions of a single body of elastomeric material molded to the reinforcing ring and integrally connected through one or more openings in the reinforcing ring. The casing wall is rolled radially inwardly over the sealing assembly into pressure contact with the reinforcing ring so that the sealing assembly becomes in effect an end cap for the front end of the casing. The rear end of the casing is rolled over the rear end cap by swaging into pressure contact with the end cap. A filler valve is disposed in the end cap. In use, the piston is normally retained on the rod by an enlargement having a diameter larger than the bore of the rod bearing so that in the unlikely event the piston separates from the rod the enlargement will be embedded in the bearing to retain the rod in the casing. If the piston separates from the rod a port in the rod vents to the atmosphere the compressed gas in the chamber.
    • 一种气体弹簧,其具有可在壳体的腔室中往复运动的活塞,在壳体的后端处的活塞杆延伸穿过的密封组件和封闭壳体后端的端盖。 密封组件具有一侧的密封环和另一侧的刮水器的加强环。 密封圈和擦拭器是模制到加强环的单个弹性材料体的部分,并且通过加强环中的一个或多个开口整体连接。 壳体壁在密封组件上径向向内滚动,与加强环压力接触,使得密封组件实际上成为壳体前端的端盖。 套管的后端通过与端盖压力接触而在后端盖上滚动。 一个加注阀设置在端盖中。 在使用中,活塞通常通过直径大于杆轴承孔的尺寸保持在杆上,使得活塞在极小的情况下与杆分离,扩大将被嵌入到轴承中以将杆保持在 套管。 如果活塞与杆分离,则杆中的一个端口将空气中的压缩气体排放到大气中。

    • A gas spring with a piston (34) reciprocable in a chamber (14) of a casing (16), a sealing assembly (18) at the front end of the casing through which the piston rod (20) extends, and an end cap (22) closing the rear end of the casing. The sealing assembly (18) has a reinforcing ring (44) having a sealing ring (46) on one side and a wiper (48) on the other side. The sealing ring (46) and wiper (48) are portions of a single body of elastomeric material molded to the reinforcing ring (44) and integrally connected through one or more openings (54) in the reinforcing ring (44). The casing wall is rolled radially inwardly over the sealing assembly (18) into pressure contact with the reinforcing ring (44) so that the sealing assembly becomes in effect an end cap for the front end of the casing. The rear end of the casing is rolled over the rear end cap (22) by swaging into pressure contact with the end cap. A filler valve (96) is disposed in the end cap. In use, the piston (34) is normally retained on the rod (20) by an enlargement (32, 126) having a diameter larger than the bore of the rod bearing (36) so that in the unlikely event the piston separates from the rod the enlargement (32, 126) will be embedded in the bearing (36) to retain the rod in the casing.
