摘要： The invention relates to a plug-in connection, for example for producing liquid-tight or gas-tight connections in the automobile industry, between a connecting piece (18) and a plug-in part (14) that can be connected thereto. Said connecting piece and plug-in part can be plugged into each other and locked together. The inventive plug-in connection comprises a moulded sealing ring (1) containing a base body (2) with a relatively large cross-section, to which an radially and/or axially elastic spring leg (9) with a smaller cross-section is radially applied. The base body (2) is received in a sealing groove (21) of the first part (14, 18), and the spring leg (9) is applied to a radial surface (31) on the other part (18, 14) in a sealing manner. A sealed lead (10) with a larger cross-section than that of the spring leg (9) is embodied on the front free end of the spring leg (9). Advantageously, the moulded sealing ring (1) acts as a superpressure seal, but also as an underpressure seal in the event of very small plug-in forces, and is cost-effective and simple to mount.

摘要： A subsea telescoping joint 12 having an outer tubular member 34, and an inner tubular member 32, an internal serrated locking and metal-to-metal sealing surface 42 within said outer tubular member, an external serrated locking and metal-to-metal sealing surface 60 on the exterior of said inner tubular member, means 48 sealing between the tubular members to provide a pair of fluid chambers between the members, means for supplying pressure fluid to said chambers, the locking and sealing surfaces having a slight interference fit which allows relative movement of the members with the presence of fluid pressure in said chambers and on relieving of such fluid pressure from said chambers the surfaces move into locking and metal-to-metal sealing engagement with each other. In one form of the invention the sealing means are at the same diameter so that there is no pressure force developed tending to extend or retract the joint and in another form the sealing means are at different diameters so that a force is developed responsive to the fluid pressure tending to extend the telescoping joint.
