Abstract: This female element of a quick connector that connects to a male element and has a hollow body, which extends along an insertion axis and which delimits a receiving volume for the male element. Radial openings, formed in the body along a radial axis, open into the receiving volume. Each radial opening receives a latch, translatable in relation to the body along the corresponding radial axis, between a locked and an unlocked position. The female element has an actuating ring arranged about the body and translatable between a locked and an unlocked position. The ring has guide grooves, which interact with pins of each latch. The guide grooves associated with each latch are geometrically carried by a guide plane inclined in relation to the insertion axis so that each latch is driven between its locked and unlocked positions when the actuating ring is moved between its locked and unlocked positions.

Abstract: Each of a pair of couplers includes: a vacuum double-pipe structure main part; a valve seat forming an opening through which a fluid flows; and a valve body in the main part. The valve body is configured such that, when separating the couplers, in each coupler, the body is brought into contact with the seat by a spring to close the opening, and when coupling the couplers, the body of each coupler is pressed by the body of the other coupler to move away from the seat and open the opening. The valve body includes: a holding member holding a sealing material sealing between the body and the seat when the body is in contact with the seat; a resin block covering a distal end surface of the holding member; and a metal operating member accommodating the block and protruding from the holding member to pass through the opening.

Abstract: A device for gas-tight connection includes: a first connection point with a terminal surface; a second connection point with a stationary, predetermined reference surface of a pipe flange connection, which is arranged relative to the terminal surface by an offset angle which is compensated for by an angular offset compensation; and a flanged disc unit. The first connection point includes a central ball-and-socket joint arrangement as an angular misalignment compensation. The central ball-and-socket joint arrangement has a tube section with a convex distal end region configured to interact in an articulated manner with a concave annular region, corresponding thereto, of the flanged disc unit. A side surface region of the flanged disc unit includes at least one adjusting screw for adapting to the offset angle so as to adjust a local distance to a counter-disc fixedly fastened coaxially to a pipe section adjacent to the convex distal end region.

Abstract: A plug-in coupling for connecting a first to a second double-walled, vacuum-insulated cryogenic line includes a coupling plug and a coupling socket. The coupling plug has an inner and an outer pipe piece and a first connecting flange and is connected to the first cryogenic line. The coupling socket has an inner and an outer pipe piece and a second connecting flange and is connected to the second cryogenic line. In an assembled state of the plug-in coupling, the coupling plug has been plugged into an open annular gap in the coupling socket. The annular gap is surrounded both at its inner circumference and at its outer circumference by an insulating vacuum, whereby the thermal insulation of the plug-in coupling is improved. This construction makes possible a shorter design of the plug-in coupling, which, while achieving good thermal insulation, is space-saving and easy to handle.

Abstract: A downpipe fitting for coupling between top and bottom ends of a downpipe. The downpipe fitting includes two parts connected together and rotatable relative to one another about a longitudinal axis thereof. The first part has an inlet, sized and shaped to couple with an outlet of a first section of the downpipe, above the downpipe fitting. The second part has an outlet which is sized and shaped to couple with an inlet of a second section of the downpipe, below the downpipe fitting. The inlet and outlet of the fitting define a flow path for rainwater therethrough. Rotation of the second section of downpipe below the downpipe fitting, about the longitudinal axis, is decoupled from the first section of downpipe above the downpipe fitting.
