TL;DR: In this paper, the procedure for conducting static and dynamic tests required to evaluate gas-lift valve performance was outlined, and limited test results were presented for the 1- and 1 1/2-in (25.4- and 38.1-mm) unbalanced bellows-charged gas lift valves with three-ply monel bellows.
Abstract: Reliable predictions of injection gas passage through gas-lift valves are important for unloading and lifting high-capacity wells. This paper outlines the procedure for conducting static and dynamic tests required to evaluate gas-lift valve performance. Limited test results are presented for the 1- and 1 1/2-in (25.4- and 38.1-mm) unbalanced bellows-charged gas-lift valves with three-ply monel bellows.

TL;DR: In this article, an air spring has a flexible bellows between an upper-, movable support plate (30) and a lower mounting (44), and an inner-, concentric stop (38) is raised and lowered by an inner bellows (48) to enable the suspension to be lowered below normal levels.
Abstract: The air spring has a flexible bellows (26) between an upper-, movable support plate (30) and a lower mounting (44). An inner-, concentric stop (38) is raised and lowered by an inner bellows (48) to enable the suspension to be lowered below normal levels, (ie) by lowering the stop. The two air springs are separately controlled. The stop has a cylindrical support sleeve (66) which locates into a shaped recess (64) in the bottom of the system, centralising the lowered suspension. USE/ADVANTAGE - Air spring for heavy vehicle gives increased travel, improved loading access, reduced lateral movements.

TL;DR: A flexible vibration-damping joint where a metal bellows sleeve with undulations for rendering it elastically deformable is covered externally with a braided wire sheath and connected at opposite ends to respective rigid, tubular end pieces fittable to the pipe portions for connection is described in this paper.
Abstract: A flexible vibration-damping joint wherein a metal bellows sleeve with undulations for rendering it elastically deformable is covered externally with a braided wire sheath and connected at opposite ends to respective rigid, tubular end pieces fittable to the pipe portions for connection; and at least one annular vibration-damping pad made of compressed wire is inserted between the bellows sleeve and the braided wire sheath.

TL;DR: In this article, a deflatable sealing member forms a weatherstrip to seal a closure opening, and a flexible cable connects the sealing member to the closure or vehicle body to provide the necessary actuation for operation of the bellows pump in response to the swinging movement of the closure.
Abstract: A deflatable sealing member forms a weatherstrip to seal a closure opening. The sealing member includes an operative tubular section designed to provide tight interference engagement between the closure and vehicle body when vented to atmosphere and expanded by built-in resilient memory. A bellows pump is connected to the sealing member through a flow control circuit. The bellows pump serves to deflate the sealing member during closing of the closure. The bellows pump is adapted for convenient mounting in a cavity in the closure or vehicle body spaced from the closure hinge area. A flexible cable connects the bellows pump to the closure or vehicle body to provide the necessary actuation for operation of the bellows pump in response to the swinging movement of the closure. As the closure closes and latches, a valve is opened to vent the sealing member to ambient pressure, and the sealing member expands by resilient memory to its full cross section so as to provide a tight seal.

Journal ArticleDOI
TL;DR: In this article, the buckling of axially compressed bellows (axial force, internal pressure) in the presence of prebuckling nonlinearities is investigated, where the geometrical limitation of large elastic deflections of the bellows is taken into account.
