Air spring leg with telescopic component formed as shock absorber

Abstract: The telescopic component has a cylinder in which is inserted a piston and combined with is a variable vol. air chamber, which is enclosed by a first housing part with spinning movement and connected to the piston, a second housing part held on the cylinder, and a bellows arranged between the two housing parts. The cylinder-side housing part (3) with its end remote from the bellows is arranged with spinning movement on the cylinder of the telescopic component (4). On the cover of the cylinder of the telescopic component a flange-type collar (6) is arranged, which via a ring part (5) of elastomer material is connected with spinning movement to a flange-type ring are on the cylinder-side housing part.

Pedestal mounted full reservoir air spring piston

Abstract: An air spring has a piston formed of a high strength plastic material consisting of a main shell and a bottom end sealing plate extending between a pair of concentric inner and outer annular walls. A pair of internal auxiliary reservoirs or subchambers are formed within the piston and are in fluid communication with each other and with the main air chamber formed by a flexible bellows extending between the piston and an end plate. A plurality of radially extending reinforcing ribs extend between the inner and outer annular walls of the shell and a rigid central post. A central planar support surface having an area approximately 20% than that of the piston base area provides a reduced surface area for mounting the piston on a smaller support surface.

Fan coil unit

Abstract: A fan coil unit includes a coil supported above a primary pan defining therebetween a gap which is closed by a thin flexible water impermeable bellows which prevents air from a fan from being blown through the gap and instead directs the air through the coil. The primary pan is in situ molded with rods therein for reinforcement and also includes upstanding motor mounts which prevent faster corrosion.

Gas lift valve

Abstract: A gas lift valve that is usable with a subterranean well includes a housing, a valve stem and at least one bellows. The housing has a port that is in communication with a first fluid, and the valve stem is responsive to the first fluid to establish a predefined threshold to open the valve. The bellow(s) form a seal between the valve stem and the housing. The bellow(s) are subject to a force that is exerted by the first fluid; and a second fluid contained in the bellow(s) opposes the force that is exerted by the first fluid.

Heat pipe with axial and lateral flexibility

Abstract: A flexible heat pipe is disclosed for use with evaporator and condenser elements for removing heat from electronic components. The flexible heat pipe comprises a bellows member fixed at one end to a condenser member and at an opposite end to an evaporator member. A cable artery is disposed within the bellows and is fixed at one end to the evaporator, and slidingly engages the condenser at the opposite end. The bellows acts as a flexible vapor envelope, and the cable artery acts as a flexible wick for directing condensed working fluid from the condenser back to the evaporator. The sliding connection between the cable artery and the condenser allows relative axial movement, and the inherent flexibility of the cable artery allows relative lateral movement. Thus, the condenser and evaporator can move in all directions with respect to each other, which can provide desired vibration isolation of the two components.
