摘要:
The present invention describes a flexible conduit element with an end portion suitable for attachment to a rigid conduit element. The flexible conduit element comprises: a bellows member; an interlock member; an outer fixing member; and an connection nozzle, where, in an axial cross section at an end portion of the flexible conduit element, the outer fixing member is disposed outside of the bellows member, the bellows member is disposed outside of the interlock member, and the interlock member is disposed outside of the connection nozzle, and a gas-tight seal connects the bellows member and the connection nozzle. A method of assembly such a flexible conduit element is also disclosed.

The invention relates to line elements (600) consisting of a multi-layer inner element (IE) and an outer element (AE), wherein the inner element (IE) and the outer element (AE) are in contact with each other at points, at lines, over part of the surfaces thereof, or over the full surfaces thereof. Furthermore, a frictional contact protection means extending over the component length is provided, or a frictional layer (121) is provided in the contact region of the inner element (IE) and the outer element (AE). The wear of the outer element (AE) caused by friction can thereby be minimized.

A flexible conduit system having a corrugated flexible conduit, a first tapered member disposed in the flexible conduit at the inlet end or close to the inlet end of the corrugated flexible conduit and a second tapered member disposed in the flexible conduit at the outlet end or close to the outlet end of the corrugated flexible conduit. The first tapered member at the inlet end converges and centers the flow of gases through the flexible conduit and the second tapered member at the outlet end channels the flow of gases away from the corrugations of the corrugated flexible conduit thereby reducing noise in the flexible conduit system.
摘要:
A pipe joint structure for an exhaust gas treatment device for an industrial vehicle that can absorb an external force and that can facilitate a fine adjustment of a gap formed at the pipe joint part for introducing the outside air into the pipe joint part. A diesel particulate filter (or an exhaust gas treatment device) 1 is provided with an exhaust pipe 5. A tapered distal end portion 5a of the exhaust pipe 5 is inserted into an opening portion 4a of the tail pipe 4 and a gap is formed of a tapered cross sectional shape between the distal end portion 5a of the exhaust pipe 5 and the opening portion 4a of the tail pipe 4. The exhaust pipe 5 has first bracket members 11, 11′ and the tail pipe 4 has a second bracket member 12. Attachment bolts 13, 13′ are inserted through the first bracket members 11, 11′ and the second bracket member 12. Coil springs 15, 15′ are fitted around the outer peripheries of the attachment bolts 13, 13′ between the first bracket members 11, 11′ and the second bracket member 12. The distal end portion 5a of the exhaust pipe 5 is elastically supported relative to the opening portion 4a of the tail pipe 4 in the longitudinal direction of the pipe.

In a cylindrical gasket 23, a heat-resistant material 1 made from expanded graphite and a reinforcing member 2 made from a metal wire net are provided with structural integrity by being compressed and intertwined with each other. A cylindrical inner peripheral surface 19, a cylindrical outer peripheral surface 20, and axial annular end faces 21 and 22 which are exposed on the cylindrical gasket 23 are each formed by a surface where a surface constituted of the heat-resistant material 1 and a surface constituted of the reinforcing member 2 are present in mixed form, and in the cylindrical gasket 23, the density of the heat-resistant material 1 is in the range of 1.21 to 1.58 Mg/m3, and the mass of the reinforcing member 2 occupies 50 to 80% of the total mass of the cylindrical gasket 23.

摘要:
For connection of pipelines which are subject to vibration, for example pipelines in vehicle exhaust systems, a liquid-tight decoupling element is used which includes a, e.g. multi-layer wound, metal hose and a tube accommodated in coaxial relationship inside or outside of the metal hose. A first axial fitting firmly secures one end of the tube. The tube is sized to protrude into a second axial fitting, regardless whether the metal hose is completely compressed or completely stretched, to allow movement of the tube in axial and torsional directions in relation to the second axial fitting.

A flexible exhaust stack is suitable for use with a vehicle for which relative motion occurs between the cab of the vehicle and exhaust system components mounted to the vehicle frame. The exhaust stack includes a pipe mounted to the cab and having inlet and discharge ends. A collar is secured to an interior portion of the pipe between the inlet end and the discharge end. A flexible hose is at least partially disposed within the pipe, with a discharge end secured to the collar and an inlet end in fluid communication with the frame-mounted exhaust system components. The exhaust stack receives exhaust gases from the frame-mounted exhaust system components and discharges the exhaust gases from the discharge end of the pipe, while the flexible hose allows for relative motion between the cab and the exhaust system.
