Sleeve Patents (Class 285/145.4)
  • Patent number: 9599261
    Abstract: An adjustable joint having an outer housing section and an inner housing section telescopically disposed within the outer housing section. The inner housing section has an exterior portion within the outer housing section and which defines a circumferentially extending shoulder. An annular seal is positioned on the shoulder to create a seal between the outer housing section and the inner housing section. A circumferentially extending heat insulating spacer is attached to the shoulder and abuts the seal to retain the seal in place. A circumferentially extending heat shield is rigidly connected to the shoulder and abuts the heat insulating spacer and is located such that the heat insulating spacer is positioned between the heat shield and the annular seal.

  • Publication number: 20150137508
    Abstract: A sleeve for sealing an annular gap between opposed co-axial surfaces of a slip joint includes a tubular body formed from a metallic material and having a first end, a second end, a center section between the first and second ends, and a longitudinal cross-sectional profile having a plurality of bendable curves. The sleeve is shaped so that two or more of the bendable curves contact each opposed coaxial surface to form two or more circumferential lines of contact with each opposed coaxial surface. The sleeve further includes a self-protective oxide undercoat layer that protects the metallic material and a lubricous overcoat layer that provides lubricity to the contact surfaces when the sleeve is exposed to temperatures greater than about 600° C.

  • Patent number: 8480133
    Abstract: Provided is an apparatus for connecting two sub-flow systems (e.g. airplane fuel tanks) and conveying a fluid between the two sub-systems using a pressured balanced transfer tube, particularly when there are large radial and axial movements or offsets between the sub-systems. Unlike conventional fluid transfer systems, the present apparatus allows for the pressure in the transfer tube to be balanced to internalize the pressure forces and prevent the exertion of pressure forces on the sub-systems connected to the transfer tube.

  • Patent number: 8220839
    Abstract: A pipe insert providing a connection between pipe ends allowing fluid flow access between the pipe ends. The pipe insert having a central section with an internal thread that extends along the length of the central section and outer sections having inner and outer threaded ends. The inner threads allow attaching of the outer section into the central section so that the pipe insert may vary the relative displacement between the free ends of the pipe insert to correspond to the spacing between the pipe ends. The outer threaded ends having a releasably attaching connection to the outer section to provide a connection between the spaced pipe ends. The pipe insert is particularly useful during replacement of an appliance located between the pipe ends. The pipe insert is adapted to receive flow control and/or sensing element for measurement of fluid flow between the pipe ends.

  • Patent number: 7451785
    Abstract: A flexible tube 10 of the present invention is disposed downstream of a exhaust path from an engine E, and formed of an outer bellows 3 as an outer tube and an inner bellows 4 as an inner tube; pleats 4c,4c of the inner bellows 4 are smaller in depth and pitch than the pleats 3c of the outer bellows 3, and the buffering space S is provided with a gap t between the pleats bottoms of the outer bellows 3 and the pleats tops of the inner bellows 4, and further, a partition 17 that splits the exhaust path is disposed in the inner bellows 4. For this reason, sound insulation effect is improved, and the lowering of the temperature of the exhaust gas is suppressed, leading to quick temperature rise of the exhaust gas to be fed into the catalytic converter, thereby promoting the activation of the catalysts and improving the capability to purify exhaust gas, and the exhaust efficiency can be improved thereby increasing output performance of the engine.
