摘要： Provided herein is a fluid duct 2 comprising a tubular base wall 11 surrounding a duct channel and at least one bellows 10 formed along a section of the tubular base wall 11. The bellows 10 comprises a plurality of convolutes 12 having a profile 14 projecting radially from the base wall 11. At least one convolute 12 wraps around the duct channel at a wrap-around angle Ω of between 180° and 720° from a first end 22a to a second end 22b of the convolute 12, said second end 22b being offset in a flow direction F parallel to a centerline C of the duct channel by a non-zero offset distance D from the first end 22a.

摘要： The present invention provides a corrugated tube and a method for manufacturing the same capable of improving workability in press-fitting work of a pipe or a quick connector. A corrugated tube includes a flexible section having a first corrugated section and a second corrugated section, and straight sections integrally formed at both ends of the flexible section respectively. A length of valley portions in an axial center direction is larger than a length of valley portions in the first corrugated section, thereby allows a pitch P2 of mountain portions in the second corrugated section provided between the straight section and the first corrugated section to be larger than a pitch P1 of mountain portions in the first corrugated section.

摘要： A fluid tube is disclosed herein. The breathing circuit tube has a wall which comprises a hollow geometry. The wall defines a passageway with a central longitudinal axis therethrough. The wall is expandable and contractible to adjust a diameter and a length of the passageway. The wall includes a partition and one or more corrugations that expand and contract to adjust the diameter and length of the passageway. The corrugations extend between terminal end portions of the wall.

摘要： A conduit made of a synthetic resin, having an inner surface and an outer surface, having concave portions and convex portions alternately and continuously provided in the length direction. The conduit is bendable. The conduit includes outer wall parts extending with a first width in the length direction; inner wall parts positioned radially inside relative to the outer wall parts and extending with a second width in the length direction; and side wall parts joining the outer wall parts and the inner wall parts so that the outer wall parts and the inner wall parts are alternately and continuously provided in the length direction. The outer surfaces of the outer wall parts each have, at both ends in the length direction, protruding parts, which protrude in the radial direction.

摘要： A four-layer-structured water passing device is provided, in which a first sleeve and a second sleeve are disposed between an elastic inner tube and an outer cloth sheath. When the water passing device is connected with a pressurized water source, the first sleeve can quickly eliminate or reduce the impact wave strength when receiving a strong expansion impact from the elastic inner tube, such that the first sleeve can gently transmit the fluctuation to the second sleeve, and the second sleeve extends the outer cloth sheath to the limit length, so as to avoid damage caused by frequent direct contact friction between the elastic inner tube and the outer cloth sheath. The water passing device is also configured to avoid permanent deformation and abrasion at the joint position between the elastic inner tube and the outer cloth sheath, and thus prolong the service life of the water passing device.
