A hose arrangement includes an outer tube of flexible material and an inner tube of an elastic material for carrying fluid. Due to an action of the elastic inner tube, the hose has a shorter length in a contracted state in the absence of fluid pressure in the interior of the inner elastic tube and a longer length in an expanded state when the fluid pressure is applied to the interior of the elastic inner tube. The tube has an undulating state in the contracted state and controls and contains expansion of the inner tube when the hose is in the expanded state. At least one sleeve portion is provided between the elastic inner tube and the outer tube along a part of the elastic inner tube where undulation of the outer tube occurs in the contracted state for protecting the elastic inner tube from abrasion undulations of the outer tube.

Aspects of this disclosure can be used to implement a braided cover comprising a plurality of left handed fibers and a plurality of right-handed fibers braided into a hollow tube of fabric. Such a braided cover may be adapted to form a plurality of annular ridges and annular valleys along the longitudinal length of the braided cover when compressed from an extended length to a compressed length.

The present invention relates to a thermoplastic hose, consisting of a flexible hose body (12; 212; 312; 612) and at least one reinforcing element (14; 214; 314; 614), which is arranged helically on the external face of the hose body (12; 212; 312; 612), wherein the at least one reinforcing element (14; 214; 314; 614) is made of an extruded material and is rigidly joined to the external face of the hose body (12; 212; 312; 612) by means of a fusion bond, wherein the hose body (12; 212; 312; 612) is an extruded hose body (12; 212; 312; 612). The invention also relates to a device and a method for producing such a hose.

A tubing apparatus includes corrugated tubing including convolutions of peaks and valleys in the body of the tubing; an electrically conductive or semi-conductive, polymer jacket disposed along an exterior length of the corrugated tubing; wherein the jacket provides protection to the inner corrugated tubing from damage resulting from electrical arcing at levels ranging from at least 9 coulombs at a waveform of 10 microseconds×1000 microseconds.

An elastic tubular body includes a grommet fitted to an opening edge of a mounting hole of a support body, a flared portion formed in a flare shape and deformable so as to invert an inner face and an outer face and having a large diameter edge coupled to the grommet; and a bellows-like tube of a bellows-like tubular shape having a smaller diameter than an inner diameter of a small diameter edge of the flared portion, a first end of the bellows-like tube connected with the small diameter edge of the flared portion. The flared portion is configured to be in a state projecting from the grommet or in a state where the outer face is reversed to enter inside the inner face and store the flared portion in a storage space of the grommet. The bellows-like tube is stored inside the flared portion stored in the storage space.

Provided is a hose including a first connector assembly including a regulator assembly, a second connector assembly, and a hose assembly coupled to the first and second connector assemblies. The hose assembly includes an inner hose member having first and second ends, an outer hose member having first and second ends, a first hose connector assembly coupled to the first ends of the inner hose member and outer hose member and the first connector assembly, and a second hose connector assembly coupled to the second ends of the inner hose member and outer hose member and the second connector assembly.

This invention provides for a component forming a part of a breathing tube, or forming the breathing tube, for example as a part of a breathing circuit for respiratory therapy. The component comprising a tubular body having a foamed wall. The foamed wall can be formed from extrusion of a single extrudate. The foamed wall is of a sufficient minimum optical transparency such that, in use, there is enabled the visual detection of a liquid (or condensate that may have formed) within the tubular body.

A magnetically positioned dryer vent coupling is adapted for use in combination with a clothes dryer. The dryer vent coupling includes a flexible exhaust duct, a first mounting substrate, and a second mounting substrate. The first mounting substrate is located at one end of the flexible exhaust duct and includes a first magnet. The second mounting substrate is adapted for residing proximate one of the dryer exhaust port and wall port, and includes a second magnet. When moved into close proximity, the first and second magnets magnetically attract to one another to self-align and self-assemble the first and second mounting substrates of the dryer vent coupling, such that the first and second mounting substrates create an audible snapping sound when engaged thereby indicating a close magnetic seal at the dryer vent coupling.
