摘要： The present invention provides a flexible hose for connecting a fuel manifold to a burner of a gas turbine engine. The flexible hose includes a metal convolute tube, an elongate member or members located in grooves formed in the inner surface of the convolute tube, and a pressure-containing sheath outside the convolute tube. The flexible tube has end connectors fluidly-tightly joined to respective ends of the hose for connection at one end of the hose to the fuel manifold of the gas turbine engine, and at the other end of the hose to the burner of the gas turbine engine.

摘要： An outlet tube includes a first rib, a second rib, and a channel positioned between the first rib and the second rib. The first rib extends from a surface of the tube. The first rib tapers between a first thickness and a second thickness. The second rib extends from the surface of the tube. The second rib tapers between the first thickness and the second thickness. The channel has a first width between adjacent first thicknesses and a second width between adjacent second thicknesses. The first width is greater than the second width.

摘要： Provided is a device for automatic refueling of a vehicle that includes a nozzle having a flexible filler pipe with an open end. The filler pipe is inserted, with the open end first, into the tank pipe to deliver fuel through the open end into the tank pipe. An axial pressure is applied to the filler pipe to insert the filler pipe into the tank pipe. The filler pipe includes an inner fuel pipe of flexible hard plastic material, and an outer metal coil or a series of metal rings. The metal coil or metal rings are arranged to run in parallel to and outside of the inner fuel pipe. The metal coil is arranged to run in and along a recess in the surface of the inner fuel pipe and the metal rings are disposed in a series of annular recesses in the surface of the fuel pipe.

摘要： A fluid line having a wave form portion is furnished. The wave form portion extends at least at a minimum distance along a longitudinal axis of the fluid line. The wave form portion has a wave peak element (18), which itself has, along a peripheral direction extending around the longitudinal axis of the fluid line, a varying distance from the longitudinal axis, the distance including a distance curve in the peripheral direction, the distance curve providing a non-circular contour. A fluid line is thus provided having a wave form portion, which fluid line reduces the pressure drop at the wave form portion.

摘要： A corrugated tube with a plurality of wave valleys and wave crests, which are alternately arranged in a longitudinal direction of the corrugated tube, and a plurality of wave flanks, which connect the wave valleys and the wave crests to each other, wherein each wave flank comprises a first wave flank section, a second wave flank section, and a bending section arranged between the first wave flank section and the second wave flank section, and wherein the bending section is elastically deformed during bending of the corrugated tube such that the first wave flank section is swiveled in relation to the second wave flank section.

摘要： A corrugated tube that can be folded open, for holding cables, comprises: first and second corrugated tube shells, which have a respective plurality of first and second corrugated tube ribs extending peripherally around the respective corrugated tube shell, a joint section, which separates the corrugated tube ribs from each other and pivotably connects the corrugated tube shells to each other, at least one lip section, which is provided on at least one of the corrugated tube shells, and a locking device for locking the two corrugated tube shells to each other when the corrugated tube is brought from a folded-open state into a folded-together state. The locking device includes the corrugated tube ribs, and in the folded-together state, the second corrugated tube ribs extend around the first corrugated tube ribs interlockingly both in a radial direction and in a peripheral direction of the corrugated tube.

摘要： One aspect of the invention provides an elastomeric bushing including: a plurality of rigid members defining one or more internal annular ribs and one or more elastic members. The rigid members include: a first internal annular rib adapted and configured to engage a corrugation valley of corrugated tubing; and one or more trailing lips adapted and configured to extend through a central opening of a nut and engage said nut, thereby preventing axial movement of the bushing when a corrugated tubing is advancing through the bushing. The one or more elastic members are adapted and configured to: hold the plurality of rigid members in a substantially annular configuration; allow the plurality of rigid members to expand to allow a corrugation peak to pass under the first internal rib; and hold the plurality of rigid members against the corrugated tubing so that the first internal rib lies within a corrugation valley.

摘要： A plastic drain pipe for drainage includes a first end, a second end, and a pipe sub-section between the first end and the second end. The pipe sub-section includes a collapsible section of corrugated pipe, a first non-collapsible section of corrugated pipe, and a second non-collapsible section of corrugated pipe. The collapsible section of corrugated pipe has a first joining area and a second joining area. The first non-collapsible section of corrugated pipe is connected to the collapsible section of corrugated pipe at the first joining area, and the second non-collapsible section of corrugated pipe is connected to the collapsible section of corrugated pipe at the second joining area.
