Universal connector hose for joining an extractor to an element for extracting fumes from a factory workplace |
摘要 |
The hose comprises two flexible portions connected respectively to the suction unit and to the fume-conveyor element or hood, and a rectilinear portion which is articulated to the suction unit and the hood. The rectilinear portion comprises two rigid tubes between which is disposed an extensible bellows-type tube. Rigid tubes are held co-axial by a pair of rectilinear guides fixed to one of the rigid tubes and slidably engaging on a pair of fixed slides on the other rigid tube. The two rigid tubes are, finally, connected by a tension spring the action of which is braked by two friction disks disposed between the guides and the slides.
