Abstract

Det er beskrevet en teleskoperende anordning som utgjør en del av en sugelednlng som igjen utgjør en del av et avsugsarrangement for avsuging av avfallsgasser eller andre miljømessig skadelige gasser fra minst et arbeidssted, hvor stigeledningen er forbundet med et sentralt avsugningsanlegg eller en vifte. Den teleskoperende anordningen innbefatter minst to rør (3, 4) som er bevegelig aksielt i forhold til hverandre, det vil si et ytre rør (3) og et indre rør (4) som utgjør sugeledningen (2) eller en del derav. Det indre røret (4) som er aksielt bevegelig l det ytre røret (3) er udnerstøttet av en glldelagerbøssing (7) som er montert ved den ytre enden (6) av det ytre røret og som har deler som er bevegelig i forhold til det ytre røret (3) og som kan bringes til forskjellig grad av Inngrep med det indre røret (4) for å kunne Justere frik- sjonskreftene som virker mellom bøsslngen (7) og det Indre røret (4).A telescoping device is disclosed which forms part of a suction line which in turn forms part of a suction arrangement for suction of waste gases or other environmentally harmful gases from at least one work place, where the ladder conduit is connected to a central suction system or fan. The telescoping device includes at least two tubes (3, 4) which are axially movable relative to each other, i.e., an outer tube (3) and an inner tube (4) constituting the suction line (2) or a portion thereof. The axially movable inner tube (4) of the outer tube (3) is supported by a ball bearing bushing (7) mounted at the outer end (6) of the outer tube and having portions movable relative to it. the outer tube (3) and which can be brought to varying degrees by engagement with the inner tube (4) to be able to adjust the frictional forces acting between the bush (7) and the inner tube (4).
