Abstract

Dans cet ensemble télescopique pneumatique du type comprenant une chambre de charge 24 adaptée pour être remplie d'un gaz sous pression, un piston 15 mobile sous l'action de la pression du gaz et des moyens pour régler le volume maximal du gaz se trouvant dans la chambre de charge, lesdits moyens pour régler ledit volume sont constitués par une certaine quantité d'un corps solide 38. Application à la tension des câbles d'alimentation caténaires pour véhicules ferroviaires à traction électrique.In this pneumatic telescopic assembly of the type comprising a load chamber 24 adapted to be filled with a pressurized gas, a piston 15 movable under the action of the gas pressure and means for adjusting the maximum volume of the gas in the gas pressure. the charging chamber, said means for adjusting said volume consist of a certain amount of a solid body 38. Application to the tension of catenary power cables for electric traction railway vehicles.
