Abstract
An arrangement for supplying consumers, particularly mobile consumers, with pressure fluids such as pressure air or pressure liquid, particularly in underground excavations, has a composite rail track for guiding a pressure fluid, a plurality of nipples arranged at a predetermined distance from one another in the longitudinal direction of the rail track, and at least one fluid withdrawing unit which cooperates with the nipples to open the latter and has a length selected with respect to the distance between two neighboring nipples so that one nipple is always located in the effective region of the withdrawing unit to be opened by the latter.
Claims11
An arrangement for supplying consumers, particularly mobile consumers, with pressure fluids such as pressure air or pressure liquid, preferably in undergound excavations, comprising a rail track arranged to guide a pressure fluid and having a longitudinal axis;
- a plurality of nipples arranged on said rail track at a plurality of locations spaced from one another by predetermined distances in a longitudinal direction of said rail track;
- at least one fluid withdrawing unit movable on said rail track and cooperating with said nipples so as to open the latter, said fluid withdrawing unit having a length which is selected with respect to the distance between two of said nipples so that one of said nipples is always located in the region of said withdrawing unit so as to provide automatic opening of said nipple;
- and a plurality of pairs of plungers each associated with a respective one of said nipples and each having two plungers which are spaced from one another in the longitudinal direction of the rail track, connected with one another in a scale balance-like manner, and extending beyond a periphery of said rail track, each of said plungers being formed to act on the respective one of said nipples so as to unlock the latter.
