ISTALLAZIONE PER LA LUBRIFICAZIONE DI PORZIONI DI ROTAIE FERROVIARIE E SIMILI

An installation for lubrication of railway rails and the like, intended to be placed near the rail-track and including a control unit, a feed mechanism actuable by the control unit and at least one nozzle positioned adjacent either rail. The novel feature resides in that, in the feed mechanism which is actuable by means of the control unit (7) and comprises a pneumatically operated control system (6, 8) and a likewise pneumatically operated system (4, 5) for feeding lubricant from a supply tank (4) to the nozzle, the control system is divided into an actuating unit operable by means of the control unit (7) and working at low air pressure and an ejecting unit operable by means of the actuating unit (8) and working at high pressure, and the system for feeding lubricant includes a pump unit (5) driven at low pressure for feeding lubricant to the nozzle from which it is ejected at high pressure.
