Title (EN) INSTALLATION FOR PORTIONAL LUBRICATION OF RAILWAY RAILS AND THE LIKE
(FR) DISPOSITIF DE LUBRIFICATION DE RAILS DE CHEMIN DE FER ET AUTRES
Abstract: front page image
(EN)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.
(FR)Dispositif de lubrification de rails de chemin de fer et autres, destine a etre place a proximite d"une voie de chemin de fer et comprenant une unite de commande, un mecanisme d"alimentation actionne par l"unite de commande et au moins un ajutage adjacent a chaque rail. La caracteristique nouvelle reside en ce que, dans le mecanisme d"alimentation, actionne au moyen de l"unite de commande (7) et comprenant un systeme de commande pneumatique (6, 8) et un systeme pneumatique similaire (4, 5) d"alimentation en lubrifiant d"un reservoir d"approvisionnement (4) vers l"ajutage, le systeme de commande comprend d"une part un dispositif de manoeuvre commande par l"unite de commande (7) et fonctionnant a faible pression d"air, et d"autre part un ejecteur qui est commande par le dispositif de manoeuvre (8) et qui, lui, fonctionne a haute pression; le systeme d"alimentation en lubrifiant comprend une pompe (5) a basse pression pour alimenter en lubrifiant l"ajutage, d"ou il sort sous haute pression.
