(54) | Lubricator device for grooved railway and tram rails |
(57) A line for grooved railway and tram rails (2) comprises grease dispensing means (8)
and grease spraying means (9) which can be connected to at least one through hole
(10) made through a part of a rail (2) delimiting the groove (7) and leading into
the groove (7), the dispensing means and the spraying means being designed in practice
to respectively dispense the grease on a surface of the rail (2) groove (7) which
is close to the through hole (10) and on a surface of the rail (2) groove (7) opposite
the through hole (10). First feed means (14) feed the grease to the dispensing means
(8) and to the spraying means (9), whilst second feed means (20) feed a pressurised
thrust fluid to the spraying means (9) for activating them. A control unit (27) is
operatively connected at least to the first feed means (14) and to the second feed
means (20), and is programmed for, in practice, feeding the grease to the dispensing
means (8) and to the spraying means (9), and for causing the grease to be dispensed
and sprayed respectively by the dispensing means (8) and the spraying means (9).
