(57) Abstract Objective As for oil supply nozzle of this device, tongue rail of railroadWith the oil supply nozzle which supplies the lube to the sleeve section of the floor face, the switching workThe industry is not done long haul when and, rise of outside air temperature such as summerSo, the lube starts neutron leakage even with when viscosity of the lube decreasesThere is no thing, only at the time of switching job the base and the deck boards of the tongue railOil supply nozu which can do to supply the lube which is necessary for the sleeve aspectIt is ru. Constitution Lightening friction drag to the tongue rail and the deck boards sleeve aspect,In order to do, the lube with the oil supply nozzle which refuels, the nozzle TipIn order for the ri lube neutron leakage, the oil neutron leakage prevention being full filler is internalized,It is the oil supply nozzle.
