ATOMIZING NOZZLE FOR DELIVERING LUBRICANT TO WHEEL FLANGE Russian patent published in 2006 - IPC B61K3/00 

FIELD: railway transport; lubricant of vehicle wheel flanges.

SUBSTANCE: proposed nozzle has housing with air channel, taper tip with cylindrical space mating with conical space in apex of which hole is made to let out lubricant, and atomizer with central stepped axial channel mounted inside housing and tip. Atomizer is provided with needle valve with spring and sealing ring on end. Atomizer is made in form of stepped cylinder with outer thread to turn into housing and it is installed coaxially with tip on outer surface of which thread is cut, engaging with thread on inner axial channel of housing. Valve is made with bead which can thrust against step of atomizer channel. Clearance between bead of valve and step of atomizer channel is less than clearance between conical surface of needle valve and inner conical surface of taper tip measured along axis of valve. Clearance is found between inner surfaces of taper tip and outer surfaces of Atomizer, sealing ring and valve. Outer thread is cut on end of atomizer brought out of housing and channel is made with inner cone for connecting oil line.

EFFECT: improved reliability of atomizing nozzle, reduced labor input in manufacture, and simplified design.
