Facts worth knowing about Oil nozzles - Danfoss.com

How does a Danfoss oil nozzle work?To find the answer to this question it is necessary first to take a close lookat how the oil travels through the small slots in the nozzle.Oil enters through the filter and continues through the bottom screw and itsside holes. From there, the oil runs along the side of the cone and into thecone slots.When the oil, under high pressure, is forced through the cone slots it entersthe swirl chamber. On its way through the cone slots some of the oilpressure is converted into rotational energy.In the swirl chamber, the oil gains strong rotary motion and a rotating oilfilm is formed which moves towards the nozzle orifice.The velocity of the oil film is so great that a “tube” of oil is formed in thenozzle orifice. With the help of that part of the pressure not converted intorotational energy this “oil tube” is forced through the nozzle orifice. On beingpropelled from the orifice, the “oil tube” is expanded so much that itbreaks up into very small oil drops.7
