Yes that's it, a very clever design on an extremely thin stem of brass!

What does that cross hole actually do?
I assume that the coned tip has a seat at the bottom of the oiler to regulate the flow, or even shut it off, but I can't quite see what the cross hole in the shaft does to enhance function???
The stem is drilled right through from top to that cross drilled hole for easy refilling of oil.
That makes perfect sense, so that the stem doesn't have to be pulled out to add more oil, thus dumping all the oil into the machine.
Yep, should have figured that one out my-own-self!!!

@JinMachine
Jin that's some amazing machining, drilling through that tiny 1/16th thick brass stem on these beautiful oilers!!!!
