Anyone know what this is? It is pretty substantial brass, seems like it has a venturi cone on the female end, the internal bore opening in the male end is larger than the female end.

If you hook it up to a hose, does water come out the holes on the side of the cylinder?

Maybe a jet siphon of sorts

Any numbers stamped on it?

Looks like part of an old gas light burner.

Looks like a siphon to me.
Connect one end to water supply.
Connect hose on other end.
Drop unit into pool and turn on water.
Siphon effect will suck water into the holes and blow it out the other end.

When I was on a volunteer fire department years ago we had a tool called a turbo Draft. It was a glorified jet siphon. If you needed to fill a tanker we would normally use a hard suction pipe. If the water supply was to far away for hard suction you could Turbo Draft. I believe it was 2:1 ratio, if you flowed 100gpm out you could fill at 200gpm.

It looks like an eductor that works on the Bernoulli principle. Wow, did that make me sound smart or full of sh—?

Looks like standard plumbing threads. Perhaps a type of vacuum break?

Interesting. I’ll have to connect it tomorrow and see what it does.
Assuming we’re talking about water,is the principal that if you want to fill something, you attach it at the source output, run the hose back so the siphon sits in the source water and the output consists of the normal flow through the hose plus what is sucked up by the device?

Your principles are correct but I suggest it is for emptying something not filling.
For example if your power was out you could hook this thing up and drain your sump pit.

The tiny hole through the middle would suggest this not a vacuum breaker.

 

[Georgepag]

Right. Rather than saying “fill”, transfer a liquid from one place to another would have been more accurate. Thanks for all the replies. I’ll let you know what happens tomorrow, if it isn’t too cold outside (New Hampshire).

Yea, like I said, the Bernoulli principle.

I had to look it up so you must have sounded smart.
