Identify the [Heart] Mini Widget

[DaveC426913]

My boy brought this thing home for me to identify.

I am 95% certain it's a water filter, but it can't possibly function as one. And it doesn't make sense as one.

It's labeled [heart] Mini.
The attachment is garden hose thread.
The dial goes 0, *, 1, 2, 3, 4, 5 (The asterisk could be a snowflake.)
The dial screws in and out, causing the white cylinder to move in and out.
Note the orientation of the numbers. The widget is meant to be mounted on top of something, (not underneath, like a sink faucet).
The inside has a black plastic cylinder, which could be a case for a filter.
It looks like water could come out those 20 or so holes on the bottom edge.
But here's the thing: any water that goes into it will just some pouring straight out the gaps in the hose "clamp".

Thank you. That's exactly what it is, although I still think there's a piece missing.

Comparing this with the pictures in the Wikipedia article Thermostatic radiator valve, it looks like you have the "thermostatic" part, but not the "valve" part.

Yeah I've no doubt there more to it, the problem I have is that I don't see how an extra part could mitigate the problem with this part. See the first pic in post #1. The teeth that are driven by the nut have great gaps between them, out of which any water will come gushing.

Now, everything I know about "thermostat heads" I've learned in the last 10 minutes, so please don't shoot me if this isn't exactly correct.

From the diagrams I've looked at, it's coincidental that your device has a garden hose fitting. It operates dry, and simply pushes on the valve actuator. So anyone or their mother can replace one without being scalded.

Ah! You nailed it exactly!
Garden hose thread = coincidence. Meaning: it does not pass water. It's just a clamp. The pin mechanically actuates the cylinder in the widget.

Thank you! Now I can free up that portion of storage and processing to work on Dark Energy.
