What is this?

What is the plastic ball shaped part in my engine compartment. It has 2 vacuum lines. And what is its purpose?

It's probably a vacuum tank. Not sure without an image.

Vacuum reservoir. It holds vacuum so that the climate controls still work even when the engine is under load and not producing enough vacuum to power them.

And cruise/emissions stuff depending on era.

Excellent, I figured it was related to my climate control. Wasn't sure what to call it.
