Hi there...one study determined that purring involves activation of nerves within the voice box. These nerve signals cause vibration of the vocal cords while the diaphragm serves as a pump, pushing air in and out of the vibrating cords, thus creating a musical hum. Some veterinarians believes that purring is initiated from within the central nervous system and is a voluntary act. In other words, cats purr only when they want to.
The other theory is that the sound comes more from vibrating blood vessels than in the voicebox itself.

For one thing, scientists still "have no idea" how cats purr! So, part of it is they "believe" utilizing the vocal chords which has nothing to do with breathing. Other than that, who knows?

Cats can purr during both inhalation and exhalation, so it's not related to whether or not they're breathing.

That answer is still being looked for but it has been found that the diaphragm and larynx is used while they purr. Check out the sites below for more details.

Purring is part of every cat's repertoire of social communication, apparently created by the movement of air in spasms through contractions of the diaphragm. Interestingly, purring is sometimes heard in cats who are severely ill or anxious, perhaps as a self-comforting vocalization. But, more typically, it is a sign of contentment, first heard in kittens as they suckle milk from their mother.

It doesn't involve their lungs or vocal chords. I'm not sure how they do it but it sure is a wonderful sound when your kitty does it!
