As it says on the tin really, it basically stops the cam chain from loosely flapping about, it'll just push against it to keep it reasonably firm in movement.
The tensioner has notches on it, and as the chain wears over time the tensioner will click in a notch to keep the same firmness.
When they've used up all the notches it's normally a sign that you need a new cam chain, and you'll get a warning by the chain making a rattling sound, similar to a sewing machine.
The majority of people will sort it out, simply 'cos the noise drives you barmy, but there are others who live with the noise!

More people are born because of alcohol than will ever die from it.
