Abstract
The present invention relates to a screen. The screen a) is annular, b) is designed to filter water in a thermostatic valve, c) can be transferred from a first state into an additional state, d) has a first circumference in the first state, and e) has an additional circumference in the additional state. The screen is characterized in that the additional circumference is greater than the first circumference.
