Abstract
The present invention relates to a valve having a base body with a passage opening, a movable valve member for closing and opening the passage opening and an actuating mechanism for moving the valve member in order to open the passage opening. The actuating mechanism has at least two elements made from a shape memory alloy which are secured to the base body or a carrier body connected thereto, and can be alternately shortened in the event of the temperature rising above a threshold temperature and are connected to the valve member in such a way that the valve member can be moved from a position on the passage opening into a position alongside the passage opening when one element is shortened on one side and can be moved back into the position on the passage opening when the other element is shortened on one side.
