Arrangement for adjusting valve, has plunger which is under action of restoring element, where valve closing unit has housing attached to valve

摘要

The arrangement (11) has a plunger (21) which is under an action of a restoring element (23). A valve closing unit (18) has a housing (31) attached to a valve (12), and is arranged to a temperature-dependent actuating element (41) which interacts with an actuating device (34). The actuating device is activated by the actuating element to move between a rest position (57) and a working position. The actuating element is formed as spring element from a shape-memory alloy.
