Abstract
A thermally controlled valve is provided having a valve seat, a closure valve cooperating with the valve seat, a diaphragm capsule, a plate spring, and an abutment supporting the plate spring along its outer edge. The diaphragm capsule includes a rigid wall part and a diaphragm component actuating the closure valve, the wall part and the diaphragm component being joined with each other along their outer edges and forming a reservoir therebetween for an evaporation medium. The plate spring rests against the face side of the diaphragm component which is averted from the wall part of the diaphragm capsule, and the inner edge of the plate spring engages the closure valve so as to act thereon in the opening direction.
