Thermoelectric safety actuator adapted to a gas burner of a domestic appliance

摘要

Thermoelectric safety actuator for a burner that comprises an electromagnet (21) connectable to a thermocouple and to auxiliary energising means adapted to keep said electromagnet (21) energised until the thermocouple is able to keep it energised, a frame (20), and a sealing member (23) attached to the frame (20). The actuator (10) comprises a swinging arm (22) on the first end (22a) of which the frame (20) is arranged fixed and on the second end (22b) of which the sealing member (23), the arm (22) swinging between a rest position wherein the passage of gas to the burner is closed and an activation position wherein the electromagnet (21) is energised and the passage of gas open, the electromagnet (21) initially being energised by the auxiliary energising means and being kept energised by said energising means until the thermocouple is able to keep it energised.
