Abstract
The invention takes as a basis the problem of developing a thermo-electric safety igniter with a reignition lock on a gas valve combination which is suitable for using a rotary slide as main valve for the main gas flow and the pilot gas flow. The problem is solved in that a half-disc, whose ends are located in a notch, is arranged on part of the operating rod intruding into the housing chamber such that when the main valve is closed and the valve head of the safety igniter valve is in the open position, the ends of the half disc cooperate with the notch to prevent opening movement of the main valve. The hoop has a blade or tongue whose length is dimensioned such that the hoop ends are moved out of the notch when the igniter safety valve closes and the main valve remains closed. The invention refers to a thermo-electric safety igniter with a reignition lock on a gas valve combination for a gas heating furnace or similar for controlling the main gas flow and the pilot gas flow.
