GAS REGULATING ACCESSORY Russian patent published in 2008 - IPC F23N5/10 

FIELD: heating; electricity.

SUBSTANCE: gas regulating accessory with device of electronic ignition for gas heating furnaces with natural draught or similar utility incorporates thermo electric valve of safe igniting system and main valve; at that both are designed for safe ignition as well as for separation of gas flow for independent flows for main burner and for igniting burner and which together with auxiliary secondary functional components are arranged in multichambers case; it also incorporates pusher coaxial to thermoelectric valve of safe igniting system and to main valve; this pusher protrudes out of gas directing chamber of case and is designed to move lengthwise in direction counter to effect of return spring force by means of electromagnet. Shut down component is assembled on case; in the first position this component stops pusher and button of piezoelectric component of ignition, while in the second position of shut down component the main valve is closed and there is free access to button and pusher so that they can be activated manually. Shut down component is equipped with a linking guide, tilt of which is made so that main valve is closed at the second position of shut down component. Linking guide can be fixed in the first and second positions of shut down component. Shut down component is made in form of disk, is installed coaxially with journal and is capable to rotate; it also has providing access elements which in the second position of shut down component ensure free access to button and pusher. Pusher is composed of several parts.

EFFECT: invention ensures protection from unauthorized manual ignition of gas flow.
