Abstract
An automatic fuel supply stopping device incorporated in fuel combustion equipment including a shut-off valve and a combustor. The automatic fuel supply stopping device comprises a fluid intercepting mechanism interposed in a channel through which the fuel supply to the combustor is supplied. A photosensor is adapted to detect fuel combustion in the combustor by radiation emitted from a thermosensitive luminous medium. The fluid intercepting mechanism alternately takes its first stable state or passage blocking state and is changed over, in response to an output from a sensor circuit, from the passage opening state to the passage blocking state.
