- ガス通路途中に弁体部材を設け、この弁体部材の一端に設けた弁体部でガス通路を開閉すると共に、弁体部材の他端に可動鉄片を設け、かつ、この可動鉄片に対してモータにより少なくとも磁極が進退する電磁石を設けて、励磁した状態でこの電磁石の磁極を可動鉄片に接触させることにより可動鉄片を磁極に吸着させ、その吸着させた状態のままモータにより電磁石の磁極を移動させて、弁体部を開弁させるモータ安全弁において、電磁石の磁極を励磁させる励磁コイルに通電状態で、電磁石の両磁極に可動鉄片が吸着され閉磁路が構成された瞬間、及び、同じく励磁コイルに通電状態で吸着されている可動鉄片が電磁石の磁極から離れて開磁路になった瞬間に誘導される誘導電流に基づき、電磁石の磁極に対する可動鉄片の吸着および離脱を検知するようにしたことを特徴とするモータ安全弁。
