Claims (1)
へ逃すリリーフ通路と、上記燃料チヤンバ内の燃
料圧力が設定圧以下のときにリリーフ通路の通路
面積を減少させる弁機構と、上記弁機構の弁体に
連係させて弁機構に組込まれ燃料チヤンバ内の燃
料温度が低いときに収縮して上記設定圧を高圧側
へ変化させる感温部材とを備えたデイーゼルエン
ジンの始動進角制御装置において、 上記感温部材の周辺に感温部材を加熱するヒー

角制御装置。[Scope of Claim for Utility Model Registration] A relief passage that releases the fuel in the fuel chamber of the fuel injection pump to the outside, and a valve mechanism that reduces the passage area of the relief passage when the fuel pressure in the fuel chamber is below a set pressure. and a temperature-sensitive member that is incorporated into the valve mechanism in conjunction with the valve body of the valve mechanism and contracts when the fuel temperature in the fuel chamber is low to change the set pressure to a high pressure side. The angle control device is characterized in that a heater for heating the temperature sensing member is disposed around the temperature sensing member, and a control means is provided for energizing the heater when the engine cooling water temperature is higher than a predetermined temperature. Diesel engine starting advance angle control device.
