Claims (1)
される燃料圧力を調整する燃料圧力調整装置であって、 燃料ポンプから燃料噴射弁に圧送される燃料圧力と、燃
料噴射弁によって燃料噴射される吸気管の圧力とを受け
て、同圧力を比較し、同圧力の差圧が略一定値となるよ
うに燃料圧力を調整するプレッシャレギュレータと、 吸気管圧力を検出し、この圧力が大気圧より高いときに
は、プレッシャレギュレータに供給される吸気管圧力を
遮断し、それに代わってプレッシャレギュレータに大気
圧を供給する切要弁と、を備えることを特徴とする燃料
噴射式エンジンの燃料圧力調整装置。[Scope of Utility Model Registration Claim] A fuel pressure regulating device that regulates the fuel pressure supplied to the fuel injection valve of a fuel injection engine equipped with a supercharger, the fuel pressure being pumped from the fuel pump to the fuel injection valve. and the pressure in the intake pipe where fuel is injected by the fuel injection valve, compare the same pressure, and adjust the fuel pressure so that the differential pressure of the same pressure becomes a substantially constant value; and a cutoff valve that detects the pressure and, when this pressure is higher than atmospheric pressure, cuts off the intake pipe pressure supplied to the pressure regulator and supplies atmospheric pressure to the pressure regulator instead. Fuel pressure regulator for injection type engines.
