ル弁より成る実用新案登録請求の範囲第１項記載
の装置。[Scope of Claim for Utility Model Registration] 1. Fuel supply sources for main fuel for normal operation and auxiliary fuel for cold operation are provided independently, and engine intake air is supplied from each fuel supply source. A switching valve that reciprocally changes the passage area of the main fuel and the passage area of the auxiliary fuel is provided in the middle of the fuel passage that supplies fuel to the system, and the switching valve is linked to the chiyoke valve, so that the chiyoke valve closes. A dual fuel supply system for an internal combustion engine in which the auxiliary fuel passage opens when the valve is open, and the main fuel passage opens when the check valve is open. 2. The switching valve is an axially movable needle valve whose tapered portion at one end regulates the passage area of the main fuel passage and whose tapered portion at the other end regulates the passage area of the auxiliary fuel. The device according to item 1.
