を特徴とする複燃料供給装置。 The plunger has a piston that is slid into a cylindrical hole in response to the main fuel pressure in the main fuel pressurizing chamber formed on one side of the main fuel pressurizing chamber, and the piston on the opposite side of the main fuel pressurizing chamber. In a dual fuel supply device in which an auxiliary fuel pressurizing chamber is formed on one side, a labyrinth is installed in the gap between the piston and the cylindrical hole to prevent leakage of the main fuel from the main fuel pressurizing chamber to the auxiliary fuel pressurizing chamber. A dual fuel supply device characterized in that:
