を特徴とする複燃料供給装置。 It includes a main fuel injection pump that pumps the main fuel to the injection nozzle, and an auxiliary fuel pump that pumps the auxiliary fuel to the injection nozzle in conjunction with the main fuel injection pump,
The auxiliary fuel pressure feeder includes a cylinder, a pressurizing piston slidably inserted into the cylinder, and a spring that biases the pressurizing piston in the sliding direction. In the dual fuel supply device in which a sub-fuel pumping chamber is formed by an end of the pressurizing piston, the cylinder of the sub-fuel pumping device includes a cylinder located on the outer periphery of the pressurizing piston and independent from the pressurizing chamber. 1. A dual fuel supply device comprising: a spring chamber provided with a pressure spring; and the biasing spring is housed in the spring chamber so as to surround the outer periphery of the pressurizing piston.
