力制御装置。 A fuel pressure adjustment chamber is located on one side of the pressure responsive member.
A fuel chamber is formed on the other side, and a pressure regulating valve is provided for adjusting the pressure on the fuel chamber side by swinging a pressure responsive member in response to a pressure change in the fuel pressure regulating chamber, and a passage communicating with the fuel supply means to the fuel chamber. A return pipe that opens and closes by the swinging of the pressure responsive member is connected, a switching valve is connected to the fuel pressure adjustment chamber, and one switching port of the switching valve is used to guide the engine's intake negative pressure. A fuel pressure control device, characterized in that it is provided with a control means that communicates with a negative pressure pipe, communicates the other switching port with a positive pressure pipe that leads positive pressure from an air pressure feeding means, and switches the two switching ports depending on the operating state.
