装置。In a fuel pressure regulating device for an internal combustion engine, in which surplus fuel in a fuel supply passage is diverted and returned to a fuel tank, a first regulator is interposed in the middle of the fuel supply passage, the valve of which opens due to a pressure difference between the negative pressure of an intake pipe, and A second regulator is interposed in the middle of a fuel return passage that returns surplus fuel from the first regulator to the tank, and the second regulator defines a tire flam chamber by a tire flam that controls the fuel return pressure.
A fuel pressure regulating device for an internal combustion engine, characterized in that a volatile liquid that evaporates depending on the fuel temperature is sealed in a tire flam chamber.
