<P>PROBLEM TO BE SOLVED: To provide a pressure adjustment device capable of suppressing the damage of a diaphragm. <P>SOLUTION: When the fuel pressure of the fuel supply path of a fuel supply system is adjusted to second predetermined pressure by a high-pressure pressure regulator, even if the second predetermined pressure higher than first predetermined pressure being the pressure adjustment value of a low-pressure pressure regulator 10 is applied to the low-pressure pressure regulator 10, a stopper 70 regulates the displacement of a valve element 52 in an opposed seating direction so that the diaphragm 30 is not brought into a stretched state in a radial direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
