<P>PROBLEM TO BE SOLVED: To expand a fuel pressure range in which a fuel pulsation reducing device can reduce pulsation in the fuel pulsation reducing device reducing the pulsation generated in a fuel passage of an internal combustion engine. <P>SOLUTION: The fuel pulsation reducing device including a first partition wall and a second partition wall that is elastically supported in a housing includes: a first chamber that is defined by the first partition wall and the housing, and communicated with the fuel passage of the internal combustion engine; a second chamber that is defined by the second partition wall and the housing, and communicated with the fuel passage via a throttle; a third chamber that is defined by the first and second partition walls and communicated with atmosphere; and a spring that is housed in the third chamber and one end of which is connected to the first partition wall and the other end of which is connected to the second partition wall. A pressure receiving surface of the first partition wall is expanded compared to one of the second partition wall. <P>COPYRIGHT: (C)2013,JPO&INPIT |
