| 摘要 |
<p>The present invention relates to a fuel pressure regulator. The fuel pressure regulator includes: a case (3); a valve body (5) which opens and closes a passage (P) connecting a fuel inlet (30) to a fuel outlet (40); an elastic body (7) which opens and closes the passage (P) closed by the valve body (5); a valve sheet (9) which causes the valve body (5) pressurized by the elastic body (7) to be seated on an inner peripheral surface of the passage (P); and a spring sheet (11) which pressurizes the valve body (5) against the valve sheet (9) by the elastic force of the elastic body (7) while supporting the elastic body (7) between the valve body (5) and the elastic body (7), wherein the spring sheet (11) is supported to the case (3) to be elastically deformed by the elastic body (7), and is elastically restored while being pressurized by the valve body (5) when the valve body (5) opens and closes the passage (P). Therefore, fuel pressure can be stably maintained by controlling that the fuel pressure against the valve body rises sharply.</p> |
