プレッシャレギュレータ
Document Type and Number:
Japanese Patent JP5316720
Kind Code:
B2
Abstract:
A pressure regulator is connected to a fuel pipe to which fuel is supplied by a feed pump. There is formed a fuel channel in the pressure regulator for returning fuel from within the fuel pipe to the fuel tank. In the pressure regulator, there are also formed a stopper and a valve body which collectively reduce the fuel flow area of the fuel channel as a result of an increase in the fuel pressure within the fuel pipe. This makes the fuel within the fuel pipe less likely to be released through the aforementioned fuel channel. For this reason, it is possible to correspondingly increase the fuel pressure within the fuel pipe in an efficient manner by increasing operating rate of the feed pump under conditions where the fuel pressure within the fuel pipe is high.
