Title: Pressure control valve
Inventor: HAGIWARA SHINICHI
IPC: F02M69/00
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of a sound by a pressure reduction boiling while suppressing an increase in cost. SOLUTION: In this control valve 10, the pressure in a fuel feed passage is maintained constant by opening a valve hole 20 by a valve disk 22 following to the displacement of a diaphragm 18, when the pressure led in from a fuel feeding hole 12 to the inside of a fuel storing chamber 13 exceeds a set value, and by returning the excessive fuel in the fuel storing chamber 13 to the fuel tank from the valve hole 20 through a return pipe 31. In this case, a leading-in hole 33 is opened to the bending part 32 of the return pipe 31 in order to communicate the inner side and the outer side of the return pipe 31.  Since a pressure reduction boiling phenomenon generated by an excessive fuel discharged from the valve hole 20 is prevented by leading in the atmosphere in the tank into the return pipe 31 from the leading-in hole 33, the generation of bubbles by the pressure reduction boiling is prevented, and the generation of the breaking sound of bubbles, and the resonance sound following that, can be prevented. As a result, an increase in cost can be prevented because it is necessary only to provide the above leading-in hole.
