ABSTRACT:
A fuel pressure control valve device comprising: a case; a fuel introducing port and a fuel discharge port; a diaphragm dividing the interior of the case into two chambers; an armature; a resilient member; a pole constituting a fuel passage for discharging fuel; and a sphere as a valve body for opening or closing the fuel passage in the pole. The fuel passage in the pole includes: a fuel passage for guiding the sphere; a valve seat to be abutted against the sphere; and a resilient member for giving a biasing force to the sphere to abut the sphere against the armature. Auxiliary fuel passages are formed in or on the wall of the fuel passage for guiding the sphere. A spring seat is provided at the outer peripheral portion thereof with a stepped portion which receives a coil spring.
