<P>PROBLEM TO BE SOLVED: To provide a fuel supply pump constructed without putting a stopper regulating an open valve position between a valve body and a cylinder body. <P>SOLUTION: The fuel supply pump includes a cylinder body 11 including a pressurizing chamber 113 pressurizing fuel by reciprocating movement of a plunger to an opening end side of a slide hole 111, and a solenoid valve opening and closing a valve hole 35 communicating to the pressurizing chamber 113. The solenoid valve includes a valve body 3 having a seat surface 34 facing the pressurizing chamber 113 formed thereon and including a through-hole 31, and a valve element 4 including a seat part 42 sliding in the through-hole 31 in such a manner that the same can freely reciprocate in the through-hole 31 and opening and closing the valve hole 35 by being separated from and seated on the seat surface 34. A stopper surface 117 regulating a valve open position of the valve element 4 by abutting on the valve element 4 is provided on an end surface at a pressurizing chamber 113 side out of end surfaces at an opening end side of the slide hole 111 in the cylinder body 11. <P>COPYRIGHT: (C)2010,JPO&INPIT |
