PROBLEM TO BE SOLVED: To improve volume efficiency and prevent generation of fretting of a valve by forming first and second fuel suction ports and first and second fuel discharge ports provided on a valve performing opening and closing for a low pressure fuel suction passage and a high pressure fuel discharge passage on the outside in the radial direction of an opening part of a fuel pressurizing chamber. SOLUTION: In a high pressure fuel pump 60 supplying fuel within a fuel pressurizing chamber 32 sucked via a low pressure fuel passage 1 by reciprocating motion of a piston according to rotation of a camshaft of an engine to a fuel injection valve via a valve 61 and via a fuel discharge passage, the valve 61 is incorporated together with a housing 37 and a sleeve 72 into a recessed part 10b of a casing 10. The valve 61 is formed by arranging first and second fuel suction ports 66, 68 and first and second fuel discharge ports on the outside in the radial direction of an opening part 200 of the fuel pressurizing chamber 32 on the outer peripheral part. As a result, the vicinities of the fuel suction ports 66, 68 and the fuel discharge ports are pinched by strong force between the casing 10 and the sleeve 72 and generation of a gap can be suppressed. |
