Document Type and Number:
Japanese Patent JP2016188577
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a high-pressure fuel supply pump that can inhibit inclination of a valve body and constrain the valve body so as to be slidable in an axial direction, whereby a seat surface of the valve body can come into contact with a seat part further strongly.SOLUTION: The high-pressure fuel supply pump includes: a compression chamber for compressing fluid; and a discharge valve disposed between the compression chamber and a discharge passage. The discharge valve includes: a part to be guided that is formed on a side opposite to the compression chamber: and a guiding part disposed on a side opposite to the compression chamber relative to the discharge valve to guide a sliding part of the part to be guided.SELECTED DRAWING: Figure 4
