Title:
HIGH-PRESSURE FUEL SUPPLY PUMP, AND ASSEMBLY METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/212737
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a high-pressure fuel pump in which the gap between a valve and a rod, which is a cause of valve opening lag in solenoid intake valves, has been reduced. This high-pressure fuel supply pump is characterized by: comprising a magnetic unit obtained by configuring a fixed core, an anchor and a rod as a single unit, an adjuster member that is configured as a separate member from the magnetic unit, and a sheet member that constitutes a valve seat and is positioned such that the adjuster member is sandwiched between the magnetic unit and the sheet member. The high-pressure fuel supply device is further characterized in that when the magnetic unit is attached to the sheet member in a state in which the anchor in contact with the fixed core, the adjuster member forms a gap between the tip of the rod and the valve.
