Title:
SOLENOID VALVE MECHANISM AND HIGH-PRESSURE FUEL SUPPLY PUMP HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2020/213235
Kind Code:
A1
Abstract:
Provided are a solenoid valve mechanism capable of reducing tilt of a movable core during movement; and a high-pressure fuel supply pump having the same. To this end, the solenoid valve mechanism 300 is provided with: a coil 41 provided in an annular shape; fixed cores 44 disposed radially inside the coil 41; movable cores 45 that are disposed radially inside the coil 41 so as to face the fixed cores 44, form a portion of a magnetic circuit together with the fixed cores 44, and are attracted to the fixed cores 44 by the energization of the coil 41; and a fixed guide member 46 that has a first center axis line A3 and guides the movable cores 45 in a direction approach or away from the fixed cores 44. The guide member 46 is disposed radially inside the movable cores 45 and supports the movement of the movable cores 45.
