Abstract

A high-pressure-side valve portion makes contact with and moves from a high-pressure seat surface formed in a body to control communication between a control chamber communication passage and a high-pressure passage. A low-pressure-side valve portion makes contact with and moves from a low-pressure seat surface formed in the body to control communication between an exhaust passage and a second intermediate chamber. A releasing portion in the high-pressure-side valve portion communicates with the control chamber communication passage when the high-pressure seat surface is in contact with the high-pressure-side valve portion to block the control chamber communication passage from the high-pressure passage. A valve element internal passage is formed in the valve element to communicate the releasing portion with the second intermediate chamber.
