Abstract
A damper assembly of a high-pressure fuel pump for reducing fuel pulsation, which is capable of reducing the pulsation of a fuel transferred to the high-pressure fuel pump to stabilize the supply of the fuel, having a simplified structure to minimize an installation space and curtailing manufacturing costs, is provided. The damper assembly of the high-pressure fuel pump includes a damper including upper and lower bodies having flange portions formed along a circumference thereof to face each other in a vertical direction, a retainer ring including a curved portion configured to support the damper and a support portion extending from the curved portion in a longitudinal direction, and a cover member configured to surround the damper and the retainer ring. Here, the damper is fixed in a housing as the flange portion of the upper body, the flange portion of the lower body and the curved portion of the retainer ring are welded at welding portions at the same time.
