Abstract
A high-pressure fuel accumulator for a fuel injection system of an internal combustion engine, in particular for a common-rail fuel injection system, has an elongated base body having an accumulator space for high-pressure fuel extending in the longitudinal direction of the base body, communicating with multiple connecting bores. A relief space connected to a low-pressure connection is provided in the base body, with a drain channel from the accumulator space opening into it. A pressure regulating valve is installed in the base body for opening and closing the drain channel.
