Abstract
The pressure regulator is suitable for disposition in a fuel pump. The pressure regulator has a metal bellows, which is connected on one end to a retaining ring and on the other end to a disk. An element is screwed into the retaining ring, which element carries a valve closing member of a seat valve, whose valve seat encompasses an outlet bore of the disk. The interior of the bellows communicates with the compression side of the fuel pump by means of an opening of the element, and with the intake side by means of the outlet bore of the disk.
