<p>A fuel injection pump for internal combustion engines having an equal-pressure relief valve, which has a structure requiring little space when installed and is provided with a fastener element. The equal-pressure relief valve comprises a pressure valve body, onto which a beaker-shaped filler piece protruding into the interior of the pressure valve spring is placed. The structural unit comprising the pressure valve body and the filler piece containing the relief valve is held together, even when the pipe connector fitting or the pressure valve spring is removed, by means of the transit fastener element provided with a fastener ring. The invention is applicable both to single and series fuel injection pumps as well as to distributor injection pumps, particularly when space for installation is restricted.</p> |
