Abstract
The support of a relief valve in a constant pressure relief valve of the fuel injection pump comprises a bolt and two openings for receiving it in the sheath-like wall of the movable valve closing body. The openings are embodied by a bore drilled through the wall of the valve closing body at right angles to the longitudinal axis of the valve closing body. The bolt receives a spring plate of a spring of the relief valve in a depression and is thereby positioned and secured.
