Abstract: A magnet valve that serves to block off a fuel intake line to control fuel flow to supply a pump work chamber of a fuel injection pump with fuel, a closing element has a bore entering at the face end, which bore can be closed by a valve member under the influence of a closing spring. When pressure surges occur in one part of the intake line which is closed by the closing element and leading to the pump work chamber, instead of the closing element and the entire cross section of the intake line portion being opened, only the cross section of the bore is opened. Once it has been pushed open, this bore is rapidly closed again by the low-mass valve member, so that only small quantities of fuel can flow via the bore for pressure equalization.
