Abstract (en)

[origin: WO9105950A1] In a magnetic valve serving to block a fuel inlet line (10) to supply a pump working chamber of a fuel injection pump with fuel, the closing component (28) has a drilling (50) penetrating from the front which can be closed off by a valve member (61) under the action of a closing spring (57). On the occurrence of pressure surges in the intake line section (31) closed off by the closing member (28) and leading to the pump working chamber, the closing member (28) and the entire cross-section of the intake line section (31) is not opened but only the cross-section of the drilling (50). This drilling is quickly closed again by the low-mass valve member (61) after the surge has passed so that only small quantities of fuel can flow via the drilling (50) to equalise the pressure.
