Abstract

Valve arrangement for pressure regulation of fuel introduction in an internal combustion engine having a pressure regulation and a shutoff function that can be actuated by an electromagnetic drive. A housing is provided with at least one inlet connection and at least one outlet connection, which are connected to one another by a connection channel. The electromagnetic drive includes an armature which acts on a tappet supporting a closing element, which opens or closes the connection channel. At least one pressure spring element acts on the closing element either directly or indirectly in the closing direction. The armature is supported by a core which can adjust the electromagnetic force applied to the armature.
