Abstract
The invention relates to an electromagnetically actuatable intake valve for a high-pressure pump of a fuel injection system, in particular a common rail injection system, comprising a magnet coil () for acting on an armature () which is received and guided such that it can be moved with a reciprocating movement in a central recess () of a valve body (), wherein a pole core () which is connected via a sleeve () to the valve body () lies opposite the armature () at a working air gap (). According to the invention, the valve body () has a circumferential cut-out () within an inner circumferential surface () which delimits the recess (), which cut-out () divides the inner circumferential surface () into an upper and a lower guide region (). The invention also relates to a high-pressure pump for a fuel injection system, in particular a common rail injection system, comprising said type of intake valve.
