Beschreibung
Zusammenfassung:	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 (1) for acting on an armature (2) which is received and guided such that it can be moved with a reciprocating movement in a central recess (3) of a valve body (4), wherein a pole core (6) which is connected via a sleeve (7) to the valve body (4) lies opposite the armature (2) at a working air gap (5). According to the invention, the valve body (4) has a circumferential cut-out (9) within an inner circumferential surface (8) which delimits the recess (3), which cut-out (9) divides the inner circumferential surface (8) into an upper and a lower guide region (10, 11). 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.
