The invention relates to an electromagnetically controllable suction valve () for a high-pressure fuel pump (), comprising a magnet assembly () and a hydraulic module (), the hydraulic module () engaging at least in sections in an annular magnet coil () of the magnet assembly (). According to the invention, a heat-conducting material () and/or a heat-conducting body () is/are arranged between the magnet coil () and the hydraulic module (). The invention further relates to a method for producing an electromagnetically actuatable suction valve ().

Electromagnetically actuatable suction valve and method for producing an electromagnetically actuatable suction valve

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.
