ELECTROMAGNETICALLY ACTUATED SUCTION VALVE FOR A HIGH-PRESSURE PUMP, AND METHOD FOR MANUFACTURING A SUCTION VALVE OF SAID TYPE

摘要

The invention relates to an electromagnetically actuated suction valve for a high-pressure pump of a fuel injection system, in particular a common rail injection system, comprising an annular electromagnetic coil (1) for acting on an armature (2) which is accommodated in a cavity (3) of a valve body (4) so as to be liftable and to which the spring force of an armature spring (7) is applied in the direction of a liftable valve-closing element (6) cooperating with a valve seat (5); a pole core (9) that is permanently connected to the valve body (4) lies across from the armature (2) at an operational air gap (8). According to the invention, the armature spring (7) is supported on the armature (2) and on an adjusting element (10) that is inserted into a central cavity (11) in the pole core (9). The invention further relates to a method for manufacturing a suction valve of said type.
