    摘要: The invention relates to an electromagnetically actuable intake valve for a high-pressure pump of a fuel injection system, in particular of a common-rail injection system, comprising a reciprocating valve closure element (2) that engages with a valve seat (1) and is loaded in the closing direction by the spring force of a valve spring (3) which is supported on a spring plate (4) connected to the valve closure element (2), further comprising a reciprocating armature (6) that engages with an electromagnet (5) and is loaded in the direction of the valve closure element (2) by the spring force of an armature spring (7) which is larger than that of the valve spring (3). According to the invention, the spring plate (4) has a first abutment face (9) for limiting the opening travel of the valve closure element (2) and a second abutment face (10) for mechanically coupling to the armature (6). The invention also relates to a high-pressure pump having such an intake valve.

    摘要: The invention relates to an electromagnetic actuating unit for an intake valve for supplying fuel to a high-pressure fuel pump, in particular a high-pressure common-rail pump, comprising an electromagnet (1) and an armature (2) which is guided, in an armature guide (3) surrounding an outer circumferential region of the armature (2), so as to be axially displaceable. According to the invention, the armature guide (3) serves at the same time for mounting the armature , the armature (2) being in the form of a flat armature that bounds an axial working air gap (4) formed between the armature (2) and the electromagnet (1). The invention further relates to an intake valve having such an electromagnetic actuating unit.

    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 a magnetic subassembly (1) that includes an annular electromagnetic coil (2) for acting on an armature (3) which is accommodated in a cavity (4) of a valve body (5) so as to be liftable and to which the spring force of an armature spring (8) is applied in the direction of a liftable valve-closing element (7) cooperating with a valve seat; a pole core (10) lies across from the armature (3) at an operational air gap (9). The invention is characterized in that the pole core (10) penetrates a pole disk (11) and is decoupled from the pole disk (11) by a circumferential radial gap (12). The invention further relates to a high-pressure pump comprising a suction valve of said type.
