Abstract
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 () that engages with a valve seat () and is loaded in the closing direction by the spring force of a valve spring () which is supported on a spring plate () connected to the valve closure element (), further comprising a reciprocating armature () that engages with an electromagnet () and is loaded in the direction of the valve closure element () by the spring force of an armature spring () which is larger than that of the valve spring (). According to the invention, the spring plate () has a first abutment face () for limiting the opening travel of the valve closure element () and a second abutment face () for mechanically coupling to the armature (). The invention also relates to a high-pressure pump having such an intake valve.
