Abstract

Die Erfindung betrifft ein Druckregelventil (1), insbesondere für einen Hochdruckspeicherkörper oder eine Hochdruckförderpumpe eines Kraftstoffeinspritzsystems, umfassend
- ein Ventilgehäuse (2, 2a, 2b) mit einer axialen Ventilstößelbohrung (7) zur Aufnahme eines Ventilstößels (6) und mit einer die Ventilstößelbohrung (7) umlaufenden Ausnehmung (27) zu Aufnahme einer Magnetspule (3),
- eine mit dem Ventilstößel (6) verbundene Ankerplatte (17), und
- ein mit dem Ventilstößel (6) in Wirkverbindung stehenden Sitzventil (4);
The invention relates to a pressure control valve (1), in particular for a high-pressure accumulator body or a high-pressure pump of a fuel injection system, comprising
- A valve housing (2, 2a, 2b) with an axial valve stem bore (7) for receiving a valve stem (6) and with a valve stem bore (7) circumferential recess (27) for receiving a magnetic coil (3),
- An anchor plate (17) connected to the valve stem (6), and
- One with the valve stem (6) operatively connected seat valve (4);

Erfindungsgemäß ist vorgesehen, dass der Magnetkreis (25) der Magnetspule (3), der von dem die Magnetspule (3) aufnehmenden Bereich des Ventilgehäuses (2, 2a, 2b) und von der Ankerplatte (17) gebildet wird, wenigstens eine magnetische Einschnürung (26, 26 `, 26", 17, 31) aufweist.

Figure imgaf001
According to the invention, the magnetic circuit (25) of the magnetic coil (3), which is formed by the region of the valve housing (2, 2a, 2b) receiving the magnetic coil (3) and the armature plate (17), has at least one magnetic constriction (FIG. 26, 26 `, 26", 17, 31).
