Abstract

Es wird ein Magnetventil mit einstellbarem Ankerhub, insbesondere für einen Kraftstoff-Injektor einer Brennkraftmaschine vorgeschlagen. Das Magnetventil (20) weist einen in einem Magnetventilgehäuse (26) angeordneten Magnetanker zur Betätigung eines Ventilgliedes auf, das in einem Ventilgehäuse (11) angeordnet ist. Zwischen dem Magnetventilgehäuse (26) und dem Ventilgehäuse (11) ist ein Abstand einstellbar, der den Ankerhub bildet, wobei das Magnetventilgehäuse (26) und das Ventilgehäuse (11) mittels einer Spannmutter (29) verbunden sind. Zwischen dem Magnetventilgehäuse (26) und dem Ventilgehäuse (11) ist ein elastisch verformbarer Distanzring (30) angeordnet, wobei durch eine Verformung des Distanzrings (30) der Ankerhub einstellbar ist. Als Distanzring (30) wird ein elastisch verformbarer metallischer Hohlring verwendet.

It is proposed a solenoid valve with adjustable armature stroke, in particular for a fuel injector of an internal combustion engine. The solenoid valve (20) has a magnet armature arranged in a solenoid valve housing (26) for actuating a valve member which is arranged in a valve housing (11). Between the solenoid valve housing (26) and the valve housing (11), a distance is adjustable, which forms the armature stroke, wherein the solenoid valve housing (26) and the valve housing (11) by means of a clamping nut (29) are connected. Between the solenoid valve housing (26) and the valve housing (11) an elastically deformable spacer ring (30) is arranged, wherein by a deformation of the spacer ring (30) of the armature stroke is adjustable. As a spacer ring (30), an elastically deformable metallic hollow ring is used.
