Abstract
Es wird ein elektromagnetisch betätigbares Einlassventil (24) für eine Hochdruckpumpe, insbesondere eines Kraftstoffeinspritzsystems, vorgeschlagen. Das Einlassventil (24) weist ein Ventilglied (34) auf, das zwischen einer Öffnungsstellung und einer Schließstellung bewegbar ist. Es ist ein elektromagnetischer Aktor (60) vorgesehen, durch den das Ventilglied (34) bewegbar ist, wobei der elektromagnetische Aktor (60) einen zumindest mittelbar auf das Ventilglied (34) wirkenden Magnetanker (68) und eine den Magnetanker (68) umgebende Magnetspule (64) aufweist. Der Magnetanker (68) ist in einer Ausnehmung (76) eines Trägerelements (78) über seinen Außenmantel hubbeweglich geführt. Die Oberfläche (77) der Ausnehmung (76) des Trägerelements (78) und/oder die Oberfläche (67) des Außenmantels des Magnetankers (68) ist mittels eines Bearbeitungsverfahrens geglättet und/oder kaltverfestigt, insbesondere mittels eines Rollierverfahrens oder Glattwalzverfahrens.An electromagnetically actuatable inlet valve (24) for a high-pressure pump, in particular a fuel injection system, is proposed. The inlet valve (24) has a valve member (34) which is movable between an open position and a closed position. An electromagnetic actuator (60) is provided, through which the valve member (34) is movable, wherein the electromagnetic actuator (60) has a magnet armature (68) acting at least indirectly on the valve member (34) and a magnet coil surrounding the magnet armature (68) (64). The magnet armature (68) is guided in a recess (76) of a support member (78) via its outer jacket liftable. The surface (77) of the recess (76) of the carrier element (78) and / or the surface (67) of the outer jacket of the magnet armature (68) is smoothed and / or work-hardened by means of a machining method, in particular by means of a rolling or smooth-rolling method.
