Abstract
Description
Die vorliegende Erfindung bezieht sich auf eine elektromagnetische Ventilvorrichtung, die ein Ventilgehäuse aufweist, in dem sich ein Ventil der Spulenbauweise axial bewegt, um eine in dem Ventilgehäuse ausgebildete Öffnung zu ändern, um eine Menge eines Fluids, etwa eines Kraftstoffs, Öls oder von Luft zu dosieren, und insbesondere auf eine elektromagnetische Ventilvorrichtung, die in einer Kraftstoffzuführpumpe eines Kraftstoffeinspritzsystems der Common-Rail-Bauweise montiert ist, um eine Menge von zu einer Druckkammer der Pumpe zugeführtem Kraftstoff zu dosieren.The The present invention relates to an electromagnetic valve device, the one valve housing in which a valve of the coil design moves axially, around one in the valve body trained opening to change, by a quantity of a fluid, such as a fuel, oil or of Dosing air, and more particularly to an electromagnetic valve device, in a fuel supply pump a common-rail fuel injection system mounted is to a lot of fuel supplied to a pressure chamber of the pump to dose.
In einem Kraftstoffeinspritzsystem der Common-Rail-Bauweise wird hochdruckbeaufschlagter Kraftstoff in einer Common-Rail gesammelt, so dass der in der Common-Rail gesammelte Kraftstoff zu einer Vielzahl von Zylindern einer Kraftmaschine über an den jeweiligen Zylindern montierte Injektoren bei einer geeigneten Kraftmaschinenzeitgebung zugeführt wird. In dem Kraftstoffeinspritzsystem der Common-Rail-Bauweise wird von einem Kraftstofftank über eine elektromagnetische Ventilvorrichtung in die Druckkammer der Kraftstoffzuführpumpe geholter Kraftstoff durch die Pumpe druckbeaufschlagt und über ein Kraftstoffbeschickungsrohr so zu der Common-Rail zugeführt, dass der druckbeaufschlagte Kraftstoff immer in der Common-Rail angesammelt wird.In A common rail fuel injection system becomes high pressure fuel collected in a common rail, so that collected in the common rail Fuel to a variety of cylinders of an engine over to the injectors mounted on respective cylinders at a suitable engine timing supplied becomes. In the common rail fuel injection system gets over from a fuel tank an electromagnetic valve device in the pressure chamber of fuel feed fuel is pumped through the pump and over a Fuel feed pipe so supplied to the common rail that the pressurized fuel is always accumulated in the common rail.
Die Menge des von der Kraftstoffzuführpumpe ausgelassenen Kraftstoffs wird gemäß der Menge des durch eine Förderpumpe über einen Kraftstoffeinlassdurchlass und ein Ansaugventil in die Druckkammer geholten Kraftstoff gesteuert. D.h., die Menge des in die Druckkammer geholten Kraftstoffs wird durch eine elektromagnetische Ventilvorrichtung gesteuert, die die offene Fläche des Kraftstoffeinlassdurchlasses gemäß dem dazu zugeführten Spannungsbetrag ändert. Der zu dem elektromagnetischen Ventil zugeführte Spannungsbetrag wird gemäß dem Betrag der Antriebsspannung der Kraftstoffzuführpumpe gesteuert. In der vorgenannten elektromagnetischen Ventilvorrichtung ist es schwierig, einen zwischen der Außenfläche eines Ventilelements und der innenseitigen Wand eines Ventilgehäuses der Spulenbauweise ausgebildeten gleichmäßigen Spalt bereitzustellen. In diesem Fall wird ein gleichmäßiges Magnetfeld nicht ausgebildet, was dazu führt, dass das Ventilelement in dem Ventilgehäuse nicht zentriert werden kann. Folglich kann die äußere Gleitfläche des Ventilelements die innenseitige Wand des Ventilgehäuses ungleichmäßig kontaktieren und das Ventilelement kann sich in dem Ventilgehäuse nicht problemlos bewegen. Dies kann eine ungenaue Dosierung des Kraftstoffs hervorrufen, was wiederum einen ungenauen Druck in der Common-Rail und eine ungenaue Kraftstoffeinspritzung in eine Kraftmaschine verursacht.The Amount of that from the fuel supply pump discharged fuel is in accordance with the amount of by a Feed pump via a Fuel inlet passage and a suction valve in the pressure chamber fetched fuel controlled. That is, the amount of the fetched into the pressure chamber Fuel is passed through an electromagnetic valve device controlled the open area of the fuel inlet passage according to the amount of voltage supplied thereto. Of the the amount of voltage supplied to the electromagnetic valve becomes in accordance with the amount the drive voltage of the fuel supply pump controlled. In the aforementioned electromagnetic Valve device, it is difficult to between the outer surface of a Valve element and the inside wall of a valve housing the Coil design trained to provide uniform gap. In this case, a uniform magnetic field not trained, which leads to that the valve element in the valve housing are not centered can. Consequently, the outer sliding surface of the Valve element contact the inside wall of the valve body unevenly and the valve element can not easily move in the valve housing. This can cause inaccurate metering of the fuel, which again an inaccurate pressure in the common rail and an inaccurate Fuel injection into an engine causes.
Beispielsweise offenbart die JP-A-2002-106740 eine elektromagnetische Ventilvorrichtung, die ein Ventilgehäuse, ein in dem Ventilgehäuse verschieblich angeordnetes Ventilelement, einen Statorkern, der mit dem Anker einen Magnetkreislauf ausgebildet, und eine Solenoidspule zum Magnetisieren des Ankers und des Statorkerns aufweist. Der Anker ist aus Weicheisen gefertigt und das Ventilelement ist aus abnutzungsresistentem Material gefertigt oder damit beschichtet. Wenn der Anker an das Ventilelement zwangsgepasst wird, kann der Rand des Ventilelements verformt werden. Dementsprechend kann sich das Ventilelement nicht problemlos in dem Ventilgehäuse bewegen, so dass die Menge des in die Druckkammer genommenen Kraftstoff nicht präzise gesteuert werden kann. Als ein Ergebnis kann der druckbeaufschlagte Kraftstoff eines geeigneten Drucks nicht in der Common-Rail angesammelt werden, wodurch eine ungenaue Kraftstoffeinspritzung verursacht wird.For example JP-A-2002-106740 discloses an electromagnetic valve device, the one valve housing, in the valve housing slidably disposed valve element, a stator core, the formed with the armature a magnetic circuit, and a solenoid coil for magnetizing the armature and the stator core. The anchor is made of soft iron and the valve element is made of wear resistant Material made or coated with it. When the anchor to the Valve element is forcibly fitted, the edge of the valve element be deformed. Accordingly, the valve element can not move easily in the valve body, so that the amount of fuel taken into the pressure chamber is not precise can be controlled. As a result, the pressurized Fuel of a suitable pressure is not accumulated in the common rail which causes inaccurate fuel injection becomes.
