Abstract
Description
Die Erfindung betrifft ein Druckventil für eine hydraulische Anlage, insbesondere für ein Hochdruck-Kraftstoffsystem, nach dem Oberbegriff des Anspruchs 1.The The invention relates to a pressure valve for a hydraulic system, especially for a high-pressure fuel system, according to the preamble of the claim 1.
Druckventile, die als Druckbegrenzungsventile oder als Druckregelventile ausgebildet sein können, sind bekannt und dienen zur Steuerung des Druckmitteldruckes in einer hydraulischen Anlage. Bei bekannten Druckventilen wirkt beispielsweise ein Elektromagnet über einen Anker direkt, seltener indirekt über eine Druckfeder auf ein Ventil. Das Steuerelement des Ventils ist überwiegend als Sitzkegel, seltener als Längsschieber oder Düsen-Prallplattensystem ausgebildet. Es kann die auf das Steuerelement ausgeübte Magnetkraft – und damit der Druckmitteldruck in der hydraulischen Anlage – durch Variieren des elektrischen Eingangsstromes variiert werden, ohne dass der elektromagnetische Wandler einen Hub ausführt. Der Wandler wirkt als elektromagnetische Feder.Pressure valves, designed as pressure relief valves or pressure control valves could be, are known and are used to control the fluid pressure in a hydraulic system. For example, in known pressure valves an electromagnet over an anchor directly, more rarely indirectly via a compression spring on Valve. The control of the valve is predominantly as a seat cone, rare as a longitudinal slide or nozzle baffle system educated. It can be the force exerted on the control magnetic force - and thus the fluid pressure in the hydraulic system - by Varying the electrical input current can be varied without that the electromagnetic transducer performs a stroke. Of the Transducer acts as an electromagnetic spring.
Bei den bekannten Druckventilen ist der Anker in dem Ventilgehäuse in einer Gleitoder Schlichtgleitsitzpassung axialverschieblich geführt. Bei Tauchankern mit großer axialer Erstreckung kann es insbesondere verbunden mit Druckmitteleinflüssen des in dem Anker vorhandenem Druckmittels zu Hystereseeffekten beim Stellvorgang des Druckventils kommen. Zudem ist der Bearbeitungsaufwand eines solchen Ankers nicht optimiert.at the known pressure valves, the armature in the valve housing in one Gleitoder Schlichtgleitsitzpassung guided axially displaceable. For diving anchors with big ones axial extent, it may in particular associated with pressure medium influences of the in the anchor existing pressure medium to hysteresis effects Stellvorgang the pressure valve come. In addition, the processing cost of such an anchor not optimized.
Der Erfindung liegt die Aufgabe zugrunde ein Druckventil zu schaffen, das bei optimiertem Herstellungsaufwand im Betrieb verschleißarm und leichtgängig ist. Das Ventil soll als Hochdruckregelventil verwendbar sein.Of the Invention has for its object to provide a pressure valve, the wear-optimized at an optimized production cost in operation and smooth is. The valve should be usable as a high pressure control valve.
Die Aufgabe wird mit einem Druckventil mit den Merkmalen des Anspruchs 1 gelöst.The Task is with a pressure valve with the features of the claim 1 solved.
Dadurch, dass der Anker eine größere Maßtoleranz hat, die zumindest in der Kategorie Laufsitztoleranz (H7/f1) oder größer liegt, und der Anker mit einem Ankersitz zur Zentrierung und Führung des Ankers in dem Ventilgehäuse verbunden ist, wobei der Ankersitz eine kleinere Maßtoleranz – etwa Gleitsitz- oder Schlichtgleitsitztoleranz (H7/h6) aufweist, ist eine konstruktive Maßnahme getroffen, den Bearbeitungsaufwand des Druckventils zu senken und einen dauerhaften hysteresearmen oder -freien Betrieb des Druckventils zu ermöglichen.Thereby, that the anchor has a greater dimensional tolerance has, at least in the category Laufsitztoleranz (H7 / f1) or is larger, and the anchor with an anchor seat for centering and guiding the anchor in the valve housing the anchor seat has a smaller dimensional tolerance - such as sliding fit or slip clearance tolerance (H7 / h6) is a constructive one measure taken to reduce the processing cost of the pressure valve and a permanent hysteresis-poor or-free operation of the pressure valve to enable.
Eine weitere Besonderheit bei dem vorliegenden Ventil besteht darin, dass es sich um einen Tauchanker handelt, der von dem unter hochdruckstehenden Medium beiderseits zur Bewegungsrichtung umspült wird. Hierzu weist der Anker ein Durchgangsloch zur Kavität, die die Ankerfeder aufnimmt, auf, so dass auch die Ankerfeder mediumumspült im Druckbereich vorhanden ist.A another special feature of the present valve is that it is a plunger anchor, which is under high pressure Medium is washed around on both sides to the direction of movement. For this purpose, the anchor points a through hole to the cavity, which receives the armature spring, on, so that the armature spring medium-washed in the pressure range is available.
Unter dem Begriff Hochdruck versteht man, wenigstens pulsationsweise auftretende Drücke von bis zu 40 bar und darüber, wobei der Betriebsdruck permanent nur 4 bar betragen soll.Under The term high pressure is understood to mean, at least pulsation occurring pressures up to 40 bar and above, the operating pressure should be permanently only 4 bar.
Bevorzugte Ausführungen ergeben sich aus den Unteransprüchen.preferred versions emerge from the dependent claims.
Der Ankersitz weist bevorzugt eine Rundpassung auf. Der Anker ist zu dem Ankersitz mit einem Dichtelement, das bevorzugt eine Elastomerdichtung ist, die in einer Nut an dem Ankersitz liegt, in Anlage. Der Anker liegt bevorzugt mit einer Umfangs-Außenkante an dem Dichtelement etwa in dessen Mitte an.Of the Ankeritz preferably has a round fit. The anchor is too the anchor seat with a sealing element, which is preferably an elastomeric seal is in a groove on the anchor seat, in plant. The anchor preferably lies with a circumferential outer edge on the sealing element in the middle of it.
Der Ankersitz kann aus einem Edelstahlrohr oder einer Kunststoffhülse oder aus einem Materialverbund von Kunststoff und Metall gebildet sein. Der Anker kann gleichzeitig der Ventilstößel des Druckventils sein und in einem druckausgeglichenen Ankerraum des Druckventils angeordnet sein.Of the Ankersitz can be made of a stainless steel tube or a plastic sleeve or be formed of a composite material of plastic and metal. The armature can be at the same time the valve stem of the pressure valve and arranged in a pressure balanced armature chamber of the pressure valve be.
Der Anker kann nach einer vorteilhaften Ausgestaltung verchromt sein. Es fördert die Laufeigenschaften des Ankers. Alternativ kann die Buchse, in der der Anker läuft, auch als Edelstahl gefertigt sein. Bei ähnlichen Laufeigenschaften ist der Anker dann aus normalen Ankerstahl.Of the Anchor can be chromed according to an advantageous embodiment. It promotes the running properties of the anchor. Alternatively, the socket in which the anchor is running, also be made as stainless steel. With similar running characteristics the anchor is then made of normal anchor steel.
Es kann zur Führung des Ankers auch zweckmäßig sein, zwei oder mehrere Ankersitze vorzusehen, mit Hilfe derer der Anker radial geführt ist.It can lead the anchor also be functional, To provide two or more anchor seats, with the help of which the anchor guided radially is.
Das Druckventil eignet sich zum Einsatz als kraft- oder lagegesteuertes Proportional-Druckventil oder Proportional-Druckbegrenzungsventil in einer Common-Rail-Kraftstoffeinspritzanlage einer Brennkraftmaschine für ein Kraftfahrzeug.The Pressure valve is suitable for use as force or position controlled Proportional-pressure valve or Proportional pressure relief valve in a common rail fuel injection system an internal combustion engine for a motor vehicle.
