Abstract
Vorgeschlagen ist ein Steuerventil für einen Nockenwellenversteller einer Hubkolbenbrennkraftmaschine, das mit Druckmittel beaufschlagbare Arbeitskammern beherrscht, mit einem Zentralgehäuse (1), das Arbeitskammeranschlüsse und einen Druckanschluss aufweist und mit einem beweglich geführten Steuerkolben (7) versehen ist, wobei der Steuerkolben (7) einerseits von einer Feder (8) belastet ist und andererseits mittels eines Kolbenkopfes (9) mit einer maschinenfest angeordneten Betätigungseinheit in Wirkverbindung steht, hohl ausgeführt ist und Außenstege (4 bis 6) aufweist und wobei ein Zusatzkolben (11) vorgesehen ist, der eine Kolbenverlängerung (13) aufweist, die durch eine Öffnung im Kolbenkopf (9) des Steuerkolbens (7) mit der Betätigungseinheit verbindbar ist.Proposed is a control valve for a camshaft adjuster of a reciprocating internal combustion engine, which dominates pressurizable working chambers, with a central housing (1), the working chamber connections and a pressure connection and is provided with a movably guided control piston (7), wherein the control piston (7) on the one hand a spring (8) is loaded and on the other hand by means of a piston head (9) with a machine fixedly arranged actuating unit is operatively connected, hollow and outer webs (4 to 6) and wherein an additional piston (11) is provided, which is a piston extension (13 ), which is connectable through an opening in the piston head (9) of the control piston (7) with the actuating unit.
Description
Die Erfindung bezieht sich auf ein Steuerventil für einen Nockenwellenversteller einer Hubkolbenbrennkraftmaschine, das mit Druckmittel beaufschlagbare Arbeitskammern beherrscht, mit einem Zentralgehäuse, das Arbeitskammeranschlüsse und einen Druckanschluss aufweist und mit einem beweglich geführten Steuerkolben versehen ist, wobei der Steuerkolben einerseits von einer Feder belastet ist und andererseits mittels eines Kolbenkopfes mit einer maschinenfest angeordneten Betätigungseinheit in Wirkverbindung steht, hohl ausgeführt ist und Außenstege aufweist. The invention relates to a control valve for a camshaft adjuster a reciprocating internal combustion engine, which dominates pressurizable working chambers, with a central housing, the working chamber connections and a pressure port and is provided with a movably guided control piston, wherein the control piston is loaded on the one hand by a spring and on the other is operatively connected by means of a piston head with a machine fixedly arranged actuator unit, is hollow and has outer webs.
Derartige Steuerventile von Nockenwellenverstellern sind allgemein bekannt. Das Steuerventil der
Aufgabe der Erfindung ist es, das bekannte Steuerventil derart zu verbessern, dass die angesprochenen Nachteile behoben werden und weitere Steuermöglichkeiten zur Verfügung stehen. Dies soll mit einfachen, kostengünstigen Mitteln erfolgen.The object of the invention is to improve the known control valve such that the disadvantages mentioned are eliminated and further control options are available. This should be done with simple, inexpensive means.
Erfindungsgemäß wird die Aufgabe durch einen Zusatzkolben gelöst, der eine Kolbenverlängerung aufweist, die durch eine Öffnung im Kolbenkopf des Steuerkolbens mit der Betätigungseinheit verbindbar ist. Die Kolbenverlängerung kann mit dem Kolbenkopf in Richtung der Betätigungseinheit plan abschließen, wobei die Betätigungseinheit dann vorzugsweise zwei Betätigungsstifte aufweist, die getrennt mit dem Kolbenkopf und der Kolbenverlängerung in Wirkverbindung stehen, so dass beide Kolben beliebig angesteuert werden können. Die Kolbenverlängerung kann aber auch aus dem Kolbenkopf herausragen, so dass auch bei nur einem Betätigungsstift der Betätigungseinheit zuerst der Zusatzkolben und dann der Steuerkolben betätigt werden.According to the invention the object is achieved by an additional piston having a piston extension which is connectable through an opening in the piston head of the control piston with the actuating unit. The piston extension can end flush with the piston head in the direction of the actuating unit, wherein the actuating unit then preferably has two actuating pins, which are separately in operative connection with the piston head and the piston extension, so that both pistons can be controlled as desired. But the piston extension can also protrude from the piston head, so that even with only one actuating pin of the actuating unit, the auxiliary piston and then the control piston are actuated first.
Der Zusatzkolben kann innerhalb des Steuerkolbens oder axial vor bzw. hinter dem Steuerkolbens eingebaut sein. Ist der Zusatzkolben innerhalb des Steuerkolbens angeordnet, so kann der Zusatzkolben frei im Steuerkolben beweglich angeordnet sein. Vorzugsweise ist der Zusatzkolben mittels einer Zusatzfeder axial belastet, so dass er unabhängig vom Steuerkolben nur von der Zusatzfeder und der Betätigungseinheit geführt ist.The auxiliary piston can be installed inside the control piston or axially in front of or behind the control piston. If the additional piston is arranged inside the control piston, then the additional piston can be arranged to be freely movable in the control piston. Preferably, the auxiliary piston is axially loaded by means of an additional spring, so that it is guided independently of the control piston only by the auxiliary spring and the actuating unit.
