Description
Gebiet der ErfindungField of the invention
Die gegenwärtige Erfindung betrifft eine Vorrichtung zur Ansteuerung von mindestens einem Motorventil. Im Besonderen ist bei der Vorrichtung zur Ansteuerung von mindestens einem Motorventil ein Fluidreservoir vorgesehen. Das Fluidreservoir ist mit einer Pumpe verbunden, die zur Erzeugung eines Drucks in einem aus dem Fluidreservoir entnommenen Fluid dient. Der von der Pumpe erzeugte Druck wird in einem Hochdruckraum gespeichert, um den dort gespeicherten Druck später für die Beaufschlagung des mindestens einen Motorventils zu verwenden.The The present invention relates to a device for driving of at least one engine valve. In particular, in the device for controlling at least one engine valve, a fluid reservoir intended. The fluid reservoir is connected to a pump which for generating a pressure in a withdrawn from the fluid reservoir Fluid is used. The pressure generated by the pump is in a high pressure chamber saved to the stored there pressure later for to use the application of the at least one engine valve.

Aufgabe der gegenwärtigen Erfindung ist, eine Vorrichtung zu schaffen, mit der der für eine hydraulische Ventilsteuerung erforderliche Druck mit einem geringeren Energieverbrauch erzeugt werden kann.task the present invention is to provide a device with the required for a hydraulic valve control Pressure can be generated with a lower energy consumption.
Die obige Aufgabe wird gelöst durch eine Vorrichtung, die die Merkmale des Anspruchs 1 umfasst.The The above object is achieved by a device that the Features of claim 1 comprises.
Es ist dabei von Vorteil, wenn die Vorrichtung zur Ansteuerung von mindestens einem Motorventil mit einem Fluidreservoir verbunden ist. Ferner ist eine Pumpe vorgesehen, die zur Erzeugung eines Drucks in einem aus dem Fluidreservoir entnommenen Fluid dient. Der mit der Pumpe erzeugte Druck wird zur Speicherung in einen Hochdruckraum überführt. Der erzeugte Druck wird zur Beaufschlagung von mindestens einem Motorventil verwendet. Die zur Erzeugung verwendete Pumpe ist eine Resonanzpumpe.It is advantageous if the device for controlling at least one engine valve is connected to a fluid reservoir. Furthermore, a pump is provided which serves to generate a pressure in a fluid withdrawn from the fluid reservoir. The pressure generated by the pump is transferred to a high-pressure chamber for storage. The pressure generated is used to pressurize at least one engine valve. The pump used for the production is a resonance pump.
Jeden der Motorventile ist mindestens ein steuerbares Ventil vorgeschaltet, das die Druckbeaufschlagung und Druckabführung eines Ventilkolbens des Motorventils zur Verfügung stellt. So kann z. B. jedem Motorventil ein einziges steuerbares Ventil zugeordnet sein, das als ein 3/3-Wege-Ventil ausgebildet ist. Ebenso ist es möglich, dass jedem Motorventil zwei steuerbare Ventile vorgeschaltet sind, die jeweils als 2/2-Wege-Ventile ausgestaltet sind.each the engine valves are preceded by at least one controllable valve, the pressurization and pressure discharge of a valve piston the engine valve provides. So z. B. everyone Engine valve to be assigned a single controllable valve, the is designed as a 3/3-way valve. It is also possible that each engine valve two controllable valves are connected upstream, the are each designed as 2/2-way valves.
Das verwendete Fluid ist ein nicht kompressibles Hydraulikmedium. In einer bevorzugten Ausführungsform ist das nicht kompressible Hydraulikmedium ein Öl.The used fluid is a non-compressible hydraulic medium. In In a preferred embodiment, this is not compressible Hydraulic medium an oil.
Der Hochdruckraum versorgt alle Motorventile mit einem entsprechenden Druck. Dabei ist jedes Motorventil federbeaufschlagt, um das jeweilige Motorventil nach der Druckabführung durch das zugeordnet steuerbare Ventil in den geschlossenen Zustand überzuführen.Of the High-pressure chamber supplies all engine valves with a corresponding one Print. Each motor valve is spring loaded to the respective Motor valve assigned to the pressure dissipation by the to transfer controllable valve in the closed state.
Eine Unwucht treibt die Resonanzpumpe an. Die Unwucht wird durch einen Exzenter erzeugt, der durch einen Elektromotor angetrieben wird.A Imbalance drives the resonance pump. The imbalance is caused by a Generated eccentric, which is driven by an electric motor.
Der gespeicherte Druck aus dem Hochdruckraum wird durch das mindestens eine steuerbare Ventil in und aus einem Ventilanbindungsraum geleitet.Of the stored pressure from the high-pressure chamber is through the at least a controllable valve in and out of a valve connection space.
An das mindestens eine steuerbare Ventil schließt sich ein Niederdruckraum an, der den vom Motorventil abgeführten Druck aufnimmt. Der Niederdruckraum kann dabei mit dem Eingang der Pumpe verbunden sein.At the at least one controllable valve closes Low pressure chamber on, the discharged from the engine valve Pressure picks up. The low-pressure chamber can with the entrance of the Be connected pump.
Im Folgenden sollen Ausführungsbeispiele die Erfindung und ihre Vorteile anhand der beigefügten Figuren näher erläutern.in the Below are embodiments of the invention and their advantages with reference to the accompanying figures closer explain.
