Description

Vorrichtung zum geräuschlosen Steuern von Ventilen an Verbrennungsmotoren. Es ist bekannt geworden, die Ventile von Verbrennungsmotoren u. :dgl. durch eine Druckflüssigkeit, die von einem Pumpwerk bewegt wird, zu steuern.Device for the noiseless control of valves on internal combustion engines. It has become known that the valves of internal combustion engines and the like. by a To control hydraulic fluid that is moved by a pumping station.

Sofern indessen nur ein Pumpwerk eine größere Anzahl von Ventilen mit zeitlich verschiedenem Hub bedienen soll, kann dies in bekannter Weise und unter Zuhilfenahme von Druckverteilern, welche gleich der Anzahl der Ventile sind, geschehen.If, however, only one pumping station has a larger number of valves to operate with a different stroke in time, this can be done in a known manner and under With the help of pressure distributors, which are equal to the number of valves, happen.

Die Erfindung besteht demgegenüber darin, daß eine mit mehreren Kammern versehene Pumpe mit umlaufendem Kolben sämtliche Ventile einer Verbrennungskraftmaschine in an sich bekannter Weise durch ein Druckmittel steuert, das auf beide Seiten der Ventilkolben einwirkt.The invention consists in the fact that one with several chambers equipped pump with rotating piston all valves of an internal combustion engine controls in a known manner by a pressure medium on both sides of the Acts valve piston.

In der Zeichnung ist der Erfindungsgegenstand beispielsweise dargestellt, und zwar zeigt Abb. z eine Schnittansicht des Gehäuses nach Linie A-B der Abb. z, Abb. a einen Querschnitt hierzu, Abb. 3 eine Abwicklung, Abb. 4 ein Schema der Gesamtanordnung. In einem feststehenden, allseitig geschlossenen Gehäuse a von zylindrisch - ringförmiger Gestalt dreht sich. um, die Mittelachse ein Körper b mit einem in sich zurücklaufenden Steg c, der im Gehäuse a zwei gleich große Kammern schafft. Das Ringgehäuse ist durch radiale, jedoch achsial verschiebbare Schieber d j e nach Anzahl der zu betätigenden Ventile beispielsweise in, sechs Kammern eingeteilt, welche keine Verbindung miteinander haben. Von jeder Kammer führen zwei Rohrleitungen e und e1. zu Ventilzylindern f und münden unter- und oberhalb des Ventilkolbens g. Die Kammern im Ringgehäuse a sowie die Rohrleitungen e und el wie auch der freie Raum in den Ventilzylindern (sind mit einer Flüssigkeit, beispielsweise öl, angefüllt.In the drawing, the subject matter of the invention is shown, for example, namely Fig. z shows a sectional view of the housing along line A-B of Fig. z, Fig. A shows a cross-section of this, Fig. 3 shows a development, Fig. 4 shows a diagram of the overall arrangement. In a stationary, all-round closed housing a of cylindrical - ring-shaped Shape rotates. um, the central axis a body b with a receding in itself Bar c, which creates two chambers of the same size in housing a. The ring case is by radial, but axially displaceable slides d j e according to the number of actuators Valves, for example, divided into six chambers, which do not communicate with one another to have. Two pipes e and e1 lead from each chamber. to valve cylinders f and open below and above the valve piston g. The chambers in the ring housing a as well as the pipes e and el as well as the free space in the valve cylinders (are filled with a liquid, e.g. oil.

Beim Umlauf des Körpers b wird durch den Steg c die in den Kammern befindliche Flüssigkeit von der einen nach der anderen Seite gegen die Gehäusewandung gedrückt, die ihren Raumausgleich in den Rohrleitungen e und e1 und den Ventilzylindern f findet, wobei eine entsprechende Verlagerung der Ventilkolben g und der Ventilkegel e folgen muß, also daß letztere geöffnet und geschlossen werden. Die Spiralfeder h bewirkt eine Voreilung auf Schließstellung gegenüber der Offenstellung der Ventilkegel i. Die konstruktive Form des Steges c bestimmt die Dauer der Schließstellung und der Offenstellung der Ventilkegel i. Die Schieber d haben nur die Aufgabe, die einzelnen Kammern voneinander zu trennen, demgemäß haben die Ausgleichkanäle k nur den Zweck, die Flüssigkeit, mit welcher alle Hohlräume innerhalb des Gehäuses a ausgefüllt sind, bei einer Bewegung des Schiebers d von der einen zur anderen gegenüberliegenden Seite umzuleiten. Durch das Anfüllen aller hohlen Räume des Gehäuses a mit Flüssigkeit wird der Druckverlust bei Undichtigkeiten bei den Schiebern d äußerst gering bleiben.When the body b circulates, the liquid in the chambers is pressed from one side to the other against the housing wall through the web c, which finds its space compensation in the pipelines e and e1 and the valve cylinders f, with a corresponding displacement of the valve piston g and the valve cone e must follow, so that the latter are opened and closed. The spiral spring h causes an advance to the closed position compared to the open position of the valve cone i. The structural shape of the web c determines the duration of the closed position and the open position of the valve cone i. The sliders d only have the task of separating the individual chambers from each other, accordingly the compensating channels k only have the purpose of the liquid with which all cavities within the housing a are filled when the slider d moves from one to the other opposite Redirect page. By filling all the hollow spaces of the housing a with liquid, the pressure loss in the event of leaks in the slides d will remain extremely low.
