Description

Die bereits bekannten, zur Einführung des Brennstoffes bei Verbrennungsmotoren verwendeten Drehschieber sind in bezug auf den Zylinder und den Verbrennungsraum so angeordnet, daß die von dem Drehschieber gelieferte Brennstoffmenge unter allen Umständen in den Zylinder abgeführt werden muß, so daß eine Regelung der Brennstoffzufuhr der Belastung der Maschine entsprechend nicht ίο möglich ist.The already known, used to introduce the fuel in internal combustion engines Rotary valves are arranged in relation to the cylinder and the combustion chamber in such a way that that the amount of fuel supplied by the rotary valve must be discharged into the cylinder under all circumstances, so that a regulation of the fuel supply does not correspond to the load on the machine ίο is possible.

Dieser Übelstand wird durch den Gegenstand der Erfindung dadurch beseitigt, daß der als Einführungsorgan verwendete Drehr schieber, welcher von der Motorwelle aus in irgendeiner geeigneten Weise angetrieben wird und bei jeder Drehung die Verbindung zwischen der ölzuleitung und dem Zylinder herstellt, derart unter der Wirkung einer Feder steht, daß er wie ein Sicherheitsventil wirkt, daß einen etwaigen Drucküberschuß in einen Raum ableitet, in dem kein Druck herrscht.This drawback is eliminated by by the subject matter of the invention that produces a which is driven by the motor shaft in any suitable manner introducing member used rotation r pusher, and for each rotation of the connection between the oil supply and the cylinder, in such a manner under the action of a Spring says that it acts like a safety valve that discharges any excess pressure into a space in which there is no pressure.

Auf der Zeichnung ist eine beispielsweise Ausf ührungsform des Druckölverteilungsorgans im senkrechten Mittenschnitt dargestellt. The drawing shows an example of an embodiment of the pressure oil distribution element shown in the vertical center section.

Der als E'inführungsorgan dienende Dreh-'The rotating body serving as an introductory body

schieber α, der seinen Antrieb in geeigneter Weise, z. B. durch Mitnehmer b von einer durch den Motor angetriebenen Welle c aus erhält, ist mit einer zentrischen Bohrung d und einer exzentrischen Bohrung e versehen, die durch einen Kanal/-miteinander in Verbindung stehen. Die Bohrung d ist ständig mit der Druckölzuleitung g verbunden, während die Bohrung e bei jeder Drehung mit einer mit der nach dem Zylinder führenden Leitung h in Verbindung stehenden Bohrung i zur Deckung kommt. Der Drehschieber wird gegen. den Schieberspiegel k durch eine Feder I gedrückt, deren Stärke so bemessen ist, daß sie beim Überschreiten eines Maximal-. druckes zusammengedrückt wird und dem öl zwischen Schieber und Schieberspiegel hindurch in das den Schieber umschließende Ge- ■ häuse m zu treten gestattet, in welchem kein Druck herrscht und von wo aus es zurückgeleitet wird..slide α, which its drive in a suitable manner, z. B. obtained by driver b from a shaft c driven by the motor, is provided with a central bore d and an eccentric bore e , which are in communication with one another through a channel. The bore d is constantly connected to the pressure oil supply line g , while the bore e comes into congruence with each rotation with a bore i connected to the line h leading to the cylinder. The rotary valve is against. the slide mirror k pressed by a spring I , the strength of which is such that when a maximum is exceeded. pressure is compressed and allows the oil to pass between the slide and slide mirror into the housing m surrounding the slide, in which there is no pressure and from where it is returned.
