Abstract

The device provides and inlet or an outlet for the air-gas mixture to or from the combustion chamber. Two pipes are aligned to the top of the cylinder. The pipes comprise an inner hollow pipe, with openings located in the sleeve containing the pipe. Opening and closing of the opening at the cylinder head is achieved via rotation of the pipes about their axes.

Description

Stand der TechnikState of the art

Es ist bekannt, daß Ventile im Motor Bauteile sind, die von außen gesteuert durch Öffnen bzw. Schließen den Durchgang des Luft-Gas-Gemisches in bzw. der Abgase aus dem Zylinder regulieren. Die Steuerung des Öffnungs- bzw. Schließprozesses erfolgt durch eine Nockenwelle.It is known that valves in the engine are components controlled from the outside by opening or Closing the passage of the air-gas mixture in or regulate the exhaust gases from the cylinder. The Control of the opening or closing process done by a camshaft.

Angaben der Wirkung, die mit der Erfindung erzielt werden sollIndication of the effect with the invention should be achieved

Der im Patentanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, unnötige Energie durch Reibung (Lager der Ventile, Nockenwelle und Stösselstangen) und Verformung (Federn der Ventile) die dem Antrieb verloren gehen, zu vermeiden. The invention specified in claim 1 underlying the problem is through unnecessary energy Friction (bearings of the valves, camshaft and Push rods) and deformation (springs of the valves) to avoid being lost to the drive.  

Erreichte VorteileAchieved advantages

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin , daß durch die einfache Anordnung zweier Rohre keine aufwendige Mechanik mit energieverbrauchenden Verlustreibungen entstehen. Außerdem ist die Reparaturanfälligkeit durch die wenigen Bauteile und die einfache Art stark herabgesetzt. Ein Nachstellen der Ventile entfällt ebenfalls, da kein Verstellen der Öffnungs- bzw. Schließzeiten möglich ist. Die Erfindung ist ebenfalls erheblich kostengünstiger in der Herstellung, als die herkömmliche Ventiltechnik.The advantages achieved with the invention exist especially in that the simple Arrangement of two pipes no complex mechanics with energy-consuming loss of friction arise. It is also prone to repairs strong due to the few components and the simple nature reduced. There is no need to readjust the valves also because no adjustment of the opening or Closing times are possible. The invention is also considerably cheaper to manufacture than that conventional valve technology.

Die Erfindung betrifft das Öffnen und Schließen der im Zylinderkopf befindlichen Öffnungen bei Verbrennungsmaschinen, zum Ein- und Auslassen des Luftgasgemisches in den Zylinderraum durch ein Rohr.The invention relates to the opening and closing of the Openings located at the cylinder head Internal combustion engines, for taking in and out the Air gas mixture into the cylinder space through a pipe.

Die herkömmlichen Tellerventile besitzen einen kreisförmigen Teller, der im geschlossenen Zustand auf einem kegelstumpfförmigen Sitz aufliegt. In der Öffnungsphase ergibt sich bei dieser Ventilkonzeption infolge des ringförmigen Öffnungsspaltes ein hoher Strömungswiderstand.The conventional poppet valves have one circular plate that when closed on rests on a frustoconical seat. In the This valve concept has an opening phase due to the annular opening gap a high one Flow resistance.

Des weiteren wird für die Ventilfeder ein hoher Energieaufwand zum Öffnen benötigt, der den Wirkungsgrad herabsetzt. Diese Probleme sind durch meine Erfindung auf ein Minimum reduziert.Furthermore, a high for the valve spring Energy required to open the Efficiency reduced. These problems are over reduced my invention to a minimum.

Das Grundprinzip der Regelung des Ein- und Auslassens vom Kraftstoffgemisch bzw. der verbrauchten Abgase sind zwei um sich drehende Rohre mit versetzten länglichen Öffnungen, die im Falle der Deckungsgleichheit mit den Gängen in den Zylinderraum die Öffnung freigeben bzw. schließen (Fig. 1).The basic principle of regulating the intake and exhaust of the fuel mixture or the exhaust gases used are two rotating tubes with staggered elongated openings, which open or close the opening in the case of congruence with the gears in the cylinder chamber ( Fig. 1).

Diese Röhre besteht aus temperaturbeständigem Stahl oder Aluminium.This tube is made of temperature-resistant steel or aluminum.

Die Lagerung der Rohre ist dreifach bei einem Vierzylindermotor jeweils am Ende und einmal in der Mitte.The storage of the pipes is triple at one Four-cylinder engine at the end and once in the Center.

An einem Ende der Rohre befindet sich die Öffnung zum Vergaser bzw. zum Auspuff.The opening is at one end of the tubes to the carburetor or exhaust.

Die Schmierung zwischen der Rohre und dem Gleitschuh erfolgt durch eine Ölpumpe.The lubrication between the pipes and the Sliding shoe is done by an oil pump.
