Abstract

Receiver is designed to smooth out the peak pressures in an internal combustion engine, returning a gases to the combustion chamber after the peaks. It operates at a pressure above that of the engine compression pressure, and can be actuated by mechanical or air spring. Stored pressure from receiver vessel is returned to the combustion chamber at an equalised pressure, which results in reduced noise, compression losses and heating pressures.

Titel:Title:

DruckspeicherPressure accumulator

Anwendungsgebiet :Field of use :

Die Erfindung hat die Aufgabe die Druckspitze , bei der Verbrennung in Verbrennungsmotoren, zu speichern. Der gespeicherte Druck wird nach der Verbrennung wieder gleichmäßig in den Brennraum gedruckt.The invention has the task of reducing the pressure peak during combustion in internal combustion engines, save. The stored pressure becomes uniform again after the combustion printed in the combustion chamber.

Stand der
Technik:State of
Technology:

Bei den bekannten Verbrennungsmotoren findet die Verbrennung in einem unnachgiebigen Raum statt, wenn man das kraftausnutzende Teil nicht berücksichtigt. Im Moment der Verbrennung tritt eine hohe Druckspitze ein, die nicht sofort in Arbeit umgesetzt werden kann. Es entstehen mit der Druckspitze hohe Temperaturen, große Lagerdrücke und die Dichtelemente werden stark belastet. In der Druckspitze entsteht somit unnötiger Verschleiß und außerdem geht Arbeitsdruck verloren. In the known internal combustion engines, the combustion takes place in an unyielding space instead of not considering the force-utilizing part. The moment the burn occurs a high pressure peak that cannot be put into work immediately. It arise with the pressure peak high temperatures, high bearing pressures and the sealing elements are heavily loaded. This creates unnecessary wear in the pressure peak and also loses working pressure.

Aufgabe: Der Erfindung liegt die Aufgabe zugrunde, die Lebensdauer und den Wirkungsgrad von Verbrennungsmotoren zu erhöhen.Task: The invention is based on the task of increasing the service life and the efficiency of internal combustion engines to increase.

Erzielbare
Vorteile :Achievable
Advantages :

Die mit der Erfindung erzielbaren Vorteile werden durch die Speicherung der Druckspitze. bei der Verbrennung und deren Rückgabe.erreicht. •°ei einer geringeren Druckspitze verringern sich die Verbrennungsgeräusche, der Kompressionsverlust und die Lagerdrücke. Der langer anhaltende Druck erzeugt einen besseren Wirkungsgrad.The advantages that can be achieved with the invention are achieved by storing the pressure peak. during the incineration and their return. • A lower pressure peak reduces combustion noise, compression loss and bearing pressures. The long lasting one Pressure creates better efficiency.

Beschreibung:Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Der Druckspeicher ist so mit dem Verbrennungsraum verbunden, daß er die Verdichtung nicht verändert. Die Anbringung kann am Verbrennungsraum (unbeweglich) oder im Arbeitsteil (beweglich) angebracht sein.Description: An embodiment of the invention is shown in Drawing shown and is described in more detail below. The accumulator is like that with that Combustion chamber connected so that it does not change the compression. It can be attached to the combustion chamber (immobile) or in the working part (movable).

Der Druckspeicher ist wie folgt aufgebaut: Er besteht aus einem Zylinder 2 und dem Zylinderdeckel 1, die zur oberen Seite einen geschlossenen Raum bilden. Der Kolben 3 befindet sich auf der unteren Seite des Raumes und wird durch die Schraubendruckfeder 5 an die Anlaufkante gedrückt. Bei der Aufwärt sbewegung des Kolben wird außer der 3chraubendruckfeder 5 im Druckraum 6 eine zusätzliche Z^ederwirkung mit der Kompression erzielt. Die Arbeitsweise ist wie folgt: Der Anpreßdruck der Schi^aubendruckf eder 5 liegt über dem Verdichtungsdruck des Motors,■so daß die Verbrennung nicht beeinflußt wird. Der über die Federspannung steigende- Druck weicht zunächst durch das Anheben des Kolbens 3 in den Zylinder 2 aus. Es wird damit eine hohe Druckspitze vermieden und der gespeicherte Druck gelangt bei Druckabfall wieder in den Verbrennungsraum zurück.The pressure accumulator is constructed as follows: It consists of a cylinder 2 and the cylinder cover 1, which form a closed space on the upper side. The piston 3 is located on the lower side of the room and is pressed against the leading edge by the helical compression spring 5. In the upward- the piston sbewegung is achieved except for the 3chraubendruckfeder 5 i m-pressure chamber 6, an additional Z ^ Eder effectively with the compression. The mode of operation is as follows: The contact pressure of the slip pressure spring 5 is above the compression pressure of the engine, so that the combustion is not influenced. The pressure that rises via the spring tension initially gives way to the cylinder 2 by lifting the piston 3. This avoids a high pressure peak and the stored pressure returns to the combustion chamber in the event of a pressure drop.
