Abstract

The piston assembly with a stroke movement, and especially for the pumping of a gas medium by drawing it in and pushing it out, has at least one cylinder (5) for a moving piston. The piston is coupled (2) to a crank or eccentric (1) for the drive, and which rotates in a given direction and rotary speed and especially a resonant rotary speed. The drive transmission between the eccentric and the piston (4) is through an elastic spring (3).

Description

Die Erfindung betrifft eine Hubkolbenmaschine, insbesondere ein Verdrängeraggregat mit wenigstens einem Zylinder und darin verschieblich angeordnetem Kolben, der vor allem ein gasförmiges Medium einerseits ansaugt und andererseits ausstößt. The invention relates to a reciprocating piston machine, in particular a Displacement unit with at least one cylinder and displaceable therein arranged piston which primarily sucks a gaseous medium on the one hand and on the other hand ejects.

Derartige Maschinen sind bekannt; z. B. sogenannte ROOTS-Gebläse oder ähnliche Verdrängermaschinen. Diese dienen vornehmlich zum Transport bzw. (leichtem) Verdichten von gasförmigen Medien. Such machines are known; z. B. so-called ROOTS blowers or the like Displacement machines. These are primarily used for transport or (light) Compression of gaseous media.

Zur Überwindung aller beim Betreiben dieser Maschinen auftretenden Widerstände ist bekanntlich eine bestimmte Antriebsleistung erforderlich. To overcome all resistances that occur when operating these machines a certain drive power is known to be required.

Ziel der Erfindung ist die Minimierung dieser Antriebsleistung. Die Lösung dieser Aufgabenstellung wird nachfolgend und in den Patentansprüchen beschrieben; außerdem findet die Erklärung anhand von Fig. 1 statt. The aim of the invention is to minimize this drive power. The solution to this problem is described below and in the claims; in addition, the explanation takes place with reference to FIG. 1.

In Fig. 1 ist mit 1 eine Kurbel bzw. ein Exzenter bezeichnet, welcher mit einer bestimmten Drehrichtung und Drehzahl - insbesondere Resonanzdrehzahl - rotiert. Mit 2 ist ein Koppelelement bezeichnet, welches z. B. als Pleuel ausgebildet sein kann. Mit 3 ist ein elastisches Element gekennzeichnet, insbesondere Federbauteil. In Verbindung mit den existierenden Massen ensteht damit ein sogenanntes Feder- Masse-System, welches schwingfähig ist und insbesondere eine sogenannte Eigenkreisfrequenz (Resonanz) aufweist. In Fig. 1, 1 denotes a crank or an eccentric which rotates with a certain direction of rotation and speed - in particular resonance speed. With 2 a coupling element is designated, which, for. B. can be designed as a connecting rod. 3 is an elastic element, in particular spring component. In connection with the existing masses, a so-called spring-mass system is created, which is oscillatable and in particular has a so-called natural angular frequency (resonance).

Arbeitet die gezeigte Maschine insbesondere als Gastransportaggregat und mit der Eigenkreisfrequenz, dann vergrößert sich der Kolbenhub von dem ursprünglichen Exzenterhub auf den wesentlich größeren Resonanzhub, ohne dabei mehr Antriebsleistung zu benötigen. Mit anderen Worten: Bei gleichem Transportvolumen kann die erforderliche Antriebsleistung gegenüber konventionellen Maschinen z. B. um den Faktor 4 verringert werden, das anvisierte Ziel der Aufgabenstellung also mit recht einfachen Mitteln erreicht werden. The machine shown works in particular as a gas transport unit and with the Natural angular frequency, then the piston stroke increases from the original Eccentric stroke to the much larger resonance stroke, without doing more Need drive power. In other words: with the same transport volume can the required drive power compared to conventional machines such. B. be reduced by a factor of 4, i.e. the target of the task can be achieved with very simple means.

In Fig. 1 ist weiterhin mit 4 der mit 3 kraftschlüssig in Verbindung stehende Kolben gekennzeichnet. Letzterer läuft, wie bereits bekannt, in einem Zylinder 5, welcher im Zylinderkopf das Saugventil 6 und das Druckventil 7 aufweist. Letztere öffnen bzw. schließen selbsttätig bei entsprechendem Unter- bzw. Überdruck. In Fig. 1, the piston with 3 non-positively connected piston is also identified with 4 . As already known, the latter runs in a cylinder 5 which has the suction valve 6 and the pressure valve 7 in the cylinder head. The latter open or close automatically with a corresponding negative or positive pressure.

Im Ergebnis ist erfindungsgemäßes Aggregat einfach im Aufbau, kostengünstig in der Fertigung und effektiv in seiner Wirkung. Es lässt sich überall dort sehr wirtschaftlich betreiben, wo gasförmige Medien transportiert bzw. leicht verdichtet werden müssen. As a result, the unit according to the invention is simple in construction, inexpensive in the manufacture and effective in its effect. You can do it everywhere operate economically where gaseous media is transported or easily compressed Need to become.
