Description

Drehkolbenkraftmaschine, -pumpe oder -verdichter mit exzentrisch zum Gehäuse gelagerter Kolbentrommel Drehkolbenmaschinen mit exzentrisch zum Gehäuse angeordneter Kolbentrommel mit einer für die Drehkolben bestimmten, durchgehenden Bohrung sind bereits bekannt. Bei diesen bekannten Maschinen ist auch eine konzentrisch zum Gehäuse und exzentrisch zur Kolbentrommel gelagerte *und mit dem der Antriebshelle gegenüberliegenden Gehäuseteil fest verbundene Steuerungswelle vorgesehen, welche in eine für sie vorgesehene Aussparung der Kolbentrommel eingreift. Die Kolben sind kreisrund, und ihr Durchmesser ist genau so groß wie die Länge der Arbeitskammern, in axialer Richtung gemessen. Die zylindrischen Kolben haben dadurch mit den Stirnwänden des Gehäuses nur Liniendichtung, die nicht einwandfrei ist. Auch besitzen die Kolben an ihrer Stirnseite keine drehbaren, im 'Querschnitt im wesentlichen halbkreisförmigen Dichtungsleisten. Die Abdichtungsverhältnisse sind also nicht sehr günstig. Es sind wohl auch Maschinen mit drehbaren Dichtungsleisten bekannt, deren beide Drehkolben aber durch Kurbeltriebe miteinander verbunden sind und rechteckigen, nicht kreisförmigen Querschnitt haben.Rotary piston engine, pump or compressor with eccentric to Housing mounted piston drum rotary piston machines with eccentric to the housing arranged piston drum with a intended for the rotary piston, through Boreholes are already known. In these known machines, one is also concentric to the housing and eccentrically to the piston drum * and with that of the drive shell opposite housing part firmly connected control shaft provided which engages in a recess provided for them in the piston drum. The pistons are circular, and their diameter is exactly the same as the length of the working chambers, measured in the axial direction. The cylindrical pistons have thereby with the end walls of the housing only a line seal, which is not perfect. Also own the pistons on their end face no rotatable, essentially semicircular in cross-section Sealing strips. The sealing conditions are therefore not very favorable. There are probably also known machines with rotatable sealing strips, both of which have rotary pistons but connected by crank mechanisms and are rectangular, not circular Have cross-section.

Erfindungsgemäß sind die Drehkolben an ihrer Stirnseite mit drehbaren, im Querschnitt irii wesentlichen halbkreisförmigen Dichtungsleisten und an ihrem Fuße zwecks Führung durch die Steuerungswelle mit entsprechend gekrümmten Steuerungsflächen versehen. Der Durchmesser .der Drehkolben ist etwas größer als die Länge des Gehäusehohlraumes, und zwecks Anpassung an die Länge des Gehäusehohlraumes und zur Bildung von Seitenflächen, die abdichtend wirken, sind je zwei diametral gegenüberliegende, parallel zu den Gehäusestirnwänden verlaufende Segmentstücke von den Drehkolben entfernt.According to the invention, the rotary pistons are equipped with rotatable, in cross section irii essentially semicircular sealing strips and on their Feet for the purpose of guiding through the control shaft with correspondingly curved control surfaces Mistake. The diameter of the rotary piston is slightly larger than the length of the housing cavity, and for the purpose of adaptation to the length of the housing cavity and to form side surfaces, which have a sealing effect are each two diametrically opposite, parallel to the Housing end walls extending segment pieces removed from the rotary piston.

Die Maschine besitzt ein Gehäuse i. In diesem Gehäuse i ist eine exzentrisch gelagerte Kolbentrommel z .eingelassen, die in der Mitte eine :durchgehende Bohrung 3 hat, deren Durchmesser größer als die Länge des Gehäusehohlraumes z i ist.The machine has a housing i. In this housing i one is eccentric bearing-mounted piston drum, for example, let in, the one in the middle a: 3, the diameter of which is greater than the length of the housing cavity z i.

An der einen Seite der Kolb.entrommel2 befindet sich eine Steuerungsaussparung 4, an der anderen Seite die Antriebswelle 5. In der r Kolbentrommelbohrung 3 bewegen sich zwei Drehkolben 6 und ; , die am Kopfe drehbare, im Querschnitt im wesentlichen halbkreisförmige Dichtungsleisten 3 und 9 haben, auf und nieder. Am Fuße haben die Drehkolben 6 und 7 gekrümmte Steuerungsflächen i i und 12, welche auf der Steuerungswelle i o, die zentrisch zur Gehäusewand und exzentrisch zur Kolbentrommel 2 fest gelabert ist und durch die für sie bestimmte kreisrunde Aussparung 4. in der Kolbentrommel 2 führt, abrollen und somit zusammen mit den Dichtungsleisten 8 und 9 zwangsläufig gesteuert werden.Is located at one side of the control Kolb.entrommel2 a recess 4 on the other side of the drive shaft 5. In the piston drum r bore 3 to move two rotary pistons 6 and; , which have rotatable, in cross-section essentially semicircular sealing strips 3 and 9, up and down. At the foot of the rotary pistons 6 and 7 have curved control surfaces ii and 12, which roll and roll on the control shaft io, which is fixed centrically to the housing wall and eccentrically to the piston drum 2 and through the circular recess 4 intended for them in the piston drum 2 thus inevitably controlled together with the sealing strips 8 and 9.

Der Durchmesser der Drehkolben 6 und ; ist etwas größer als die Länge des Gehäusehohlraumes 2 1, weshalb zur Bildung von Seitenflächen 13, 14, 15 und 16 je zwei diametral gegenüberliegende, parallel zu den Gehäusestirnwänden verlaufende Segmentstücke von den Drehkolben entfernt sind und dadurch mit den Seitenflächen 17, 18, i9 und 2o der Dichtungsleisten 8 und 9 im Gehäuse i abdichtend wirken.The diameter of the rotary piston 6 and; is slightly larger than the length of the housing cavity 2 1, which is why to form side surfaces 13, 14, 15 and 16 each two diametrically opposite, parallel to the housing end walls Segment pieces are removed from the rotary piston and thereby with the side surfaces 17, 18, i9 and 2o of the sealing strips 8 and 9 act in a sealing manner in the housing i.

Bei Drehung der Kolbentrommel 2 im Gehäuse i dichten sich die beiden Drehkolben 6 und 7 durch ihre zylindrische Form unterhalb der Seitenflächen 13, 14, 15 und 16 gegenseitig in der Kolbentrommel 2 ab und bilden durch ihre durch die Steuerungswelle io bewirkte zwangsläufige Steuerung die Arbeitskammern.When the piston drum 2 rotates in the housing i, the two seal one another Rotary pistons 6 and 7 due to their cylindrical shape below the side surfaces 13, 14, 15 and 16 from each other in the piston drum 2 and form through their the control shaft io brought about positive control of the working chambers.

Als Verbrennungskraftmaschine in Verbin- -dung mit einem Verdichter derselben Bauart erzielt die ilIaschine einen hohen Verdichtungsdruck. Dadurch ergibt sich eine erhöhte Brennstoffausnutzung und durch das restlose Ausspülen der Gase eignet sich die Maschine für alle Brennstoffarten, besonders für Holzgas mit seinen verschmutzenden Teerbestandteilen.As an internal combustion engine in connection with a compressor of the same design, the ilI machine achieves a high compression pressure. This results in increased fuel efficiency and the complete flushing of the gases the machine is suitable for all types of fuel, especially wood gas with its polluting tar constituents.
