Description

denen Charakteristiken der Schläuche 6 sowie deren Kontaktdruckes auf die Rollen 1 des Läufers.those characteristics of the hoses 6 and their contact pressure on the rollers 1 of the runner.

Der flexible Schlauch 6 weist einen in Längsrichtung konischen Querschnittsverlauf auf, d. h., der Innenquerschnitt des Schlauches 6 erweitert sich in seiner Längsrichtung in der Weise, daß die Oberfläche, auf die der Druck des Arbeitsmediums ausgeübt wird, gleichzeitig in dem Maße größer wird, wie der Druck kleiner wird, d. h., der Innenquerschnitt des Schlauches erweitert sich stetig in der Richtung des Druckabfalls. Dadurch ist bei Motorbetrieb eine totale Ausnutzung des Druckes des Arbeitsmediums und gleichfalls ein automatisches Kühlen des Schlauches auf Grund der Temperaturabsenkung bei der Expansion des Arbeitsmediums gewährleistet.The flexible hose 6 has a cross-sectional shape that is conical in the longitudinal direction, i. h., the The inner cross-section of the tube 6 widens in its longitudinal direction in such a way that the surface, on which the pressure of the working medium is exerted, increases at the same time, how the pressure gets smaller, d. That is, the inner cross-section of the hose is steadily widening in the Direction of pressure drop. This means that when the engine is running, the pressure of the Working medium and also an automatic cooling of the hose due to the temperature decrease guaranteed during the expansion of the working medium.

Bei der Arbeitsweise als Kompressor, Vakuummaschine oder Pumpe wird der Läufer über den in F i g. 1 schematisch dargestellten Hilfsmotor 5 in der Richtung der Pfeile angetrieben. Durch die periodische Verformung jedes Volumenabschnittes des Schlauches 6 zwischen zwei Rollen 1 wird das Medium aufeinanderfolgend angesaugt und in der Weise ίο komprimiert, daß es unter Druck zu einem Sammelbehälter oder in die Atmosphäre evakuiert wird. Im Falle eines Pumpbetriebs tritt die Pumpwirkung sofort ein, wobei die Drehgeschwindigkeit gering sein kann.When working as a compressor, vacuum machine or pump, the rotor is operated via the in F i g. 1 shown schematically auxiliary motor 5 driven in the direction of the arrows. Through the periodic Deformation of each volume section of the hose 6 between two rollers 1 becomes the medium successively sucked in and compressed in such a way that it is under pressure to a collecting container or evacuated to the atmosphere. In the case of a pumping operation, the pumping effect occurs immediately the speed of rotation may be slow.
