Title (EN) POSITIVE-DISPLACEMENT MACHINE
(FR) MACHINE VOLUMÉTRIQUE
(DE) VERDRÄNGERMASCHINE
Abstract:
(EN) The invention relates to a positive-displacement machine (40) comprising an inlet region (27) via which a working medium flows into at least one positive-displacement chamber (29, 30) of the positive-displacement machine (40). In order to create a positive-displacement machine which can be operated without any problem using low-viscosity media such as ORC fluids, at least one flow conducting device (31) which optimizes the inlet region (27) in terms of the flow behavior is placed in the inlet region (27).
(FR) L'invention concerne une machine volumétrique (40) comprenant une zone de flux entrant (27) par l'intermédiaire de laquelle un milieu de travail afflue dans au moins un espace volumétrique (29, 30) de la machine volumétrique (40). L'invention vise à créer une machine volumétrique qui peut fonctionner sans problème avec des milieux à faible viscosité tels que des fluides ORC. Au moins un dispositif conducteur de flux (31) est disposé à cet effet dans la zone de flux entrant (27) et permet d'optimiser selon la technique des fluides la zone de flux entrant (27).
(DE) Die Erfindung betrifft eine Verdrängermaschine (40) mit einem Einströmbereich (27), über den ein Arbeitsmedium in mindestens einen Verdrängerraum (29,30) der Verdrängermaschine (40) einströmt. Um eine Verdrängermaschine zu schaffen, die mit niedrig viskosen Medien, wie ORC-Fluiden, problemlos betrieben werden kann, ist in dem Einströmbereich (27) mindestenseine Strömungsleiteinrichtung (31) angeordnet, durch welche der Einströmbereich (27) strömungstechnisch optimiert wird.
