Abstract

Umlaufverdrängermaschine, umfassend:
a) ein Gehäuse (3) mit einer Kammer, die einen Einlass (4) und einen Auslass (5) für ein Fluid aufweist,
b) und eine in dem Gehäuse (3) axial hin und her bewegbare Verstelleinheit mit
c) einem in der Kammer aufgenommenen Rotor (2), der zur Förderung des Fluids oder für einen Antrieb durch das Fluid um eine Drehachse (R2) drehbar gelagert ist,
d) einem Kolben (8), der einer Stirnseite des Rotors (2) axial zugewandt ist,
e) und einem in den Rotor (2) und den Kolben (8) ragenden Lagerprofil (10), das um die Drehachse (R1) eine Lagerfläche (10a) für die Drehlagerung des Rotors (2) aufweist und mit dem Kolben (8) axial fest verbunden ist,
f) wobei der Rotor (2) um die Lagerfläche (10a) oder gemeinsam mit dem Lagerprofil (10) relativ zu dem Kolben (8) drehbar ist,
dadurch gekennzeichnet, dass
g) das Lagerprofil (10) über seine zumindest nahezu gesamte axiale Länge einen der Lagerfläche (10a) entsprechenden äußeren Umfang aufweist.

Rotary displacement machine, comprising:
a) a housing (3) having a chamber which has an inlet (4) and an outlet (5) for a fluid,
b) and in the housing (3) axially reciprocable adjustment with
c) a rotor (2) accommodated in the chamber and rotatably mounted about an axis of rotation (R 2 ) for conveying the fluid or for driving it through the fluid,
d) a piston (8) which is axially facing an end face of the rotor (2),
e) and one in the rotor (2) and the piston (8) projecting bearing profile (10) around the axis of rotation (R 1 ) has a bearing surface (10a) for the rotary mounting of the rotor (2) and with the piston (8 ) is firmly connected axially,
f) wherein the rotor (2) is rotatable about the bearing surface (10a) or together with the bearing profile (10) relative to the piston (8),
characterized in that
g) the bearing profile (10) over its at least almost almost the entire axial length of the bearing surface (10 a) corresponding outer circumference.
