摘要： A pump having a rotor that is rotatable about a rotation axis and comprises a rotor hub and a rotor collar that extends from the rotor hub in the radial direction and encircles it in an undulating manner, and a pump housing which comprises a first axial housing component, a central annular housing component and a second axial housing component, wherein a pump duct is formed in the axial direction by the first and second housing components and in the radial direction by the central annular housing component and the rotor, and also a pump in which the annular pump duct has a constant cross section and connects a first radially external inlet/outlet space to a second radially external inlet/outlet space, and the pump may include a blocking device which is arranged between the first radially external inlet/outlet space and the second radially external inlet/outlet space and which comprises a blocking element which blocks the pump duct in the axial direction on both sides of the rotor collar.

摘要： Eine Pumpe (10) umfasst:
wenigstens einen um eine Drehachse drehbaren Rotor (12),
ein Pumpengehäuse (14), das den Rotor (12) umgibt, wobei ein Pumpenkanal (18) zwischen einer radial innen liegenden Oberfläche des Pumpengehäuses (14) und einer radial außen liegenden Oberfläche des Rotors (12) gebildet ist, und
eine Dichtanordnung (100), welche den Pumpenkanal (18) an einer Endfläche des Rotors (12) abdichtet, wobei die Dichtanordnung (100) umfasst:
eine Gleitfläche, welche an einem Element aus dem Rotor (12) und dem Pumpengehäuse vorgesehen ist und welche sich senkrecht zur Achsrichtung des Rotors (12) erstreckt;
eine statische Fläche, welche an dem jeweils anderen Element aus dem Rotor (12) und dem Pumpengehäuse (14) vorgesehen ist; und
ein erstes Elastomerelement, das an der statischen Fläche angebracht ist und in axialer Richtung gegen die Gleitfläche gedrückt wird.

摘要： A pump having a rotor that is rotatable about a rotation axis and comprises a rotor hub and a rotor collar that extends from the rotor hub in the radial direction and encircles it in an undulating manner, a pump housing which forms a pump duct with the rotor, said pump duct connecting a first inlet/outlet space to a second inlet/outlet space and a blocking device which is arranged between the first inlet/outlet space and the second inlet/outlet space and which comprises a blocking element which blocks the pump duct in the axial direction on both sides of the rotor collar. The blocking device has a first seat and a second seat for the blocking element, wherein the spacing between the first seat and the second seat in the circumferential direction is greater than the spacing between a first contacting face and a second contacting face of the blocking element in the circumferential direction. The invention also relates to a pump having a blocking device which includes a chamber formed in the pump housing, wherein the chamber and the blocking element are configured such that an exchange duct is formed in the axial direction between an axially front fluid chamber and an axially rear fluid chamber on the opposite side of the rotor collar, and to a corresponding blocking element.
