Abstract

Pumpe, umfassend ein Aufnahmegehäuse (20), welches einen topfförmigen Aufnahmeraum (25) mit einer Stirnwand (20c) und einer Umfangswand (20d) bildet, einen Pumpeneinsatz (1), der in dem Aufnahmeraum (25) angeordnet ist, wobei der Pumpeneinsatz (1) aufweist:
- einen Rotor (4) und eine Pumpenwelle (10),
- ein erstes Gehäuseteil (2) und ein zweites Gehäuseteil (3), zwischen denen der Rotor (4) um eine Drehachse (D) und relativ zu dem ersten und zweiten Gehäuseteil (2, 3) drehbar angeordnet ist, wobei die Pumpenwelle (10) verdrehfest mit dem Rotor (4) verbunden und in dem ersten Gehäuseteil (2) und in einer sackförmigen Ausnehmung des zweiten Gehäuseteils (3) drehbar gelagert ist,
- einen Hubring (12), welcher den Rotor (4) umgibt und zwischen dem ersten Gehäuseteil (2) und dem zweiten Gehäuseteil (3) angeordnet ist,
wobei
zwischen dem Aufnahmegehäuse (20) und dem zweiten Gehäuseteil (3) eine zweite Dichtung (8), insbesondere ein Dichtring, angeordnet ist, welche einen ersten Druckraum (23b), der zwischen der Stirnwand (20c) und dem zweiten Gehäuseteil (3) gebildet ist, in Bezug auf einen Saugraum (24), der zwischen der Umfangswand (20d) und dem Hubring (12) gebildet ist, abdichtet und
zwischen dem ersten Gehäuseteil (2) und dem Aufnahmegehäuse (20), insbesondere der Umfangswand (20d) des Aufnahmegehäuses (20), eine erste Dichtung (7), die beispielsweise die Abdichtung des Saugraums (24) nach außen hin oder zur Öffnung des Aufnahmegehäuses (20) hin bewirkt, angeordnet ist, wobei der Saugraum (24) zwischen der ersten Dichtung (7) und der zweiten Dichtung (8) gebildet ist, und
zwischen dem zweiten Gehäuseteil (3) und der Stirnwand (20c) des Aufnahmegehäuses (20) ein Dichtelement (9) angeordnet ist, welches einen zweiten Druckraum (23c) ringförmig umgibt.

Pump, comprising a receiving housing (20) which forms a pot-shaped receiving space (25) with an end wall (20c) and a peripheral wall (20d), a pump insert (1) which is arranged in the receiving space (25), the pump insert ( 1) has:
- a rotor (4) and a pump shaft (10),
- a first housing part (2) and a second housing part (3), between which the rotor (4) is arranged so as to be rotatable about an axis of rotation (D) and relative to the first and second housing parts (2, 3), the pump shaft (10 ) is non-rotatably connected to the rotor (4) and rotatably mounted in the first housing part (2) and in a bag-shaped recess of the second housing part (3),
- a cam ring (12) which surrounds the rotor (4) and is arranged between the first housing part (2) and the second housing part (3),
where
A second seal (8), in particular a sealing ring, is arranged between the receiving housing (20) and the second housing part (3), which seal forms a first pressure chamber (23b) between the end wall (20c) and the second housing part (3). is, with respect to a suction space (24) formed between the peripheral wall (20d) and the cam ring (12), seals and
between the first housing part (2) and the receiving housing (20), in particular the peripheral wall (20d) of the receiving housing (20), a first seal (7) which, for example, seals off the suction chamber (24) from the outside or towards the opening of the receiving housing (20) effected towards, is arranged, wherein the suction space (24) is formed between the first seal (7) and the second seal (8), and
A sealing element (9) is arranged between the second housing part (3) and the end wall (20c) of the receiving housing (20) and surrounds a second pressure chamber (23c) in the form of a ring.
