| 摘要 |
The invention relates to a pump (1) for conveying a liquid, comprising at least one pump housing (2) with at least one inlet (3) and at least one outlet (4), wherein an eccentric (5) is mounted on the pump housing (2), the eccentric being rotatable about an axis (6) relative to the pump housing (2). A deformable element (7) is arranged between the pump housing (2) and the eccentric (5), wherein a conveying channel (8) is formed with the deformable element (7) and a circumferential surface (13) of the pump housing from the at least one inlet (3) to the at least one outlet (4). Wherein, further, the deformable element (7) from the eccentric (5) is thus pressed, in sections, against the pump housing (2) in such a way that at least one displaceable seal (9) of the conveying channel (8) and one closed pump volume (10) is formed in the conveying channel (8), which by a movement of the eccentric (5) can be displaced to convey liquid along the conveying channel (8) from the inlet (3) to the outlet (4). At least one channel cross-section (45) of the conveying channel (8) is limited by the circumferential surface (13), a receding channel surface (46) of the deformable element (7) and at least one sealing contact (12) between the circumferential surface (13) and the deformable element (7). |
