Abstract
A rotary vane pump for delivering a fluid, having a delivery device accommodated in a casing (2), a casing cover (3) arranged on one end face, and optionally with a bearing flange (4) adjoining the casing (2) on the side opposite to the casing cover (3). A seal (5,6) is arranged between the casing (2) and the casing cover (3) and optionally between the casing (2) and the bearing flange (4), and the seal (5,6) is inserted into a groove (8,9) formed in the casing cover (3), and optionally in the bearing flange (4), and/or in the respective end face (7) of casing (2). Also a leakage path (13) for the fluid extends between a delivery side (11) and suction side (12). The leakage path (13) extends on the inner side (14) of the seal at least in sections parallel to the seal (5,6).
