<p>The pump (1) has a housing (2) and a drive shaft (3) which is accommodated in said housing (2) and by which at least one pump piston (18) is driven at least indirectly. The drive shaft (3) is mounted via at least one sliding bearing arrangement (4a, 4b) such that it can be rotated about a driveshaft axis (5), and has a drive region (24), via which the drive shaft (3) is driven. The sliding bearing arrangement (4a, 4b) has a bearing bore (6) and a bearing shaft section (7) which extends through said bearing bore (6). The sliding bearing arrangement (4a, 4b) has a bearing play (X) which extends in the radial direction with regard to the rotational axis (5) of the drive shaft (3) between the bearing bore (6) and the bearing shaft section (7) and has a smaller value (X1) in an intermediate region (26) which lies between the axial bearing edges (9a, 9b) than at the bearing edges (9a, 9b). The intermediate region (26) with the smallest value (X1) for the bearing play (X) is arranged offset from the drive region (24) of the drive shaft (3) with regard to the bearing centre (8) of the sliding bearing arrangement (4a, 4b).</p> |
