Electrically driven coolant pump |
| 摘要 |
The drive motor (13), preferably a synchronous motor, has a hollow rotor shaft (4) through which the refrigerant flows to the impeller (5). The shaft roller bearings (7,8) are sealed against the entrance of the refrigerant by seals (9) integrated in the bearing cages (7a, 8a). In turn these keep the stator chamber (11) free from liquid. |
