<p>The motor pump device (A) has a gilled pipe (1) locked in both ends by covers (3,4). The gilled pipe defines an oil reservoir (R) and a receiving chamber for two hydraulic pumps (P1,P2,P3) and oil-immersed electric motors (M1,M2), and has a ventilator (41) installed on the cover in the same oil reservoir. The two oil-immersed electric motors are separated from each other. Each of the oil-immersed electric motor stands in drive connection with the hydraulic pump.</p> |
