FIELD: electrical engineering.
SUBSTANCE: invention relates electrical engineering and electrical machine building, in submerged oil-filled motors designed to drive submerged pumps to pump fluids from wells. Proposed device comprises housing (1) representing hollow cylinder arranged vertically in operating position of the device, shaft (2) tightly fitted on the housing shaft running thrust bearings to be coupled with motor shaft. It comprises also, at least, one oil-filled chamber arranged in housing (1). It differs from known designs in that it comprises gate compartment (3) arranged the bottom of housing one to communicate with oil-filled chamber via, gate duct (4) fitted with lock open/close gate duct (4). Note that lower extension of shaft (2) is arranged in gate compartment (3).
EFFECT: shorter and simpler mounting, oil savings.
