ABSTRACT:
A hydrodynamic clutch with a generally horizontal axis, specifically for underground operation. The clutch includes a primary wheel, a secondary wheel, a housing which comprises two essentially axially perpendicular end walls as well as a peripheral wall which is essentially concentric to the axis of the clutch, a scooping bowl fastened to the primary wheel, forming a scooping space and revolving jointly with the primary wheel (rotor), outlet bores discharging from the working space into the scooping space, and a scooping pipe dipping into the scooping space. At least one antechamber has an inlet port for receiving leakage water entrained and thrown off by the outside surface of the rotor. A line is used for transfer of operating fluid from the antechamber to the scooping space.
