Oil supplying device for turboshaft engine of airplane, has oil supply unit with start-up assistance pump which provides power to allow functioning of starters/generators, where start-up assistance pump is placed in parallel to main pump

摘要

The device has oil supply units (110, 120) for supplying the oil to engine enclosures and to starters/generators (21, 22), respectively. The oil supply unit (120) has a main pump (130) i.e. volumetric pump, that is driven by mechanical coupling with an engine of an aircraft. The unit (120) has an auxiliary start-up assistance pump (140) which provides sufficient power to allow the functioning of the starters/generators. The start-up assistance pump is placed in parallel to the main pump.
