Seal arrangement for turbo machine i.e. airplane engine, for sealing bearing devices, has fluid guide elements plunged in region in reservoir, and sealing unit includes oil inflow and oil drain, where inflow and drain lie in pressure region
The arrangement has high and low pressure sleeve shafts (1, 2) coupled with a hydraulic sealing unit (8) that includes groove with a base that is radially and outwardly displayed. Fluid guide elements (10) are arranged in the groove, where the fluid guide elements are plunged in a region in an oil reservoir (20) on a radial outer side of the groove. The oil reservoir is formed by a centrifugal force, and the hydraulic sealing unit includes a separate oil inflow (21) and an oil drain (22), where the oil inflow and oil drain lie in a pressure region. An independent claim is also included for a turbo machine.
