Title: HYDRODYNAMIC ASSEMBLY
Abstract:
The invention relates to a hydrodynamic assembly, characterised by the following features: the hydrodynamic assembly (2) is devoid of a primary impeller shell that is coupled to the primary impeller (3) in a rotationally fixed manner and surrounds the axis and circumference of the secondary impeller (4); the internal wall (11) of the static housing (6) and at least one respective section of the external circumference of the primary impeller and secondary impeller delimit an impeller side chamber (7, 8) in an axial direction; a gap (13) is provided in a radial direction between the primary impeller and the secondary impeller and an internal wall section that faces towards the impellers in a radial direction; at least one section of said gap is sealed in relation to the impeller side chambers (7, 8) by means of a contactless sealing system (15); the assembly is provided with at least one outlet (16) from the working chamber, located on the impeller or between the two impellers; the exit (16) leads into the section of the gap that is sealed in relation to the impeller side chambers by means of the contactless sealing system.
