A freewheel (18) is arranged between the primary rotor (4) and the secondary rotor (5).

A caster assembly includes a primary wheel (10) and a secondary wheel (14).

The bridges (3) attached to the base (2) are provided with wheels (4) at the two ends, and each of the wheels has a bearing; Each of the turning wheels (6) includes a fixing wheel (61) a bearing (62) and a base wheel (63) .

A single primary impeller (20) is mounted on the shaft for receiving fluid from the primary inlet and discharging fluid through the primary discharge.

The invention relates to a hydrodynamic clutch comprising a primary gear and a secondary gear, said gears forming a toroidal working chamber.

The primary gear is located on a drive shaft or is integrated into said shaft.

The invention relates to a hydrodynamic coupling for wind plants, comprising a primary wheel and a secondary wheel, forming together a working chamber.

A first externally toothed primary drive gear (51) fast on an end wall (19) of the drum (15) drives a first primary drive shaft (47a) through a first primary pinion (50a).

A screw bolt (8) pass through the base wheel (63) the bearing (62) the fixing wheel (61) and the bended end to engage with a nut.

The invention relates to a hydrodynamic clutch which comprises a primary wheel and a secondary wheel which together form a toroidal operating space which can be filled with a functional substance.

A bearing is inserted, at least indirectly, between the primary wheel and the secondary wheel, and absorbs the radial forces and/or axial forces acting between the blade wheels.

The primary wheel and the secondary wheel together form a working chamber that can be filled with a working medium, and are mounted in such a way that they can rotate in relation to each other.

All fluid introduced to the secondary inlet originates from the primary discharge or may be diverted from the fluid flow upstream of the centrifugal pump assembly or the primary impeller.

A trailer has a body, a primary wheel, and an adjustable leg for providing secondary support.

The invention relates to a hydrodynamic non-positive-displacement machine, in particular, a retarder with a bladed primary wheel (1) and with a bladed secondary wheel (2) that, together, form a working space (3) which can be filled with a working medium.
