A process of manufacturing a component for a hydrodynamic machine in which the component comprises a base body ( ) and a plurality of blades ( ) which are to be installed on the base body ( ). The process comprises the steps of installing the plurality of blades ( ) on the base body ( ) by a shaped fitted connection with the base body ( ) by applying continuous pressure against the base body ( ) and using a prefabricated torus as the base body ( ). The prefabricated torus is pressed by a pressure roller ( ) against the plurality of blades ( ) while holding the plurality of blades ( ) in a device ( ) against the pressure of the pressure roller ( ). A component for a hydrodynamic machine, comprising a base body ( ) and a plurality blades ( ) installed by the inventive process, is also disclosed.

Fitting of blades in hydrodynamic machines

The device for complete draining of the oil in a component of a motor vehicle such as hydraulic steering, transmission with converter or automatic transmission which has within the component, an oil drain valve for at least one oil chamber in the component, which oil drain valve is automatically opened when the plug of the component is removed.
