Abrégé

A hydrodynamic machine, and especially a hydrodynamic coupling, for a turbine compound system includes (a) a bladed primary wheel and a bladed secondary wheel which together form an operating space which is filled or can be filled with operating medium, and (b) a housing which encloses the primary wheel and the secondary wheel and which is manufactured from sheet metal. The housing is manufactured from at least two separate sheet metal components which are placed on the primary wheel and/or the secondary wheel, are aligned with each other at a joint abutment location, and are welded together. In the area of the welded joint abutment, a relief which is open toward the joint abutment is provided and which extends along the joint abutment in the surface of the primary wheel and/or the secondary wheel.

Abrégé

The present invention relates to a hydrodynamic machine, especially a hydrodynamic retarder, including a bladed primary wheel and a bladed secondary wheel which are arranged opposite of each other axially with respect to their blade configurations such that they jointly form a working chamber. The working chamber can be filled with a working medium for one operating state in order to transmit torque from the primary wheel to the secondary wheel by means of a circulatory flow of the working medium. The working chamber can be emptied of the working medium for a non-operating state in order to prevent a transmission of torque from the primary wheel to the secondary wheel. A suction apparatus is connected with a fluidic connection to the working chamber in order to suck off working medium and/or air from the working chamber for forming a negative pressure in the working chamber in the non-operating state.
