Abstract

A hydrodynamic machine contains a bladed primary wheel driven by a rotary shaft and a bladed secondary wheel, which together form a work chamber filled with a working medium. The machine has a pressure pump for delivering a working medium from the work chamber. The pressure pump has a first inlet, which projects into the work chamber, and has a first inlet opening which is aligned with the rotary shaft in the circumferential direction. The pressure pump has a second inlet which projects into the work chamber and has a second inlet opening which is aligned to the rotary shaft in the circumferential direction opposite to the first inlet opening. The first and second inlets are joined to a common working medium channel behind the two inlet openings. The first and second inlets extend adjacent to each other in the same flow direction separated by a separation wall.
