Title:
HYDRAULIC SYSTEM FOR A HYDRODYNAMIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2015/044328
Kind Code:
A3
Abstract:
The invention relates to a hydrodynamic machine for producing a braking torque, in particular a hydrodynamic retarder, comprising a first blade wheel, in particular a rotor (1), and a second blade wheel, in particular a stator (2), arranged concentrically to the first blade wheel, which blade wheels together from a toroidal working chamber (4), and comprising a hydraulic system. The hydraulic system comprises an open-loop and closed-loop control unit (22), a pump, a heat exchanger, a valve, a working-medium accumulator (10), and a line system. A volumetric flow circulation of the working medium through the line system and the working chamber can be produced by means of the pump. According to the invention, the braking power or the braking torque is controlled in an open-loop/closed-loop manner by means of a pressure control valve.
