Title:
HYDRAULIC SYSTEM FOR A HYDRODYNAMIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2015/044326
Kind Code:
A3
Abstract:
The invention relates to a hydrodynamic machine, 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 together form a toroidal working chamber (4), and comprising an electrohydraulic system. The electrohydraulic system comprises an open-loop and closed-loop control unit (22), a pump (11), a heat exchanger (19), a working-medium accumulator (10), a valve (9), and a line system. Working medium can be pumped by means of the pump (11) from the working-medium accumulator (10) into the working chamber (4) through the line system. In order to improve the electrohydraulic system, the electrohydraulic system according to the invention is changed in such a way that the valve (9) can be switched between a first position, the non-braking position, and a second position, the braking position, and the line system is designed in such a way that working medium can be pumped into the working chamber (4) by means of the pump (11) in both positions.
