Method and apparatus for the controlled limitation of the braking action of a retarder

Apparatus and procedure to maximally utilize the braking of a retarder

METHOD FOR OPERATING A RETARDER

Method for retarder control and control apparatus for the same

Power carrier i.e. braking torque, adjusting method for e.g. hydrodynamic oil retarder in drive train of motorvehicle, involves actuating control valve by regulating device based on transmitted housing pressure

Method for controlling hydrodynamic oil retarder for motor vehicle, involves detecting pressure between inlet valves and outlet valve after switching outlet valve to open position and maintaining intake valves in closed position

Method for retarder control and control apparatus therefor

Motor vehicle drive train with an engine and a hydrodynamic retarder

Method for controlling power transmission of hydrodynamic retarder, involves setting retarder braking torque based on primary impeller rotation speed and actuating pressure which is adjusted based on inlet pressure of working medium

Method for Limiting the Maximum Brake Performance Which Can Be Accessed of a Hydrodynamic Brake
