Abstract
The invention relates to a method for regulating the maximum speed of a working machine (12), in particular an air compressor in a vehicle. Said working machine is driven by means of a motor (10), using a hydrodynamic coupling (11), which comprises a working chamber (3) that is partially or fully filled with a working medium for transmitting a torque from a drive side (11.1) equipped with an impeller (1) to a driven side (11.2) equipped with a turbine wheel (2). The method comprises the following steps: the speed of the working machine, of the driven side of the hydrodynamic coupling, of the drive side of the hydrodynamic coupling and/or of the motor is detected; a maximum permissible value for the speed is defined and compared to the detected speed; if the detected speed exceeds the maximum permissible value, the quantity of working medium in the working chamber of the hydrodynamic coupling is automatically reduced by the opening or passage of medium through an outlet that is connected to the working chamber.
