Coupling control device

A coupling control device, comprising at least one valve for controlling at least one coupling;

• at least one throttle arrangement arranged between said at least one valve and the at least one coupling, said valve being formed as a pressure control valve which is a pressure reducing valve for controlling a volume flow to the at least one coupling during a filling process;
• a control unit which is formed as a unit selected from the group consisting of a control unit formed as an electromagnet and an electromagnetic control unit with a precontrol valve;
• a spring and a return conduit connected with said pressure control valve;
• said return conduit being connected with a working conduit which is connected to a working connection of said pressure control valve, said pressure control valve being controllable so that before halves of the at least one coupling come to abutment with one another a pressure before said throttle arrangement is lowered, said at least one throttle arrangement being formed as an active throttle arrangement during filling of the at least one coupling, and which during the filling process of the at least one coupling produces a pressure drop, and after abutting of the both coupling halves a pressure before said throttle arrangement and a pressure in a pressure chamber of the at least one coupling are substantially identical.
