A rapid coupling system for establishing a connection of at least two pressurized lines in a pressure sealed manner is provided. A first coupling plug element has an operating mechanism, including a journal, in a connecting block thereof. A second coupling socket element is adapted to be connected to the first coupling element in a pressure sealed manner. A control unit is arranged in a socket element connecting block and includes a displaceable plunger having at least one cam. A pressure relief unit is connectable to at least one of the pressure lines via a pressure relief connection. When the first and second coupling elements are connected to one another, the journal of the operating mechanism displaces the control plunger, causing at least one cam of the control plunger to engage the pressure relief unit.

1. A rapid coupling system for establishing a pressure sealed connection of at least two pressurized lines, comprising:a first coupling element connectable to the at least two pressurized lines and comprising a plug element having an operating mechanism in a connecting block thereof; a second coupling element adapted to be connected to the first coupling element in a pressure sealed manner, the second coupling element comprising a socket element having a connecting block, and a control unit arranged in the socket element connecting block and comprising a displaceable plunger having at least one cam; and a pressure relief unit connectable to at least one of the pressurized lines via at least one pressure relief connection; whereby upon connecting the first and second coupling elements, the operating mechanism displaces the control plunger, causing at least one cam of the control plunger to engage the pressure relief unit. 2. The rapid coupling system of claim 1, wherein the operating mechanism comprises a journal with which the control plunger cooperates and which is particularly arranged on the same axis with the control plunger.3. The rapid coupling system of claim 2, wherein the pressure relief unit comprises the control unit, the pressure relief connection, at least one pressure relief valve system, at least one pressure relief chamber and at least one pressure relief line.4. The rapid coupling system of claim 3, wherein the at least one pressure relief valve system comprises at least one valve spring and at least one valve ball.5. The rapid coupling system of claim 3, wherein each pressure relief connection is allocated at least one pressure relief valve system.6. The rapid coupling system of claim 3, wherein several pressure relief valve systems of the pressure relief unit are conducted towards at least one pressure relief chamber and at least one pressure relief line.7. The rapid coupling system of claim 3, wherein the pressure relief valve system is arranged radially to the control plunger.8. The rapid coupling system of claim 3, wherein the control unit and the pressure relief chamber with its pressure relief line are arranged on the same axis.9. The rapid coupling system of claim 1, wherein the first coupling plug element comprises a valve between a channel and a chamber and a sealing unit between a tappet and a housing.10. The rapid coupling system of claim 1, wherein the second coupling socket element comprises a sealing unit between a sliding element and a housing element.11. The rapid coupling system of claim 1, wherein during a coupling process of the first and second coupling elements the respective connecting blocks thereof are simultaneously displaceable against each other.12. The rapid coupling system of claim 6, wherein the journal that operates the control plunger opens a passage from a channel in the socket element in a first coupling step, wherein by means of the cam of the control plunger the pressure relief valve towards a pressure relief chamber is opened.13. The rapid coupling system of claim 12, wherein a valve comprises in a second coupling step a connection between the channel and the pressure relief chamber through the pressure relief valve, via the chamber, passing by the sealing unit through the channel, via the pressure relief connection through the pressure relief valve system, wherein by means of the cam of the control plunger the pressure relief valve system towards the pressure relief chamber and the adjacent pressure relief line is kept open to enable a pressure compensation inside the rapid coupling system.14. The rapid coupling system of claim 13, wherein the journal displaces the control plunger axially in a third coupling step thus connecting the chamber and the channel with each other while simultaneously releasing the valve, while the cam of the control plunger keeps open the pressure relief valve system and releases the pressure relief connection towards the pressure relief chamber and the adjacent pressure relief line to enable a pressure compensation inside the rapid coupling system.15. The rapid coupling system of claim 14, wherein in a fourth coupling step due to a further axial displacement of the journal the control plunger is pushed completely into the pressure relief valve system, wherein the cam of the control plunger is passing by the pressure relief valve system and the pressure relief connection towards the pressure relief chamber and the adjacent pressure relief line in the rapid coupling system is closed.16. The rapid coupling system of claim 15, wherein the cam releases a valve ball thus causing the pressure relief valve system subject to the action of a valve spring to travel to its closing position.17. A rapid coupling system according to claim 13, wherein in the second coupling step the pressure relief valve can be opened in that a tappet actuates a push pin pushing it into the valve.
