A device and a method for Controlling the Clamping pressure is provided when a member is subjected to tension as a function of the Clamping force of the Clamping Member reference.The device has a Cylindrical Hole, Cover, a piston Member coupled to the reference Voltage is supported so that it can move longitudinally along the Axis.The cover and the piston cover, a pressure Chamber which can be activated by a pressure Medium for the implementation of an axial Movement of the piston shock against the Clamping force of the tension member of reference input, and an output can be connected to the P Clamping pressure.The device further includes a Valve Unit for Controlling the application of pressure to the Clamping pressure, where the Valve Unit can be directly controlled by the shaking Movement of the piston.The Method according to the invention provides for the attachment of members of tension as a function of the Clamping force of the tension Member Unit of reference for the piston Cylinder, The Piston is maintaining the reference Voltage in a Member State Default voltage.When a State of uniform tension is achieved in all members of tension in the course of the subject of the tension Member by a Clamping pressure, flow of pressure to the Clamping pressure is directly disturbed by the Jolt piston movement NG.
