ABSTRACT:
A riveting tool includes a tool body having a hydraulic controlled rivet shank clamping assembly and a rivet suction system. A control valve is provided for directing a flow of pressurized air to the rivet clamping assembly and the rivet suction system. The control valve includes a valve rod having a valve rod piston on an upper end and a plurality of radial steps arranged on an outer surface of a lower end. A trigger is mounted slidably in a trigger transverse guide in the tool body and a spring is located within the trigger transverse guide such that pressure applied to the trigger causes the valve rod to move within the control valve from a first to a second position. When the valve rod is in the first position, pressurized air is guided to the rivet suction system. When the valve rod is in the second position, pressurized air is guided to a space below a pneumatic piston. A space above the pneumatic piston is connected to the hydraulic cylinder of the hydraulic controlled rivet shank clamping assembly.
