Abstract (en)

[origin: WO8701630A1] A riveting tool for driving threaded or blind nuts comprises a feed device which can be operated for the upsetting process and conferring an axial movement on the threaded or tie-bolt. This feed arrangement comprises a cylinder and piston arrangement consisting of a compression piston and an operating piston (211, 14) the operating and compression pistons (14, 211) are returned by diverting the pressurized medium through the rear part (102, 210) of the pistons, thus making return springs unnecessary. A channel for pressurized medium (201, 205, 104) extends from the point of admission (207) of the pressurized medium to the rear chamber (102) passing through the handle portion (200). The rear chamber (102) is closed off on one side of the rear part of the operating piston (14).
