Abstract: Hydraulic tool for driving a pulling and/or pressing device, comprising a drive shaft that can be mounted to a screwdriver, wherein the drive shaft is operable to drive a hydraulic pump that pumps hydraulic fluid into the operating chamber of a hydraulic power piston. The hydraulic tool may in particular be configured as a riveting or punching attachment for a cordless screwdriver.

Abstract: A method for joining at least two components, in particular two sheet components of a vehicle body, by a flow-formed rivet sleeve is disclosed. The flow-formed rivet sleeve includes a cladding region, a first edge region, and a second edge region. A traction shaft including a base body and a head is introduced in the flow-formed rivet sleeve and the flow-formed rivet sleeve is inserted into respective through openings of the components. By a relative movement of the traction shaft to the flow-formed rivet sleeve, the flow-formed rivet sleeve is widened in the first edge region and is brought into contact with one of the components. The second edge region is bent towards the other component by a reshaping tool surrounding the traction shaft and is brought into contact with the other component.

Abstract: The invention relates to a nozzle head for a jet cleaning device, the nozzle head having a central axis and a front face, being provided with a central bore aligned with the central axis and further with a multitude of straight supply bores which pass with their axes in an acute angle to the central axis from the central bore to the front face, and the supply bores ending at the front face in receiving holes. One nozzle is inserted into each receiving hole and each nozzle is provided with a bore having a reduced diameter and ending at the front face such that pressurized fluid supplied via the supply bores is emerging jet-like from the front face. The receiving holes and thus the nozzle bore exits are arranged in a regular angular spacing and on different circles around the central axis.
