The invention relates to a system for producing a sealed connection of a press connector to a workpiece, in particular to a pipe, preferably to a plastic pipe, with a pressing tool for pressing a press connector and with a pressure tool for driving the pressing tool. The pressure tool is arranged to output a hydraulic pressure at a pressure generation point The pressing tool is arranged to receive a hydraulic pressure at a pressing location and to press a press connector accordingly. The pressure tool and the pressing tool are connected via a hydraulic pressure transmission connection, the pressure generation location and the pressing location being remote from each other. A corresponding method for producing a tight connection of a press connector to a workpiece, in particular to a pipe made of a flexible material, preferably a plastic pipe, as well as a press force translator and a press tool are also described.

Pressing tool, system and method for producing a tight connection of a press connector to a workpiece

A pressing tool for pressing fittings to produce pipe connections, with two opposing pressing jaws, each having a pressing section and a lever section, and having a retaining element for swivel connecting the pressing jaws, wherein the pressing sections form a receiving section and wherein pressing the lever sections apart causes the receiving section to close. An actuator spindle, a spindle nut and at least two actuator levers are provided, and each actuator lever is swivel connected at one end to the lever section of a pressing jaw and each actuator lever is swivel connected at another end to the spindle nut. A method for pressing fittings for the production of pipe connections is also disclosed.

The invention is based on the technical problem of improving the pressing in of large press fittings, said problem being solved by a device for transmitting a mechanical force for driving a pressing device for press fittings, having a storage container () for hydraulic fluid, having a pump cylinder (), having a working cylinder (), having a first line () for connecting the storage container () to the pump cylinder (), having a second line () for connecting the pump cylinder () to the working cylinder (), and having a third line () for connecting the working cylinder () to the storage container (), wherein means () for preventing a return flow into the storage container () are provided in the first line (), wherein means () for preventing a return flow into the pump cylinder () are provided in the second line (), wherein switching means () for opening and closing the third line () are provided, and wherein the swept volume (VA) of the working cylinder () is configured to be greater than the swept volume (VP) of the pump cylinder (). The invention also relates to a corresponding method.
