<p>The electrically operated pressing tool has a hydraulic pump driven by a drive unit (2) that effects on a piston cylinder unit (5). The hydraulic pump is actively connected with a roller support, whose roller is rolled up on a clamping jaw of a clamping tong. A pump receiving housing (30) is arranged in conduction free manner. The pump flange (326) is compressably fixed with an outlet valve of the hydraulic pump directing on a connection cylinder of the piston cylinder unit, and arises pressure fluctuations with small fluid pressure within the pump receiving housing.</p> |
