摘要： A hydraulic pressing tool which is particularly suitable for pressing pipe fittings, and which has a hydraulic pump connected to an electric motor. With the aid of the hydraulic pump, hydraulic fluid is pumped from a tank into a piston chamber to operate the hydraulic piston. The pressure prevailing in the piston chamber is determined by means of a pressure sensor. When a pressure limit is reached, a solenoid valve is opened by the control device such that the hydraulic fluid flows back out of the piston chamber, through the channels, and into a reservoir.

摘要： A manual press device for connecting two work pieces by means of embossing, comprising a press tool, a converting device, and an electric motor. The electric motor is designed as a brushless electric motor, and preferably connected directly to a hydraulic pump without interconnecting a transmission.
