Abstract (en)

[origin: WO9604107A1] A hydraulic drive unit is disclosed, in particular for a portable hydraulic tool. The hydraulic high-pressure pump (102) of the proposed unit is arranged inside a ring reservoir (119), thus making for a compact design which results in short fluid paths between the ring reservoir (119) and the hydraulic high-pressure pump (102) and reduces the number of sealing points.
