Abstract (en)
[origin: EP0890741A2] The housing (2) of the unit contains a rotatable shaft (3) connecting a main hydropump (4) on one side of the housing to a secondary hydropump (5) on a second end side (10) of the housing. The housing wall incorporates at least a suction pipe (14) supplying hydraulic medium to the pumps as well as at least a first filter (15) set in the suction pipe to filter the hydraulic medium. A loading pump (20) such as a gearwheel or turbine pump rotationally secured to the shaft and set inside the housing supplies the hydraulic medium through a second integrated filter (21) to the main pump via a pressurised line (19) also integrated in the housing wall (7).
