Abstract (en)

[origin: EP2541072A2] The arrangement has a variable flow pump (20) that is in fluid communication with a bucket (12) and hydraulic cylinders (14-18) of an excavator (1) through individual pressure compensators associated with the bucket and the cylinders, and adjustable inlet orifice plates. The pump is electro-proportionally adjustable. The compensators are pressurized along opening direction by pressure downstream of the plates and acted upon by actuating pressure along closure direction, where the actuating pressure is adjustable by a central control unit (22). An independent claim is also included for a method for actuating hydraulic loads.
