Abstract (en)
[origin: WO2020260450A1] The present invention relates to a mobile work machine, in particular a wheeled loader, having a hydraulic circuit and having a pump (P) for conveying a hydraulic medium through the hydraulic circuit and having at least one control block (CB) having an inflow control edge (ZK) and an outflow control edge (AK) for controlling the flow of the hydraulic fluid, wherein the work machine has a working tool and a cylinder for actuating the working tool and wherein the cylinder has an outflow (A) and an inflow (B) for the hydraulic fluid, the outflow being fluidically connected to the outflow control edge and the inflow being fluidically connected to the inflow control edge, the inflow control edge having no fine control notches or fewer fine control notches than the outflow control edge, which has one or more fine control notches, such that, in the event of a load pulling on the working tool, the outflow control edge throttles the outflow volume through the outflow of the cylinder.
