FIELD: pumps.SUBSTANCE: invention relates to a method pump flow deviation in pumping system. Working vehicle comprises a container for fluid medium; the first and the second pump with constant flow rate, wherein the flows of both pumps are parallel to each other; actuator; distributing valve with an open centre arranged by the fluid medium between the group of pumps and actuator; electro-hydraulic diverter connected by fluid with the point between the second pump and distribution valve and reservoir for fluid medium; working vehicle speed transducer. Operator input device provides manual selection of adjustment of deviation of position of the vehicle seat. Controller receives speed signal or deviation adjustment. It determines whether speed parameter satisfies preset criterion or determines the state of the selected deviation adjustment. Then it generates commands for deflector to open if speed parameter satisfies preset criterion or if selected deviation adjustment is in the state of flow deflection.EFFECT: higher operating efficiency.19 cl, 6 dwg |
