For the drum generate in mobile concrete mixers A4VTG071, A4VGT090 series.
-Variable axial piston pump of swash plate design for hydrostatic drives in shut circuit
-The flow is proportional to the push pace and displacement.
-The flow will increase as the angle of the swash plate is altered from zero to its optimum benefit.
-Circulation path modifications smoothly when the swash plate is moved via the neutral place.
-Two strain-relief valves are supplied on the large force ports to shield the hydrostatic transmission (pump and motor) from overload.
-The high-force reduction valves also perform as improve valves.
-The integrated boost pump functions as a feed pump and control force supply.
-The highest increase stress is minimal by a developed-in enhance stress-relief valve.
-Tapered shaft option for direct travel shaft yoke installation.
