For the drum push in cell concrete mixers A4VTG071, A4VGT090 collection.
-Variable axial piston pump of swash plate style for hydrostatic drives in closed circuit
-The stream is proportional to the push velocity and displacement.
-The flow will increase as the angle of the swash plate is adjusted from zero to its greatest worth.
-Circulation course modifications efficiently when the swash plate is moved via the neutral place.
-Two pressure-reduction valves are offered on the higher pressure ports to shield the hydrostatic transmission (pump and motor) from overload.
-The high-stress aid valves also perform as improve valves.
-The integrated increase pump functions as a feed pump and management stress source.
-The highest enhance force is limited by a created-in enhance strain-relief valve.
-Tapered shaft choice for immediate push shaft yoke installation.
