The A4VG axial piston variable pump in swash plate style for hydrostatic shut circuit transmissions
– Flow is proportional to travel speed and displacement and is infinitely variable
– Output stream boosts with the swivel angle of the swash plate from to its optimum price
– Flow direction alterations easily when the swash plate is moved through the neutral place
– A broad variety of highly adaptable manage units is obtainable for different management and regulating features
– The pump is equipped with two force-reduction valves on the higher force ports to defend the hydrostatic transmission (pump and motor) from overload
– The large-stress reduction valves also perform as increase valves
– The integrated enhance pump acts as a feed and manage oil pump
– The maximum boost force is constrained by a constructed-in increase stress relief valve
– The integral force cut-off is common
