The A4VG axial piston variable pump in swash plate style for hydrostatic closed circuit transmissions
– Movement is proportional to generate pace and displacement and is infinitely variable
– Output stream raises with the swivel angle of the swash plate from to its highest value
– Flow route alterations effortlessly when the swash plate is moved via the neutral placement
– A extensive selection of hugely adaptable manage units is obtainable for different control and regulating features
– The pump is geared up with two stress-reduction valves on the large force ports to defend the hydrostatic transmission (pump and motor) from overload
– The high-force aid valves also function as enhance valves
– The built-in increase pump functions as a feed and manage oil pump
– The greatest improve stress is limited by a developed-in increase strain aid valve
– The integral stress reduce-off is standard
