The A4VG axial piston variable pump in swash plate design and style for hydrostatic shut circuit transmissions
– Circulation is proportional to generate speed and displacement and is infinitely variable
– Output circulation raises with the swivel angle of the swash plate from to its highest benefit
– Movement path changes easily when the swash plate is moved via the neutral placement
– A extensive selection of very adaptable manage products is obtainable for different control and regulating capabilities
– The pump is outfitted with two stress-aid valves on the substantial strain ports to shield the hydrostatic transmission (pump and motor) from overload
– The higher-force reduction valves also operate as increase valves
– The integrated boost pump functions as a feed and management oil pump
– The greatest increase force is constrained by a created-in boost strain aid valve
– The integral strain cut-off is common
