The A4VG axial piston variable pump in swash plate design for hydrostatic shut circuit transmissions
– Circulation is proportional to drive velocity and displacement and is infinitely variable
– Output flow boosts with the swivel angle of the swash plate from to its optimum benefit
– Flow direction changes efficiently when the swash plate is moved by way of the neutral place
– A broad assortment of very adaptable management products is offered for distinct handle and regulating features
– The pump is outfitted with two stress-relief valves on the large strain ports to safeguard the hydrostatic transmission (pump and motor) from overload
– The high-strain relief valves also function as enhance valves
– The built-in boost pump functions as a feed and management oil pump
– The greatest boost pressure is minimal by a constructed-in improve force relief valve
– The integral strain minimize-off is common
