The A4VG axial piston variable pump in swash plate style for hydrostatic closed circuit transmissions
– Movement is proportional to travel speed and displacement and is infinitely variable
– Output movement increases with the swivel angle of the swash plate from to its highest worth
– Movement direction changes smoothly when the swash plate is moved by way of the neutral position
– A vast variety of extremely adaptable control gadgets is offered for various manage and regulating capabilities
– The pump is outfitted with two pressure-aid valves on the substantial strain ports to shield the hydrostatic transmission (pump and motor) from overload
– The substantial-force aid valves also perform as boost valves
– The integrated improve pump acts as a feed and management oil pump
– The highest boost force is limited by a constructed-in boost force aid valve
– The integral force minimize-off is standard
