The A4VG axial piston variable pump in swash plate design and style for hydrostatic closed circuit transmissions
– Circulation is proportional to push pace and displacement and is infinitely variable
– Output flow will increase with the swivel angle of the swash plate from to its greatest worth
– Stream path alterations efficiently when the swash plate is moved through the neutral place
– A extensive selection of very adaptable handle gadgets is accessible for various manage and regulating features
– The pump is geared up with two strain-aid valves on the high pressure ports to shield the hydrostatic transmission (pump and motor) from overload
– The high-force reduction valves also operate as enhance valves
– The integrated increase pump functions as a feed and control oil pump
– The maximum boost stress is limited by a built-in improve pressure aid valve
– The integral stress minimize-off is standard
