The A4VG axial piston variable pump in swash plate design and style for hydrostatic shut circuit transmissions
– Stream is proportional to travel pace and displacement and is infinitely variable
– Output circulation will increase with the swivel angle of the swash plate from to its maximum value
– Flow direction alterations effortlessly when the swash plate is moved through the neutral situation
– A broad selection of very adaptable manage units is available for diverse control and regulating features
– The pump is geared up with two strain-relief valves on the large force ports to shield the hydrostatic transmission (pump and motor) from overload
– The high-pressure reduction valves also operate as enhance valves
– The built-in improve pump functions as a feed and manage oil pump
– The highest boost stress is restricted by a constructed-in improve stress reduction valve
– The integral strain minimize-off is normal
