The A4VG axial piston variable pump in swash plate design for hydrostatic closed circuit transmissions
– Circulation is proportional to travel speed and displacement and is infinitely variable
– Output circulation will increase with the swivel angle of the swash plate from to its highest worth
– Stream path changes smoothly when the swash plate is moved through the neutral placement
– A extensive range of highly adaptable control units is accessible for distinct manage and regulating features
– The pump is geared up with two pressure-aid valves on the substantial force ports to shield the hydrostatic transmission (pump and motor) from overload
– The high-pressure relief valves also function as boost valves
– The built-in enhance pump functions as a feed and management oil pump
– The optimum increase force is restricted by a created-in boost force relief valve
– The integral strain lower-off is standard
