The A4VG axial piston variable pump in swash plate design for hydrostatic shut circuit transmissions
– Circulation is proportional to drive speed and displacement and is infinitely variable
– Output flow will increase with the swivel angle of the swash plate from to its optimum price
– Flow course adjustments smoothly when the swash plate is moved via the neutral position
– A extensive range of highly adaptable management products is accessible for distinct control and regulating functions
– The pump is geared up with two stress-aid valves on the substantial pressure ports to protect the hydrostatic transmission (pump and motor) from overload
– The substantial-stress reduction valves also operate as improve valves
– The built-in boost pump functions as a feed and manage oil pump
– The optimum enhance force is restricted by a created-in increase strain reduction valve
– The integral strain cut-off is regular
