Key Features of A4VG Variable Axial Piston Pump
A4VG variable axial piston pump is an integrated auxiliary pump for boost and pilot oil supply.
Flow direction changes smoothly when the swashplate is moved through the neutral position.
Variable axial piston pump of swashplate design for applications in a closed circuit.
low rate is proportional to the driving speed and displacement and can be infinitely varied from the minimum to maximum displacement.
Flow direction changes smoothly when the swashplate is moved through the neutral position.
A large variety of controls.
A pressure relief valve is provided on each pressure port to protect hydrostatic transmission from overloading.
High-pressure relief valves with integrated boost function.
The integrated boost pump has functions to replenish and control oil.
Maximum boost pressure is limited by an integrated boost pressure relief valve.
