The A4V is a variable displacement pump of axial piston,swashplate design for hydrostatic transmissions in closed circuits.
Flow is proportional to drive speed and displacement is infinitely variable.
Output flow increases with swivel angle from O to its maximum value . Swivelling the swashplate over centre causessmooth reversal of the direction of flow.
The various control and regulating functions are catered for by the well-matched range of control and regulating devices.
The pump is equipped with a pair of crossline relief valves to protect the high pressure side of the Hydromatic transmission from overload. These valves also act as boost inlet valves.
In the standard model, the A4V is supplied with a built-on auxiliary pump,which acts as boost supply and pilot pump.Maximum boost pressure is limited by a built-in pressure relief valve.
As standard, filtration of the suction line of the boost pump is recommeded,lf required, however, filtration may be in the boost pressure line, via either a line mounted or direct mounted filter.
Variable pumps type A4V can be supplied with a through drive, which may be used for mounting a further gear pump asan additional boost pump (for installation with leakage greater than 70% of the output flow of the auxiliary pump), or for mounting a further variable pump type A10V, which may be used to power a separate circuit.
