Description
– Variable displacement axial piston pump with swash plate design for closed loop hydrostatic drives
– The flow is proportional to the speed and displacement of the drive.
– The flow increases in relation to the swash plate angle, from zero to its maximum value.
– The flow direction changes gradually when the swash plate is moved to the neutral position.
– Two safety valves are provided on the high-pressure ports to protect the hydrostatic drive (pump and motor) from overload.
– The high-pressure safety valves also function as supercharger valves.
– The integrated boost pump acts as a feed pump and control pressure supply.
– The maximum boost pressure is limited by the integration of a boost pressure relief valve.
