The A4VG axial piston variable pump in swash plate design and style for hydrostatic shut circuit transmissions
– Flow is proportional to travel pace and displacement and is infinitely variable
– Output flow will increase with the swivel angle of the swash plate from to its highest worth
– Stream course adjustments efficiently when the swash plate is moved by means of the neutral placement
– A broad range of extremely adaptable handle units is obtainable for various control and regulating functions
– The pump is geared up with two pressure-relief valves on the substantial stress ports to shield the hydrostatic transmission (pump and motor) from overload
– The substantial-pressure reduction valves also operate as boost valves
– The integrated improve pump functions as a feed and management oil pump
– The optimum enhance pressure is restricted by a constructed-in enhance stress relief valve
– The integral strain minimize-off is common
