\u00a0
The A4VG axial piston variable pump in swash plate style for hydrostatic closed circuit transmissions
– Stream is proportional to generate speed and displacement and is infinitely variable
– Output circulation will increase with the swivel angle of the swash plate from to its greatest worth
– Movement path modifications easily when the swash plate is moved through the neutral position
– A extensive assortment of very adaptable control gadgets is offered for distinct control and regulating functions
– The pump is equipped with two pressure-aid valves on the substantial force ports to protect the hydrostatic transmission (pump and motor) from overload
– The higher-force reduction valves also perform as improve valves
– The integrated enhance pump functions as a feed and control oil pump
– The optimum increase strain is limited by a created-in improve stress reduction valve
– The integral stress cut-off is CZPT<\/p>\n
