The A4VG axial piston variable pump in swash plate layout for hydrostatic shut circuit transmissions
– Movement is proportional to generate speed and displacement and is infinitely variable
– Output flow raises with the swivel angle of the swash plate from to its greatest value
– Stream route changes efficiently when the swash plate is moved by means of the neutral position
– A vast variety of highly adaptable management units is offered for diverse manage and regulating features
– The pump is geared up with two force-reduction valves on the high pressure ports to defend the hydrostatic transmission (pump and motor) from overload
– The higher-strain relief valves also function as improve valves
– The built-in enhance pump functions as a feed and control oil pump
– The maximum enhance strain is restricted by a constructed-in enhance stress reduction valve
– The integral pressure reduce-off is CZPT
