The A4VG axial piston variable pump in swash plate design and style for hydrostatic shut circuit transmissions
– Stream is proportional to drive velocity and displacement and is infinitely variable
– Output flow raises with the swivel angle of the swash plate from to its maximum benefit
– Stream direction changes easily when the swash plate is moved via the neutral place
– A broad range of highly adaptable control units is available for diverse manage and regulating functions
– The pump is geared up with two force-reduction valves on the substantial force ports to defend the hydrostatic transmission (pump and motor) from overload
– The large-strain relief valves also perform as enhance valves
– The built-in enhance pump acts as a feed and manage oil pump
– The greatest increase strain is constrained by a created-in boost force reduction valve
– The integral pressure reduce-off is CZPT
