Rexroth A4VG hydraulic piston pumps and parts

-Axial piston swash plate structure variable pump, used for the static hydraulic transmission of the closed loop

- flow rate is proportional to the driving speed and displacement, can be stepless regulating

- output flow with the swinging Angle of inclined plate increased from zero to maximum

- every high side are equipped with two relief valve, used to prevent hydrostatic transmission (pump and motor) overload

- overflow valve also has the function of fill oil valve - built-in fill oil pump used for oil supply and control pump

Compact Structure and high quality.
