Rexroth A4VG Features: Swashplate axial piston variable pump for closed loop hydrostatic transmission ◆ flow is proportional to the drive speed and displacement and stepless variable; ◆ flow with the swash angle from zero to its maximum; ◆ the swash plate can be placed over the median flow smoothly change the flow direction; multiple variables ◆ easy way with a variety of control and regulation systems match; ◆ high-pressure oil pump pressure relief valve to protect the side with two static Hydraulic (pump and motor) from overload; ◆ high pressure relief valve also has the function of charge; ◆ Built-in charge pump and an auxiliary pump is used to control the pump; ◆ maximum charge pressure from a built-up oil spill to limit; ◆ whole series with a built-pressure shut-off valve; Typical applications: concrete pump truck, heavy duty hydraulic flatbed, pump station technical parameters: the value table (theoretical value, and is not considered ηmh ηv; value after rounding) 1) Limit Maximum speed: - consumes half the power angle (for example, when Vg man and PN / 2 2) Gaucher maximum speed: - no-load operation at high speed - during engine overspeed: △ p = 70 ... 150 bar and Vg max - at the time of the reverse peak load: △ p <300 bar and t <5 seconds.
