Eternal Hydraulic A6VE Plug-in Hydraulic Variable Motor
A6VE is a hydraulic variable plug-in motor with axial tapered piston rotary group of bentaxis design for hydrostatic drives in open and closed circuits. For axial piston units with bent-axis design, the pistons are arranged at an angle to the drive shaft.The pistons rest directly on the drive shaft where they generate torque depending on the pressure and swivel angle. The specific torque and displacement can be changed by adjusting the bent axis.
In the open circuit, the hydraulic fluid flows from the reservoir to the hydraulic pump from where it is transported to the hydraulic motor. From the hydraulic motor, the hydraulic fluid flows directly back to the reservoir. The output direction of rotation of the hydraulic motor can be changed, e.g. by a directional valve.
In the closed circuit, the hydraulic fluid flows from the hydraulic pump to the hydraulic motor and from there directly back to the hydraulic pump. The output direction of rotation of the hydraulic motor is changed, e.g. by reversing the flow direction in the hydraulic pump.
Our products have lower noise and longer life, can replace Rexroth type.

Application
Piston pumps are widely used in high-pressure, high-flow, high-power systems and where the flow needs to be regulated, such as mobile and construction equipment, engineering vehicles, heavy-duty planers, metal forming and stamping, machine tools, hydraulic presses, oilfield equipment, mining and metallurgical machinery, marine and other hydraulic systems.
The A6VE Variable plug-in motor converts hydrostatic flow into mechanical rotation and controls or regulates this. It is designed for mobile applications such as construction machinery.
