Example of Valve Pump Unit Use
Press Structural Diagram
World Smallest Small Axial Piston Pump Unit
- Possible to mount on small space where it was not possible in the past.
- Energy saving as you can use hydraulic only at necessary place and time.
- Input shaft could be driven in bi rotational wise with high responsiveness.
- Wide application is possible as EHA: Electric Hydraulic Actuator combined with motor and actuator.
Safety
The device is protected from damage at overload as the safety valve is standardly equipped.
Response
· Repeatable location accuracy…±0.01mm
All kind of movement patterns are repeatable by driving the pump input shaft in bi-directions in combination with sensors.
Actual Application
Injection Molding Machine
- Accurate control of thrust force by Hydraulics, which was not possible by electric ball screw.
- The whole system becomes simpler, lower cost, and energy saving.
Sumitomo（SHI）DEMAG SE-EV series
Robotics
- High power, high precision robot is possible with the combination of advantage of hydraulic and electric.
- Possible to set in a small space thank to the compact size.
Exsoskeleton by BIA
High power, compact pump is necessary to carry the total weight of the exsoskeleton and a human.
Ankle foot orthosis by CCEFP
Total weight 3.3kg. The weight of the device on ankle part where the exercise load is big is reduced to 0.97kg by wearing the power supply on the waist. 65Nm torque is generated by Takako's standard 0.4cc pump.
