Increasing interest in the replacement of traditional hydraulic architectures with energy-efficient, plug-and-play systems has led to great potential for electro-hydraulic actuator (EHA) technology. Current EHAs have a wide range of applications within mechanical systems, but they are often limited by overall efficiency as well as the range of functional actuation speeds. Researchers at Purdue University have developed a concept for an improved EHA system that increases efficiency and range of actuation speeds while decreasing cost and size of the EHA unit. This concept represents a step forward for the application of EHAs in place of their traditional hydraulic counterparts.

Advantages:
- More compact than existing solutions
- Lower cost than existing solutions
- Increased efficiency and energy recuperation
- Improved range of actuation speeds using a fix-displacement pump

Applications:
- Heavy duty mobile machinery
- Aerospace
- Robotics
- Prosthetics

Technology Validation:
This technology has been validated through laboratory testing and computer modelling.
