Bypass Valve Applied to the Electro-Hydraulic Actuator (EHA)

  • Technology Readiness Level: 3 (Experimental proof of concept )
  • Technology Validation: This technology has been validated through laboratory testing and computer modelling.

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.
