In a collaboration between Saab AB and Linköping University a new type of cylinder with releasable piston is under development, which allows the change of the piston area in discrete steps during operation.
The innovation, Hydraulic Infinite Linear Actuator (HILA), makes it possible to control the speed and power energy efficiently. The innovation is flexible, modular, compact, leak-proof and offers high piston rod speeds. HILA technology creates new uses for hydraulic cylinders, thanks to the very long stroke lengths are allowed, in many application areas. The technology has great industrial potential and contribute to sustainable growth and the conversion of the energy system. The primary functions of the HILA technology have been verified with very good results in 2015. In this subsequent project a demonstrator of the innovation will be tested in a relevant environment, eq. TRL 5-6.
