Abstract (en)
[origin: WO2007000058A1] A metal hydride actuator comprising a pressure chamber having a first and second pressure chamber portions and at least one reaction chamber operatively connected to one of the first and second pressure chamber portions, the at least one reaction chamber having a temperature adjustment mechanism and containing therein metal hydride powder. A piston is positioned in the pressure chamber, the piston forming a barrier between the first and second pressure chamber portions, and a movement transmission means is operatively connected to the piston, the movement transmission means being so positioned in the first pressure chamber portion as to exit from an opening in a wall of the first pressure chamber portion. The temperature adjustment mechanism may be used to cause a change of temperature of the metal hydride powder in at least one of the reaction chamber, thereby creating a pressure differential between both pressure chamber portions, causing the piston to move.
