Title: Piston driving device using hydrogen absorbing alloy
Inventor: ODAI YASUO
IPC: F15B21/06
Filed: 1986-11-06
Abstract: PURPOSE:To increase the response speed of a piston and reduce driving energy for a piston by heating and cooling the hydrogen occluding alloy of the piston driving device by means of thermomodules. CONSTITUTION:Reaction vessels 6 having hydrogen occluding alloy in their insides are provided in a piston 2 with thermomodules 7 put between them. When an electric current is fed through the thermomodule 7 in such direction that its left side may generate heat, and its right side may absorb the heat, the reaction vessel 6 being in contact with the left side is heated to cause the hydrogen occluding alloy in its inside to emit hydrogen gas, and the piston 2 is therefore pressed to the right to move. When the electric current is fed through the thermomodule 7 in a direction opposite to the above one, the piston 2 is pressed to the left to move. Thus the piston 2 can he moved at quick response speed, and driving energy for a piston driving device can be also reduced.
