Abstract
A compact thermoelastic actuator includes at least two identical force pieces and a securing piece, the securing piece having a coefficient of thermal expansion less than the coefficient of thermal expansion of the force pieces. The force pieces are mounted head-to-tail one beside the other parallel to a longitudinal axis Y and are linearly offset relative to one another, along the longitudinal axis Y. The securing piece has two ends respectively linked to external ends of each force piece and internal ends of each force piece are positioned under a median region of the securing piece. The actuator and device is applicable to waveguides of multiplexers incorporated in space equipment for satellites.
