COMPACT THERMOELASTIC WAVEGUIDE ACTUATOR, WAVEGUIDE WITH PHASE STABILITY AND MULTIPLEXER WITH SUCH ACTUATOR Russian patent published in 2016 - IPC H01P3/00 H01P3/12 H01P1/30 

FIELD: engines and pumps.

SUBSTANCE: invention relates to waveguides of multiplexers built in the satellites of space equipment. Claimed thermoelastic actuator (15) comprises at least two identical reinforcing parts (10a-10d) and the retainer (11). Note here that the latter features the thermal expansion factor lower than that of the reinforcing parts. Said reinforcing parts (10a-10d) are arranged nearby to face each other in opposite sides in parallel with the lengthwise axis Y and linearly shifted relative to each other there along. The retainer (11) comprises two ends connected with the outer ends of every reinforcing part while the inner ends thereof are located above the medium zone (14) of the part (11).

EFFECT: compact and simplified design.
