FIELD: mechanical engineering. SUBSTANCE: drive comprises fixed support 1, movable support 2 constructed as a rod with thrust flanges 3,4 on faces, working 6 and reverse 7 members made of material with heat-mechanical memory, and means 10 for heating members 6. The rod passes through opening 5 provided in support 1. Member 7 are arranged on different sides of support 1 and encloses support 2. Members 6,7 is made of monocrystals of a copper based alloy, constructed as straight rods and set in races 8,9. The total cross-section of members 6 is grater than the total cross-section of members 7. The temperature, at which the length of members 7 is recovered, is lower than the temperature for members 6 and higher than ambient temperature. EFFECT: enhanced efficiency. 3 dwg
