THERMO-MECHANICAL POWER DRIVE

摘要

FIELD: machine building. ^ SUBSTANCE: drive is designed for system of thermo-regulation and for small-size drives. The drive consists of a case wherein a rod with a piston is installed. The piston divides a cavity of the case in two thermo-insulated chambers. A set of cylinder springs is arranged in each chamber. The set consists of two springs of a smaller and bigger diametre; also springs of smaller diametre are inserted into springs of bigger diametre. All springs are made out of thermo-sensitive alloy with a shape memory effect. In the initial position the springs are compressed in one chamber, while they are stretched in the other. Each chamber is equipped with electro-magnetic valves for inlet and outlet of cold or hot water or another liquid depending on temperature of martensite transformations of thermo-sensitive alloy of springs. ^ EFFECT: reduced weight-dimension characteristics. ^ 3 cl, 2 dwg
