THERMOBIMETALLIC DRIVE Russian patent published in 1995 - IPC

FIELD: instrument engineering. SUBSTANCE: thermobimetallic drive is composed of a set of deformable members series-connected to each other. Each deformable member comprises a bimetallic disk non-bimetallic housing attached to each other around external contour. The bimetallic disk is composed of two plates coupled with each other one of which is circular and is disposed inside the other circular-shaped plate. Active and passive layers of different plates are located oppositely. An inner radius of the circular plate is 0.65 of its outer radius. The deformable members are coupled such that central portion of bimetallic plate of one member is coupled with the housing of the following one. EFFECT: enhanced reliability. 2 dwg
