Abstract
A drive system for a blower, forming part of an external heating circuit of a Stirling engine, is disclosed. A viscous-shear coupling is arranged with the input member thereof concentrically surrounding a one-way clutch which in turn is mounted on an accessory shaft extending through the assembly. The drive system is effective to operate only after the engine has reached predetermined thermal operating conditions; a power transfer is made from an auxiliary blow motor drive to said system upon reaching said conditions.
