Abstract
An electric motor and an in-line speed-responsive clutch are arranged so as to provide dual drive for selectively driving a refrigerant compressor by either an internal combustion engine or by the electric motor. The rotor of the electric motor is journalled for relative rotation on the output shaft of the engine, and the motor rotor can be driven through the clutch when the output speed of the engine output shaft exceeds a predetermined minimum. By having both power sources adapted to drive the compressor with the motor rotor journalled on the engine output shaft and by employing a single clutch, economy of parts, relative ease in assembly, and a more compact arrangement may be achieved.
