ABSTRACT:
A portable drive unit for a valve actuator includes a portable two-cycle or four-cycle gasoline engine and a gear reducer. The gasoline engine is bolted, through vibration damper means, to the housing or gear box of the gear reducer. The gear box is clamped to the valve actuator through an annular clamp and clamp-receiving adapter structure which also includes vibration damper means. A flexible sleeve coupling in the bore of the annular clamp and clamp-receiving adapter couples the output shaft of the gear reducer to the handwheel input shaft of the valve actuator.
