ABSTRACT:
A prime mover has a rotatable shaft with an exterior end section thereof adapted for driving an apparatus and for subjection to leakage flow from the apparatus of a fluid incompatible with a lubricant of a lubrication system in the prime mover to effect the lubrication of the shaft. An end plate on the prime mover has an opening extending therethrough in radially spaced relation with the shaft and communicating with the lubrication system, and means is provided for preventing the passage of the fluid and the lubricant through the opening. The passage preventing means includes means disposed at least in part within the opening and arranged about the shaft for conjoint rotation therewith, means integral with the conjoint rotation means for interrupting any flow of the lubricant on the shaft and generally therealong toward the opening and for returning the interrupted lubricant to the lubrication system, and means on the conjoint rotation means for interrupting the fluid in the event of any leakage thereof generally along the exterior section of the shaft toward the end plate and displacing the interrupted fluid away from the opening.
