ABSTRACT:
A lubrication system for an air motor which incorporates a positive feed oil pump, driven by the air motor, which forces lubricant, under pressure to the majority of critical lubrication zones. Because of manufacturing tolerances as well as ease of maintenance, the rotary valve and the main crankshaft are coaxial but separate. The lubricant is forced inwardly to the axis of either the crankshaft or the rotary valve and then transmitted to the other rotating member by way of a hollow elastic snubber which preloads the valve and crankshaft in opposite directions.
