ABSTRACT:
Improved lubricant control assemblies are disclosed for reciprocating piston rods of an engine which prevent crankcase lubricant intruding into the cylinders and fluid from the cylinders from escaping into the crankcase. Each assembly comprises a tubular sleeve fitting closely onto a piston rod and yieldably mounted within the bore between cylinder and crankcase through which the piston rod extends. The sleeve is urged into forceful contact around the piston rod by a plurality of disk members which forcefully urge the sleeve in contact around the piston and for controlling lubrication.
