Lubricating system for a vertical internal combustion engine.

摘要

A lawn mower or other similar walk behind type of implement that is designed to be operated in a normally erect position and which is tilted to its side for servicing. An engine is provided for the lawn mower having an output shaft rotatable about a vertically extending axis. The engine includes a lubricating system incorporating a crankcase in which the engine output shaft rotates and a crankcase ventilating system. The crankcase ventilating system is designed so as to prevent lubricant from flowing into the induction system when the engine is tilted on its side.
