Abstract

See full text

An engine body includes a crankcase with a crank chamber therein, a cylinder block attached to the crankcase, and a breather passage which selectively permits fluid communication between the crank chamber and an area outside of the crank chamber. The engine body includes a one-way valve between the crank chamber and the breather passage, which allows a one-way flow of gases from the crank chamber to the breather passage. The one-way valve is pressure-operated and is operatively attached to a side wall of the engine body proximate a cylinder sleeve. The one-way valve may be mounted in a mounting window in a side wall of the crankcase, and a timing chamber may function as the breather passage. In an illustrative embodiment, the one-way valve includes a base plate having a valve hole formed therein, and a flexible reed valve plate with one end affixed to the base plate.
