FITTED CRANKCASE BREATHER VALVE ASSEMBLY

摘要

A crankcase breather assembly for an internal combustion engine. A breather passage is provided in the crankcase for communication of combustion gases out from the crankcase interior and includes an annular recess defining a shoulder having a corner edge. A valve assembly is disposed in the passage for intermittently permitting the expulsion of gases from the crankcase interior through the passage. The valve assembly includes a valve seat portion connected with a flexible breather valve. The valve seat portion includes a locking portion disposed at least partially within the annular recess and forms an interference fit therein, and extending axially beyond the corner edge such that the corner edge positively locks the valve seat within the passage.
