Abstract

A crankcase scavenging mechanism for a four-stroke engine is disclosed. A valve operating chamber (5) is assembled from a cylinder head and a cylinder head cover (3) and is communicated with a crankcase (6). The cylinder head cover (3) is arranged on the top of the cylinder head (9) and is provided with a gas-oil separating cavity (23) on the top thereof. A passage (37) is communicated with the valve operating chamber (5). The gas-oil separating cavity (23) is connected with a partition plate (25) to form an oil-gas separation chamber (26). The oil-gas separation chamber (26) is provided with a one-way valve (27) thereon. The one-way valve (27) is installed in a one-way valve hole (28). A passage (33) above the one-way valve (27) is provided with an inclined orifice (38), one end of which is blocked by a plug (39), the other end of which is communicated with the cylinder head (9) and is further communicated with a suction tube (14) through a cylinder head communication passage (41). An oil-returning hole (34) is formed between the inclined orifice (38) of the passage (33) and the oil-gas separation chamber (26).
