Abstract:
In a breather device of an internal combustion engine, a breather chamber is defined by a head cover main body and a chamber forming member. The breather device includes an upstream breather passage communicating a first end of the breather chamber with a crank chamber, a downstream breather passage communicating a second end of the breather chamber with an intake passage, an oil return passage formed in a cylinder head to communicate a valve actuation chamber with the crank chamber, a first communication hole formed in a lower part of a recessed part of the breather chamber adjoining the first end of the breather chamber to communicate the breather chamber with the valve actuation chamber, and a second communication hole formed in a part of the breather chamber downstream of the first communication hole to communicate the breather chamber with the valve actuation chamber.

Claim (Index 12):
The breather device according to  claim 1 , wherein the breather chamber includes a first gas liquid separation chamber extending from the first end in the cylinder row direction, and a second gas liquid separation chamber having one end connected to an end of the first gas liquid separation chamber remote from the first end via a PCV valve and extending from the one end thereof to the second end of the breather chamber in parallel with the first gas liquid separation chamber, the first communication hole and the second communication hole communicating the first gas liquid separation chamber with the valve actuation chamber.
