Kato, H

A blow-by gas recirculating apparatus for returning blow-by gases from the crankcase of an internal combustion engine to an intake passage thereof is described comprising: a cylinder head; a cylinder head cover mounted on the engine cylinder head; a DOHC valve mechanism housed in the cylinder head; a shield panel attached to the cylinder head cover in substantially covering relation to the DOHC valve mechanism; a breather chamber defined between the cylinder head cover and the shield panel and communicating with both the interior of the cylinder head and an air intake unit of the internal combustion engine; the breather chamber extending longitudinally of the cylinder head cover and comprising a central first, second and third chamber sections each extending longitudinally substantially the full length of the cylinder head; and the second and third breather chamber sections being located one on each side of the first breather chamber section, the first through third breather chamber sections being interconnected by passages for causing blow-by gas passing from the interior of the cylinder head to flow longitudinally for substantially the entire length of the cylinder head cover through each of the first, second and third breather chambers, in that order, to the intake unit of the internal combustion engine.
