Abstract
Viene descritto un sistema di sfiato dei vapori di olio dal carter di motori a combustione interna, del tipo comprendente una testata (10) fissata ad un basamento motore o carter (11) mediante bulloni di fissaggio (12) infilati attraverso corrispondenti passaggi (13) ottenuti nel corpo della testata (10) e quindi serrati in apposite sedi filettate (14) ricavate nel basamento (11). Almeno parte dei passaggi (13) sono ricavati paralleli ad una serie di ulteriori passaggi cilindrici verticali (17,18) ricavati attraverso la testata (10) e il carter (11) per la ricaduta dell'olio (19) che condensa nella testata (11).Almeno un passaggio (18) di ricaduta dell'olio è posto in comunicazione con uno dei passaggi (13) dei bulloni di fissaggio (12) per mezzo di un condotto di collegamento (20) ricavato nel corpo della testata (10).A system for venting oil vapors from the crankcase of internal combustion engines, of the type comprising a head (10) fixed to an engine base or crankcase (11) by means of fixing bolts (12) inserted through corresponding passages (13), is described obtained in the head body (10) and then tightened in special threaded seats (14) obtained in the base (11). At least part of the passages (13) are obtained parallel to a series of further vertical cylindrical passages (17,18) obtained through the head (10) and the casing (11) for the relapse of the oil (19) which condenses in the head ( At least one oil return passage (18) is placed in communication with one of the passages (13) of the fixing bolts (12) by means of a connection conduit (20) obtained in the head body (10) .
