ABSTRACT:
The object of the present invention is a seal device for a valve rod controlled by a cam included in a camshaft housing of an internal-combustion engine having at least one cylinder.
The device according to the invention includes a pipe (10) connecting on the one hand a feed line (2) for feeding the carbureted mixture into a combustion chamber (1) closed by a valve (5) and, on the other hand, a camshaft housing (4). A nonreturn valve (11) is arranged in said pipe (10) in order to divide said pipe (10) into two volumes (12, 13), the first volume (12) being connected to housing (4) and forming a capacity under pressure having a pressure P1 greater than or equal to the pressure P2 prevailing in feed line (2) and in the second volume (13).
The device according to the invention is intended for preventing fuel leaks from the feed line (2) towards the camshaft housing (4).
