Abstract (en)
[origin: EP1391590A1] If an internal combustion engine is mounted in a vehicle or machine which is operated at an extreme inclination or rolls over, there is a risk that substantial quantities of oil can flow under gravity through the engine breather system and enter the engine induction system. This can cause the engine to run in an ungoverned condition and can result in damage to the engine as well as undesirable engine emissions. The invention provides a breather shut-off valve including a valve chamber and a float movably held within the valve chamber. The valve chamber has a floor, a side wall provided with an inlet aperture, and a roof provided with an exit aperture. The float is adapted to move between a first position in which the exit aperture is open when the valve chamber has no oil or other liquid therein and a second floating position in which the exit aperture is closed by the float when the valve chamber has oil or other liquid therein. The breather shut-off valve is compact in height and can be used with a known pressure regulation valve. <IMAGE>
