An apparatus includes a valve member configured to be reciprocatably disposed within a valve pocket defined by an interior surface of a cylinder head. The valve member has a tapered portion defining multiple flow passages and including multiple sealing portions. At least one sealing portion is disposed adjacent each flow passage and is configured to contact a portion of the interior surface of the cylinder head such that each flow passage is configured to be fluidically isolated from an area outside of the cylinder head.

La présente invention vise un appareil comprenant un organe de soupape configuré pour être disposé de façon à permettre un va-et-vient à l~intérieur d~une coupelle de soupape définie par une surface intérieure de culasse. L~organe de soupape a une partie effilée qui définit de multiples passages d~écoulement et comprend de multiples parties d~étanchéisation. Au moins une partie d~étanchéisation est disposée à côté de chaque passage d~écoulement et est configurée pour entrer en contact avec une partie de la surface intérieure de la culasse de façon à ce que chaque passage d~écoulement soit configuré pour être isolé, du point de vue des fluides, d~une zone à l~extérieur de la culasse.
