Claims8
A cylinder head for an internal combustion engine, said cylinder head comprising:
- (a) a housing having a top surface, a bottom surface, a first side surface, an air inlet opening at said first side surface, an air outlet opening at said bottom surface of said housing, and an air inlet cavity extending from said air inlet opening to said air outlet opening;
- (b) a dividing wall extending from said air inlet opening to a terminal end at said air outlet opening, said dividing wall dividing said air inlet cavity into a first channel and a second channel;
- (c) a poppet valve having a head portion at said air outlet opening and a stem portion that extends from said head portion through said dividing wall, said stem portion being located in the same plane as said dividing wall and being slidably mounted in said dividing wall and said housing, said poppet valve being movable between an open position in which said head portion is below said air outlet opening and a closed position in which said head portion is below the terminal end of said dividing wall and in a closing relationship with said air outlet opening.
A cylinder head for an internal combustion engine, said cylinder head comprising:
- (a) a housing having a top surface, a bottom surface and a first side surface, an air outlet opening at said bottom side, a first air inlet opening at said side surface, a second air inlet opening at said side surface, a first air inlet channel extending from said first air inlet opening to said air outlet opening and a second air inlet channel extending from said second air inlet opening to said air outlet opening;
- (b) a poppet valve having a head portion at said air outlet opening and a stem portion that extends between said first air channel and said second air channel and being mounted for axial movement in said housing between an open position in which said head portion is below and spaced from said air outlet opening and a closed position in which said head portion is at said air outlet opening for closing said air outlet opening.
A cylinder head for an internal combustion engine, said cylinder head comprising:
- (a) a housing having a top surface, a bottom surface, a first side surface, an air inlet opening at said first side surface, an air outlet opening at said bottom surface of said housing, and an air inlet cavity extending from said air inlet opening to said outlet opening;
- (b) a poppet valve having a head portion at said air outlet opening and a stem portion that extends from said head portion through said air inlet cavity and said top surface, said stem portion being mounted in said head for movement between an open position in which said head portion is below said air outlet opening and a closed position in which said air outlet opening is closed by said head portion;
- (c) a dividing wall extending from said air inlet opening to said poppet valve for dividing said air inlet cavity into a first channel that has a first exit opening at a first side of said poppet valve and a second channel that has a second exit opening at a second side of said poppet valve opposite said first side;
- and
- (d) a sleeve mounted in said housing and extending into said air inlet cavity, said stem portion being slidably mounted within said sleeve, said dividing wall abutting said sleeve and extending to said stem portion and to said head portion when said poppet valve is in the closed position.
