Definitions

  • This arrangement provides means by which the positioning and orientation of the inlet and outlet pipes relative to the engine, can easily be altered by relative movement of the throttle body, air horn and/or manifold to meet the requirements of the layout for the throttle mechanism relative to the engine.
  • a throttle mechanism 10 in accordance with the present invention is shown, and comprises a throttle body 12, a shaft 14, a flap valve 16 of the flat butterfly type, and means for rotating the shaft in the form of a lever arm 18 and throttle linkage 20.
  • Other forms of rotating means such as a DC electric motor, cable, cam or simple lever and stud, may be used.
  • the throttle body 12, in use, is secured between a manifold 22 ( Figure 2) and an air horn 24 ( Figure 3).
  • the manifold 22 is attached to an engine of a motor vehicle, as is well known to those skilled in the art, and an air filter can be mounted on the opposite side of the air horn 24 to the throttle body 12 usually via a separate duct from a remote air filter housing.
  • the other end of the shaft 14 also extends beyond the outer wall 40 and is associated with the throttle position sensor 26.
  • the flap valve 16 is secured to the shaft 14 (by screws 44 or any other suitable means) and can move (on rotation of the shaft) between a fully open position, in which the flap valve forms virtually no restriction on the flow of air/fuel through the bore 38, and a substantially closed position in which the flap valve substantially closes the bore for idle operation of the engine.
  • This arrangement allows easy formation of the idle air passage without the need for subsequent plugging of bores in the throttle body.
  • the idle air control valve seat is shown as being formed separately from the throttle body, it could be formed integrally with the throttle body.

Claims (7)

  1. Drosselmechanismus (10) für einen Motor eines Kraftfahrzeuges wobei der Mechanismus umfaßt: einen Luftstutzen und/oder einen Krümmer; einen Drosselkörper (12), der zwischen dem Luftstutzen (24) und dem Krümmer (22) befestigt sein kann und eine Innenwand (36), die eine sich durch diesen erstreckende Bohrung (38) festlegt, wobei die Bohrung eine Längsachse (X) aufweist, eine Außenwand, eine erste Oberfläche (98), die mit dem Luftstutzen verbindbar ist, und eine zweite Oberfläche (98') aufweist, die mit dem Krümmer verbindbar ist, wobei die erste und die zweite Oberfläche planar und im wesentlichen parallel zueinander sind; eine Welle (14), die sich über die Bohrung hinweg erstreckt und eine Längsachse (Y) aufweist, die im wesentlichen senkrecht zur Längsachse der Bohrung steht, wobei die Welle in der Innenwand des Drosselkörpers für eine Schwenkbewegung um die Längsachse der Welle herum drehbar angebracht ist, wobei mindestens ein Ende (42) der Welle durch die Innenwand verläuft, so daß sie sich über die Außenwand hinaus erstreckt; ein Klappenventil (16), das an der Welle innerhalb der Bohrung zur Bewegung zwischen einer vollständig offenen Position und einer im wesentlichen geschlossenen Position bei einer Drehung der Welle befestigt ist; und Fluiderwärmungsmittel;
    gekennzeichnet,
    durch ein Mittel (18, 20), das an dem mindestens einen Ende der Welle benachbart zur Außenwand befestigt ist, um die Welle zu drehen; und dadurch, daß die Fluiderwärmungsmittel (34) eine Ausnehmung (96), die in der ersten Oberfläche gebildet ist, eine im wesentlichen identische Ausnehmung (96'), die in der zweiten Oberfläche gebildet ist, und ein Einlaßrohr (104) und ein Auslaßrohr (106) umfassen, die an dem Luftstutzen oder dem Krümmer angebracht sind und über Fluid mit einer der Ausnehmungen mittels Bohrungen (100, 102) verbunden sind, die durch den Luftstutzen oder den Krümmer verlaufen, so daß Fluid durch das Einlaßrohr in die Ausnehmung und durch das Auslaßrohr heraus strömen kann.
  2. Drosselmechanismus nach Anspruch 1, wobei das Einlaßrohr (104) und das Auslaßrohr (106) an dem Luftstutzen (24) angebracht sind.
  3. Drosselmechanismus nach Anspruch 2, wobei das Einlaßrohr (104), das Auslaßrohr (106) und der Luftstutzen (24) integral in einem Stück gebildet sind.
  4. Drosselmechanismus nach Anspruch 1, wobei das Einlaßrohr und das Auslaßrohr an dem Krümmer angebracht sind.
  5. Drosselmechanismus nach Anspruch 4, wobei das Einlaßrohr, das Auslaßrohr und der Krümmer integral in einem Stück gebildet sind.
  6. Drosselmechanismus nach einem der Ansprüche 1 bis 5, wobei die Ausnehmungen (96, 96') fluidisch voneinander isoliert sind.
  7. Drosselmechanismus nach einem der Ansprüche 1 bis 6, wobei Vakuumanschlüsse (32) durch den Luftstutzen oder den Krümmer verlaufen.
