1. Exhaust throttle valve: Yes/No

2. Shut-off or throttle valve with a rotating flap

3. Device for adjusting the throttle valve of internal combustion engines

4. The direct drive for a throttle valve shaft (7) in a throttle valve manifold (8) comprises a coil (1) and a rotor (2) arranged directly adjacent to the coil (1).

5. Method for producing a throttle valve in a continuous throttle body by plastic injection molding

6. A throttle valve is attached to a first shaft (18) and rotates to regulate air intake.

7. A disk turning on a diametrical axis inside a pipe, used as a throttle valve or damper.

8. Throttle valve for regulating the amount of intake air in an internal combustion engine and process for producing the same

9. The invention relates to a method and a device for actuating a setting element, especially for adjusting a throttle valve in the induction tract of an internal combustion engine.

10. Furthermore, if the occurrence of the acceleration slip is anticipated, the opening of the sub-throttle valve (12) is in advance set to the stand-by opening $g(U)ss suitable for suppressing the acceleration slip.

11. A table of boost setpoints and spark advance and retard timings are stored in memory and are addressed as a function of the position of the throttle valve (36) and the speed (70) of the engine.

12. A fuel economy driving guide system for tractors according to the present invention comprises: a speedometer for detecting the speed of a tractor; a potentiometer for detecting the opening angle of a throttle valve of the tractor; a GPS sensor for detecting the operational velocity of the tractor; an input device for inputting information; a monitor for displaying the information; and a controller.
