Definitions

  • the invention relates to a throttle valve assembly for an internal combustion engine, which has a throttle valve which can be pivoted by means of an actuating shaft guided through an actuating shaft passage in the throttle valve assembly.
  • throttle valve connectors are provided in the internal combustion engines of today's motor vehicles and are generally known.
  • the idle speed is not simply set to a certain value with an average load, but is regulated by means of an electronic controller to a setpoint value which is only slightly above the running limit of the engine in all load conditions. This reduces fuel consumption and the environmental impact of harmful exhaust gas.
  • the invention has for its object to design a throttle body of the type mentioned in such a way that with small opening angles, a sensitive control of the air flow rate is possible by adjusting the throttle valve.
  • This object is achieved in that in the edge region of the throttle valve, a spreading body which is movable out of the throttle valve edge when the throttle valve is opened as a function of the angular position of the throttle valve is arranged.
  • This simple design of the throttle valve body changes the surface of the throttle valve which throttles the cross-section of the throttle valve body when the throttle valve is pivoted.
  • the undesirable effect that occurs with previous throttle valves, that the free cross section increases significantly even at small opening angles, is avoided in that, thanks to the invention, the throttle valve increases in cross section at small opening angles compared to its closed position.
  • This design of a throttle valve eliminates the need for a bypass with an idle actuator as an actuator for idle control.
  • the throttle valve assembly according to the invention is particularly simple if the expansion body is a spring sleeve which, with two curved pieces which can be moved out of the throttle valve edge, bears against a footprint of the housing of the throttle valve assembly.
  • the footprint can also be generated very easily if it is provided coaxially with the control shaft passage on the inside in the throttle valve connector.
  • the expansion body is simple and easy to attach to the throttle valve if, according to a further advantageous embodiment of the invention, it consists of an inner, non-closed ring body fastened to the throttle valve, from the free ends of which ring bodies two expansion body arms extend radially outwards, on which one of the arc pieces running along the edge of the throttle valve and abutting the footprint is connected.
  • the expansion body has a different cross section over its circumference.
  • the bending line of the expansion body can be used in the desired manner to determine how the expansion body deforms when the throttle valve is pivoted and thus moves outward when the throttle valve is opened.
  • the throttle valve assembly shown in FIG. 1 has a throttle valve 2 in a housing 1, which is held by an actuating shaft 3 which is guided through an actuating shaft passage 4 of the housing 1.
  • a spreading body 5 designed as a spring sleeve, which rests with the ends of two curved pieces 6, 7 against a mounting surface 8 which surrounds the control shaft passage 4 and is provided on the inside of the housing 1 coaxially with the control shaft 3.
  • This footprint 8 is designed so that the arc pieces 6, 7 are spread with an initial pivoting movement of the throttle valve 2 and thereby move radially outward similar to the brake shoes of a drum brake.
  • FIG. 2 shows that the throttle valve 2 is formed from two outer disks 9, 10, which are kept at a distance by a center piece 11.
  • the expansion body 5 is arranged between these outer disks 9, 10. Shown in Figure 2 is also the footprint 8 through which the expansion body 5 is spread so that it can increase the area of the throttle valve 2 when the throttle valve 2 is pivoted in the opening direction.
  • the feed body 5 can be designed very differently, for example from two individual, semicircular arc pieces 6, 7, which are fastened to the throttle valve 2 on the side opposite the positioning surface 4.
  • FIG. 3 shows a special embodiment of the expansion body 5, which has a ring body 12 that is not closed.
  • This ring body 12 has two radially inward projections 13, 14, which serve to prevent it from rotating on the throttle valve 2. From the free ends of the ring body 12, two spreader arms 15, 16 lead radially outward, to which the curved pieces 6, 7 adjoin, which in turn rest with their free ends against the footprint 8 shown in the previous figures.
