Wherein, the epimere of return elastic component and hypomere are respectively the shape of threads elastic ring of some steel wires moulding around the home, angle is the extended leg that extend towards the outside at the starting point place of epimere shape of threads elastic ring, it is " U " font haptic element that epimere and hypomere joining place extend towards the outside that throttle blade is closed return pin, and it is the extension haptic element that hypomere shape of threads elastic ring end extends towards the outside that throttle blade is opened return pin; Described tooth sector is provided with the positioning convex and the limiting stopper that extend towards throttle blade, and described throttle blade is closed return pin and can be conflicted or separate with positioning convex, and throttle blade unlatching return pin and limiting stopper are all the time in conflict state.
Adopt technique scheme, tooth sector is the STATEMENT OF FEDERALLY SPONSORED linking with the drive motor middle gear of closure, between throttle plate pin and tooth sector, the setting of return elastic component makes the throttle blade on throttle plate pin can obtain return (being the initial position of closure) fast after opening or closing, and this return elastic component is made up of epimere and hypomere, the setting of angle is in order to make return elastic component keep location with the housing of closure, throttle blade is unlocked and completes after the work of unlatching, can be subject to the elastic force of epimere shape of threads elastic ring, make throttle blade be returned to initial position, now active force is that throttle blade closes on return pin, in the time that the elastic force that is subject to epimere shape of threads elastic ring when throttle blade returns back to the position of close the throttle air passageways, throttle blade closes return pin and positioning convex is conflicted, throttle blade is shut down, throttle blade open return pin all the time with tooth sector on limiting stopper keep conflicting, in the time that throttle blade is completely in the closed position by air passageways, the active force that can be subject to hypomere shape of threads elastic ring is opened throttle blade and air passageways slightly, air still can be entered by air passageways, arrange so simple in structure, easy for installation.
The utility model is further set to: the mounting end of throttle plate pin and drive end place are arranged with respectively oil-impregnated bearing.
Adopt technique scheme, arrange and make throttle plate pin more stable in rotary course like this, and be difficult for being worn, extend its working life.
Below in conjunction with accompanying drawing, the utility model is further described.
