Function introduction of throttle body.
An electronic throttle valve belongs to a throttle valve part of an air intake system of an automobile engine.
It comprises a throttle body, a throttle valve plate, a throttle shaft, a DC motor, a gear reduction mechanism and a torsion spring, wherein one end of the torsion spring is fixed on the throttle body, and the other end is fixed on a gear of the throttle shaft.
There is also an idle speed adjustment device:
The outer adjusting screw is screwed on the throttle body, the inner adjusting screw is screwed on the inner cavity of the outer adjusting screw, the ejector pin is located in the inner cavity of the outer adjusting screw and has a shoulder, the outer end of the ejector pin in front of the shoulder extends out of the opening of the outer adjusting screw, and the spring abuts between the shoulder of the ejector pin and the inner adjusting screw.
The outer end of the ejector pin abuts against the gear of the throttle shaft, so that the throttle plate is in a slightly static position when there is no motor drive. The invention can adjust the high and low idle positions, accurately control the air intake of the engine under the idle working condition, and reduce the manufacturing accuracy.
