Embodiment 1
[0013] Example 1, please refer to Figure 1 to Figure 2 , as shown in the figure, a bellows assembly for an automobile idle valve includes a cover plate 1, a tube body 2 arranged at the lower end of the hole in the cover plate 1, and a base 3 integrally formed with the tube body 2. The pipe body 2 is a pipe body with a corrugated outer wall, the base 3 is provided with a central hole 4 through the inside and outside, and the base 3 is also provided with a group of through holes 5 around the central hole 4; preferably, the pipe body 2 and The base 3 is made of polytetrafluoroethylene; preferably, there are four through holes 5 , and the through holes 5 are arranged around the central hole 4 in a square shape.
[0014] On the one hand, a central hole 4 is set on the base 3 to engage with the valve stem of the idle valve, and the bellows assembly moves up and down under the drive of the valve stem to realize the opening or closing of the valve; on the other hand, a center hole 4 ...

The invention discloses a corrugated pipe assembly for an idle valve of an automobile. The corrugated pipe assembly comprises a cover plate, a pipe body arranged at the lower end of a cover plate middle hole and a base integrally formed with the pipe body, wherein the pipe body is provided with a corrugated outer wall, and a center hole penetrating the inside and the outside and a group of through holes located on the periphery of the center hole are formed in the base. According to the corrugated pipe assembly, the cover plate and the base are connected into a whole through the pipe body, the group of the through holes are formed in the base, and an internal passage of the pipe body is communicated with an intake manifold of an engine through an air inlet end of the idle valve, and the structure is adopted, so that the corrugated pipe assembly can produce differential pressure between the inner wall and the outer wall according to the change of the vacuum degree of the intake manifold of the engine, and different expansion degrees are produced for adjusting the opening degree of the valve in real time.
Description
technical field [0001] The invention relates to an automobile idle speed valve component, in particular to a bellows assembly used for the automobile idle speed valve. Background technique [0002] The idle speed valve is installed on the bypass air hole of the throttle body, and the speed is adjusted by controlling the air volume of the bypass throttle body. The idle speed controller will control the idle speed when the engine speed is lower than 750rpm (rev / min) according to the ignition signal. The valve acts to increase the engine speed. After the engine speed exceeds 1050rpm (revolutions per minute), the idle valve stops acting. At present, the most widely used in the world is the stepper motor type idle speed valve, which includes a rotor composed of permanent magnets, a stator composed of excitation coils, and a feed screw and valve that convert rotary motion into linear motion. The signal is converted and controlled, so that the rotor can rotate forward or reverse, ...
