Abstract
PURPOSE:To enable the effect of fluctuation in intake air to be eliminated by arranging a valve body energized by springs to the direction of a pressure detector in a pressure introduction pipe where the plugging of an air cleaner is detected by connecting the pressure detector to the pressure introduction pipe extended from an intake pipe. CONSTITUTION:Pressure introduction pipes 2a and 2b are extended from an intake pipe 4 at the down-stream side and the up-stream side of an air cleaner 3 respectively for allowing a pressure detecting section 1 to be connected. The aforesaid pressure detecting section 1 is equipped with a cylindrical holding member 13 at the center of the inner cylinder of a main body housing 11 in a form of a double cylinder so as to let the aforesaid holding section 13 hold a semi-conductor pressure sensing chip 14 in such a way that the inner cylinder is crossed over thereby at its center, and is also so constituted that the valve bodies 6a and 6b energized by coil springs 5a and 5b are arranged at the right and left inner cylinders of the holding member 13. And the opening/closing motion of the valve bodies 6a and 6b interlocked with the fluctuation of exhaust gas thereby allows the fluctuation of exhaust gas to be rectified, and when the difference in negative pressure within the intake pipe between the up-stream side and the down-stream side exceeds a preset value, the detection thereof is made by the pressure sensing chip 14 for letting a warning light for plugging be lighted.
