PULSATION DECREASING DEVICE

PURPOSE:To reduce the cost and space of a device for decreasing pulsation in a pipeline and to realize high responsiveness. CONSTITUTION:The pulsation of the same frequency as the pulsating frequency of the pulsating flow in the pipeline 1 is oscillated by an oscillation section 6. On the other hand...

Beschreibung
Zusammenfassung:	PURPOSE:To reduce the cost and space of a device for decreasing pulsation in a pipeline and to realize high responsiveness. CONSTITUTION:The pulsation of the same frequency as the pulsating frequency of the pulsating flow in the pipeline 1 is oscillated by an oscillation section 6. On the other hand, a resonance section 7 is communicated with this oscillation section 6 as well and resonates and vibrations the pulsation generated by the oscillation section 6, thereby amplifying the pulsation until the same amplitude as the amplitude of the pulsation in the pipeline 1 and the antiphase thereof are attained. The amplified pulsating flow is introduced via the resonance section 7 into the pipeline 1, by which the pulsation in the pipeline 1 is decreased.
