1. A rotary blower with a Synchronized Induction & Discharge Flows (SIDF) apparatus, comprising:
a. a casing having a suction port, a discharge port and walls defining a well therein;
b. two multi-lobe rotors with the same number of lobes located in said well interconnected through a set of timing gears to counter-rotate in synchronization such that fluid is passing through the said suction port to the said discharge port;
c. the said fluid being trapped by adjacent said lobes of each of said rotors and the said walls along two flanks of the said walls of the said well are synchronized wherein the said suction port and the said discharge port have each an axis that are parallel with each other, the said suction port axis and the said discharge port axis being offset with each other; said offset provides simultaneous fluid inducting for said two flanks at said suction port and simultaneous fluid back filling and discharging for said two flanks at said discharge port respectively;
d. whereby said rotary blower is achieving high pulsation and NVH reduction at source and improving blower efficiency while being kept light in mass, compact in size.
