Abstract
Synchronized Induction & Discharge Flows (SIDF) for a rotary lobe blower (pump) or vacuum pump reduce flow pulsations, noise, vibration, harshness (NVH) and improve blower efficiency. Generally, a rotary lobe blower (pump) or vacuum pump with a SIDF has a pair of mechanically synchronized multi-lobe rotors with the same number of lobes housed in a well of a casing wall with an off-center suction port and discharge port. The fluid being trapped by adjacent lobes of each of the rotors and the walls along two flanks of the walls of the well are synchronized wherein the suction port and the discharge port have each an axis that are parallel with each other; the suction port axis and the discharge port axis being offset with each other; wherein the offset provides simultaneous fluid inducting for the two flanks at the suction port and simultaneous fluid back filling and discharging for the two flanks at the discharge port respectively.
