Abstract:
An automotive vapor pump for pumping a pump gas having a fuel vapor. The automotive vapor pump includes a pump inlet opening, a pump outlet opening, an outlet volute, a pump outlet duct which is substantially tangential and which fluidically connects the outlet volute with the pump outlet opening, a centrifugal pumping wheel which pumps the pump gas from the pump inlet opening into the outlet volute and subsequently into the pump outlet duct, an electric motor which drives a pumping wheel, the electric motor including a static motor coil, a magnetic rotor body, and a motor driving electronics which drives the static motor coil, an electric connector plug which electrically connects the motor driving electronics with an external control unit, and an integrated pressure sensor which detects a fluidic pressure in the outlet volute or in the pump outlet duct.
