Abstract: An EGR pump system includes an EGR pump assembly including an electric motor assembly coupled to a transmission assembly. A roots device is coupled to the electric motor through the transmission assembly. The roots device includes a housing defining an internal volume and rotors are disposed in the internal volume and connected to the transmission assembly. An EGR locking mechanism is attached to the EGR pump assembly. The EGR locking mechanism is selectively connected to the transmission assembly locking the transmission assembly and preventing rotation of the rotors.

Abstract: A coupling assembly arranged between an input shaft and a rotor shaft of a supercharger includes a first hub, a second hub, a central hub, and a plurality of coupler pins. The first hub can be mounted with the input shaft. The second hub can be mounted with the rotor shaft. The central hub can be disposed in between the first and second hubs. The central hub can have an elastomeric body that defines a series of passages therein. The passages can taper inwardly throughout and provide incremental dampening against the first and second plurality of pins. The plurality of coupler pins can be received in the central hub bores. The first and second plurality of pins can be received by the passages in the elastomeric body.
