An exhaust gas recirculation pump for an internal combustion engine that includes an electric motor assembly having an electric motor disposed within an electric motor housing. A roots device is coupled to the electric motor. The roots device includes a housing defining an internal volume. Rotors are disposed in the internal volume and connected to the electric motor. A bearing plate is attached to the housing wherein the bearing plate and an outer cover attached to the bearing plate defines an oil cavity. A transmission assembly is positioned on an opposing side of the housing relative to the electric motor and in the oil cavity.

Rear drive EGR pump

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.

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.

Supercharger

A coupling assembly arranged between an input shaft and a rotor shaft of a supercharger includes a first hub, a second hub, a first side coupling assembly, a second side coupling assembly, 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 first side coupling assembly can have a first side coupling body and a first side elastomeric insert. The second side coupling assembly can have a second side coupling body and a second side elastomeric insert. The central hub can define central hub bores therein. The plurality of coupler pins can be received in the central hub bores. The first and second side elastomeric inserts provide dampening between (i) the first side coupling body and the central hub and (ii) the second side coupling body and the central hub.

A thermal abatement system comprises an axial inlet, radial outlet supercharger. A main case comprises at least two rotor bores, an inlet plane and an outlet plane. The inlet plane is perpendicular to the outlet plane. An inlet wall comprises an inner surface. Two rotor mounting recesses are in the inner surface, and the inlet wall is parallel to the inlet plane. An outlet is in the outlet plane. An inlet is in the inlet plane. At least two rotors are configured to move air from the inlet to the outlet. The main case comprises at least two backflow ports. An intercooler is connected to receive air expelled from the supercharger, to cool the received air, and to expel the cooled air to the at least two back flow ports.

Thermal abatement systems

A fluid pressure actuator assembly (44) adapted for use with a valve member (42) is disclosed, the actuator being of the type comprising a housing assembly (50), and an axially moveable diaphragm assembly (56). A linkage member (48) is operably associated with said diaphragm assembly and extends axially through a linkage opening (70), and is connected to a valve member (42). A preload member (74) includes a generally annular preload portion (76) between a stop surface (55) and the diaphragm assembly (56), and in engagement with both. The preload portion (76) maintains the diaphragm assembly (56) in a position corresponding to a first position of said valve member (42), in opposition to the force of a biasing means (68). The preload member (74) includes a handle portion (78) extending axially through the linkage opening (70) whereby, after said linkage member (48) is connected to said valve member (42), the preload member (74) may be removed from the actuator through the linkage opening (70), by means of the handle portion (78).
