Patent number: 9751411Abstract: A supercharger assembly includes a supercharger in series with an engine that has a crankshaft and has an air intake manifold defining a plenum through which air flow is provided to the engine. A supercharger is upstream of the plenum in air flow to the engine and has a first rotor rotatable with a first shaft and a second rotor rotatable with a second shaft. The supercharger assembly also includes an electric motor-generator that is selectively alternately operable as a motor and as a generator, and a planetary gearing arrangement having a first member operatively connected to the electric motor-generator, a second member connectable to be rotated by the engine crankshaft, and a third member operatively connected for rotation with the first shaft. The supercharger assembly has only two selectively engageable torque-transmitting mechanisms and a control system configured to control the electric motor-generator and the torque-transmitting mechanisms.Type: GrantFiled: March 13, 2013Date of Patent: September 5, 2017Assignee: Eaton CorporationInventors: Robert P.

Patent number: 9074524Abstract: An air supply system is provided that uses two sets of rotors on a common set of shafts to boost air in two stages. The air supply system includes a housing and a first and a second rotatable shaft at least partially within the housing. A first and a second pair of rotors are included. Each pair of rotors has a first rotor supported for rotation on the first shaft and a second rotor supported for rotation on the second shaft. The housing has an inlet at the first pair of rotors, an outlet at the second pair of rotors, and an internal chamber between the first and the second pairs of rotors. Air flow from the inlet to the outlet thereby has a first pressure boost from the inlet to the internal chamber and a second pressure boost from the inlet chamber to the outlet.Type: GrantFiled: December 9, 2011Date of Patent: July 7, 2015Assignee: Eaton CorporationInventors: William N.

Patent number: 5832741Abstract: A bi-directional filter/drier having a flat header welded to a casing with a desiccant canister disposed in the casing. The header has a dedicated low side pressure inlet port formed in the flat which communicates through a pair of oppositely disposed check valves in a cross passage with two separate bi-directional inlet/outlet ports into which low side pressure flow is permitted to by-pass the desiccant to the bi-directional ports. Individual passages, each with a stiffer check valve are provided between the bi-directional ports for permitting high side pressure to flow in either port into the desiccant. A stand pip through the desiccant is connected to an interior port in the header and communicates with a dedicated outlet port in header exterior.Type: GrantFiled: October 18, 1996Date of Patent: November 10, 1998Assignee: Eaton CorporationInventors: Wayne K.
