20110203550 | SUPERCHARGER WITH CONTINUOUSLY VARIABLE DRIVE SYSTEM - An engine system includes a throttle valve configured to variably open and close to selectively restrict a volume of air flow. The engine system also includes a supercharger comprising an air inlet, an air outlet, a rotatable drive shaft and rotors associated with the drive shaft, wherein the supercharger is sized to have a flow rate that substantially prevents backwards leaking of air flow. The engine system further includes a combustion engine comprising combustion chambers and an associated rotatable crank shaft and a continuously variable transmission (CVT) configured to variably transfer rotational energy between the drive shaft and the crank shaft. | 08-25-2011 |

20130160749 | SUPERCHARGER COUPLING - A rotational element coupling device in a supercharger includes a rotatable output shaft having tapered external splines and an output shaft axis of rotation. A coupling disk has a disk axis of rotation coaxial with the output shaft axis of rotation, a tapered internally splined bore coaxial with the disk axis of rotation to engage the tapered external splines, and a plurality of apertures defined in the coupling disk parallel to the disk axis of rotation. A plurality of pins each have a disk end and a timing gear end distal to the disk end. The plurality of pins matingly engages with the coupling disk at the disk end of the pins via the plurality of apertures. A timing gear is fixed to a supercharger rotor for rotation therewith. The timing gear has a plurality of apertures disposed therein to matingly engage with the timing gear end of the plurality of pins. | 06-27-2013 |
20140208745 | CONTROL STRATEGY FOR AN ENGINE - The present disclosure relates to a method of controlling an engine. The method includes manipulating a combustion air bypass valve between an open position and a closed position to create a negative pressure differential across a supercharger. The negative pressure differential is converted into a torque by the supercharger and transmitted from the supercharger back to the engine. | 07-31-2014 |
20140271136 | SUPERCHARGER - A supercharger includes a supercharger housing, a primary rotor having a primary rotor shaft fixed to rotate therewith. A ring gear with internal teeth is attached to a transmission housing portion of the supercharger housing. A sun gear is fixed to the primary rotor shaft. A planetary gear carrier has a plurality of planetary gear shafts. A plurality of planetary gears rotate about corresponding planetary gear shafts and are meshingly engaged with the sun gear and the ring gear and are substantially equally spaced about the sun gear. A rotatable input shaft is connectable to the planetary gear carrier. The input shaft is connectable to receive rotational motion and power from an engine. | 09-18-2014 |

20150118094 | POSITIVE DISPLACEMENT PUMP ASSEMBLY WITH MOVABLE END PLATE FOR ROTOR FACE CLEARANCE CONTROL - A positive displacement pump assembly includes a rotor housing defining a rotor cavity, and an end plate configured to at least partially close one end of the rotor cavity. Rotors are supported on and fixed to rotor shafts and extend through the rotor cavity. A first pair of bearings fixing the rotor shafts to the end plate. A second pair of bearings fixes the rotor shafts to the rotor housing, preventing relative axial movement between the rotor shafts and the rotor housing. The end plate is axially movable with the rotor shafts when the rotor shafts vary in axial length due to thermal fluctuations so that changes in an axial clearance at end faces of the rotors are reduced. | 04-30-2015 |

20140123939 | SUPERCHARGER WITH CONTINUOUSLY VARIABLE DRIVE SYSTEM - A combustion system comprises a supercharger with an operating range from an idled condition up to a maximum rotations per minute (RPM) of its drive shaft. An engine in the system has an engine operating range from an idled condition up to a maximum RPM of its crank shaft, the engine having at least one airflow demand for each RPM in the engine operating range for providing peak torque output. A continuously variable transmission (CVT) is connected to the drive shaft for transmitting a variable amount of rotational energy to operate the supercharger. The control system controls the transmitting of the CVT based on the at least one airflow demand for each RPM in the engine operating range such that the supercharger variably pumps air across the operating range as the engine operates across the engine operating range. | 05-08-2014 |
