| 20080247894 | Vane Pump Using Line Pressure to Directly Regulate Displacement - A variable displacement vane pump includes at least two regulation chambers to provide a regulating force to the cam ring, to counter the force applied to the cam ring by a regulating spring, to reduce pulsation in the output working fluid from the pump. A first one of the chambers is part of the pump outlet and is in fluid communication with the outlet port of the pump via a passage which allows the pump to be fabricated from a diecast process oath like. A second regulation chamber is connected to the first chamber via an orifice which reduces the pressure of working fluid supplied from the first chamber to the second. The configuration and design of pumps in accordance with the present invention allows for flexible packaging for the pump, as the outlet need not overlie the pump outlet. Further, a pump with an inlet port with a relatively large initial cross-sectional flow area is taught to inhibit cavitation of the working fluid when the pump is operated at higher operating speeds. | 10-09-2008 |

| 20100216584 | Hybrid Transmissions with Planetary Gearsets - A transmission for use in a motor vehicle having an engine and a driveline is provided. The transmission includes an input shaft driven by the engine, an output shaft adapted for connection to the driveline, a mainshaft, a first planetary gearset, a motor/generator and a second planetary gearset. The first planetary gearset includes a first input member driven by the input shaft, a first output member driving the mainshaft and a first reaction member. The second planetary gearset includes a second input member, a second output member fixed to the output shaft and a ring gear operable to drive or be driven by the motor/generator. A rotor of the motor/generator circumscribes and is fixed to the ring gear. | 08-26-2010 |

| 20090090593 | Power Transmission Damper For a Torque Limiter - A damper assembly has a torque input member configured to be connected to engine crankshaft through a torque limit clutch. An output member has a hub configured to be mounted to a transmission input shaft. Damping springs operatively interconnects the input member and output member, enabling the input member and output member to rotate relative to each other at some angular displacements before the input torque from engine crankshaft is completely transmitted to transmission input shaft. The damping springs includes a series of long springs and a series of relatively short spring. The long springs compress before the short compress as the input member rotates relative to the output member. | 04-09-2009 |
