20150362052 | TRANSMISSION AND HYDRAULIC CONTROL SYSTEM - A hydraulic control system for an automatic transmission with a torque converter includes two regulator valves controlled by a single variable force solenoid (VFS). A bypass clutch regulator valve increases the pressure to a bypass clutch apply chamber as the VFS pressure increases. A converter charge regulator valve decreases the pressure in a converter charge circuit as the VFS pressure increases. The converter charge circuit is in series with a lubrication circuit. An orifice restricts the flow through these circuits such that they can be supplied from the line pressure circuit rather than a lower priority circuit. In one embodiment, an on/off solenoid opens a flow control valve to bypass the orifice when additional flow is required. In another embodiment, an electric pump supplements the flow in these circuits when required. This later embodiment includes a switch valve such that the electric pump also supports stop/start operation. | 12-17-2015 |

20090313983 | TURBO-TRANSMISSION - Improvements in a turbo transmission are provided for transferring power from a power source to a work unit. The transmission includes an input shaft coupled to a power source and to a pump that is configured to rotate with the input shaft. The pump transfers energy received from the power source into a fluid or gas. The transmission includes an output shaft and a multi-stage turbine in line. The first turbine is fixed to output shaft, and a plurality of additional turbines are fixed on either one-way overrunning clutches or multi-disc clutches and these clutches are fixed to the output shaft and after each turbine is a multi-valves that discharges the fluid or gas. After all of the multi-stage turbines a planetary gear set connects the turbo transmission to the vehicle or work unit. | 12-24-2009 |
20090313984 | HYDRAULIC HYBRID TURBO TRANSMISSION - Improvements in a transmission is provided for transferring power from a power source to a work unit. The pump transfers energy received from the power source into a fluid or gas. The first turbine is fixed to output shaft, and a plurality of additional turbines are fixed on either one-way overrunning clutches or multi-disc clutches and these clutches are fixed to the output shaft and after each turbine is a multi-valves that discharges the fluid or gas. After all of the multi-stage turbines a first planetary gear set connects the transmission to the vehicle or work unit. The second planetary gear set is located between the last turbine and the first planetary gear set. During braking the planetary gear set reverses turning direction of the turbines and convert the turbines into pumps where they will pump low pressure fluid to a high pressure accumulator. | 12-24-2009 |

20120073278 | STATOR CENTERING PLATE - A stator assembly for a torque converter includes first and second blade plates, a one-way clutch assembly disposed axially between the blade plates and a centering plate. The one-way clutch assembly has an inner race with an outer circumferential surface, an outer race with an outer circumferential surface, and a plurality of blocking elements disposed radially between the inner race and the outer race. The centering plate includes a ring portion grippingly engaged with the outer race outer circumferential surface and an annular portion with an inner circumferential surface arranged to radially position the inner race outer circumferential surface. In an example embodiment, at least one of the blade plates is made by stamping. | 03-29-2012 |
20120186242 | STARTING DEVICE HAVING A THROTTLE PLATE - A starting device for a motor vehicle includes a pump connected to a prime mover and a turbine connected to a turbine shaft. The pump and turbine are hydrodynamically connected. A stator assembly is disposed between the pump and the turbine. The stator assembly houses a slidable throttle plate. In a first position, the throttle plate partially blocks a return fluid flow from the stator assembly, thereby effectively reducing the capacity of the starting device. In a second position, the throttle plate does not reduce the capacity of the starting device. The throttle plate position is a function of a balance of forces acting on the throttle plate by a biasing member and a flow of hydraulic fluid contacting the throttle plate. | 07-26-2012 |

The first stator impeller is coupled to a fixed shaft via the first and second one-way clutches, and the second stator impeller is coupled to the fixed shaft only via the second one-way clutch. | 07-11-2013 |
20150128582 | ONE-WAY PLATE AND STATOR SUPPORT STRUCTURE FOR TORQUE CONVERTER USING SAME - A stator support structure supports a stator of a torque converter on a stationary shaft, and includes an inner race and an annular one-way plate. The inner race is coupled to the stationary shaft to be non-rotatable relative thereto, and has a plurality of protrusions on the outer peripheral surface thereof. The annular one-way plate is mounted to the inner peripheral surface of the stator to be non-rotatable relative thereto, and has a plurality of pawls. The pawls are configured to prevent relative rotation between the stator and the inner race by making contact with first end surfaces formed as one rotation-directional end surfaces of the plural protrusions when the stator is rotated in a first direction. The pawls are configured to allow relative rotation between the stator and the inner race by elastically deforming in a radial direction to climb over the protrusions when the stator is rotated in a second direction. | 05-14-2015 |

A first curved surface and a second curved surface are formed between the leading edge and the trailing edge of the blade. A camber line is defined through the leading edge and the trailing edge. The camber line is oriented at a negative angle relative to the flow direction. | 12-17-2015 |
