Provided is a blade assembling method for a converter, wherein a blade 20 held by blade holding means (adsorption part 152) is further relatively moved with respect to a shell 10, whereby, while remaining claws 21B and 21C of the blade 20 are pressed against the upper surface of the shell 10 in an obliquely forward and downward direction by the holding force of the blade holding means (adsorption part 152), the claws 21B and 21C are slid toward grooves 11B and 11C from the near side of the corresponding grooves 11B and 11C and inserted so as to fall in the grooves 11B and 11C to thereby insert all the claws 21A to 21C into all the corresponding grooves 11A to 11C, respectively.

A torque converter, including: a cover to receive torque; an impeller including an impeller shell non-rotatably connected to the cover and an impeller blade; a turbine including a turbine shell and a turbine blade; a first vibration damper including a drive plate to receive torque from the cover, a first cover plate including first and second portions, a first spring directly engaged with the drive plate and the first portion of the first cover plate, and a second cover plate non-rotatably connected to the first cover plate, surrounding a portion of the first spring in a direction orthogonal to a longitudinal axis for the first spring, and including an opening; and a second vibration damper including a cover plate non-rotatably connected to the turbine shell, and a second spring directly engaged with the cover plate for the second vibration damper and with the second portion of the first cover plate.

A coupling has a housing and a returning unit and a turbo fan coaxially disposed within the housing. The housing has a first shell and a second shell coaxially connected to the first shell. The first shell has multiple driving ribs therein. Each driving rib has a guiding plate, a driving plate connected to the guiding plate, and an included angle defined between the driving plate and the guiding plate of the driving rib. The second shell has multiple divergent ribs therein. Fluid introduced into the housing is guided to the multiple driving ribs of the first shell via the divergent ribs of the second shell. The fluid pushes the driving plate of each driving rib and facilitates the housing to spin and drive a driven device. Therefore, the coupling of the present invention can save energy consumption for driving a driven device.

A torque converter, including an impeller including an impeller shell with an inner surface, an outer surface facing opposite the inner surface, a first radial portion substantially orthogonal to an axis of rotation for the torque converter, and an axial portion substantially parallel to the axis, extending from the radial portion, forming a radially outmost portion of the impeller shell, and having a first thickness. The shell includes a curved portion including a first protrusion, second and third protrusions radially inward of the first protrusion, a first portion between the radial portion and the first protrusion, and a junction portion connecting the radial portion and the first portion and having a second thickness at least 50 percent greater than the first thickness.

A torque converter includes a housing, and an impeller shell disposed within the housing. The impeller shell has a back wall, and a plurality of fins radially arranged and extending outwardly from the back wall. The torque converter further includes a backing hub rigidly coupled to the back wall of the impeller shell. The backing hub has a barrier element extending therefrom. A free end of the barrier element is disposed proximal to the housing to restrict a flow of fluid therebetween.
