A blade family for torque converters with a first blade having a first shape and flow guiding surface and a second blade having a second shape and flow guiding surface. The first surface is different from the second surface and the first shape is the same as a portion of the second shape, or the second shape is the same as a portion of the second shape. In an example embodiment of the invention, at least one of the first or second blades includes holes or slots. In an example embodiment of the invention, the first blade includes more material than the second blade. The first and second blades may have respective mounting tabs, with the second blade having fewer mounting tabs than the first blade. Other example aspects of the present invention broadly comprise a torque converter with a plurality of first and/or second blades from the blade family.

Blade families for torque converters

A blade for a torque converter including a body having an outer edge, at least two shell tabs integral to the outer edge and extending therefrom and at least one flexible sealing flange adjacent to at least one of the at least two shell tabs, the at least one flexible sealing flange is integral to the outer edge and extending therefrom, wherein the outer edge is arranged to conform to an inner surface of a shell in a torque converter, the shell having at least two slots arranged therethrough, the at least one flexible sealing flange is arranged to conform to the inner surface of the shell to provide a fluid seal, the at least two shell tabs are disposed through the at least two slots and at least one of the at least two shell tabs is arranged to engage an outer surface of the shell.

Torque converter blade

A thrust washer for a torque converter, including a front surface and at least one first channel. The at least one channel is at least partially enclosed by the front surface and is in fluid communication with an inner circumference and an outer circumference for the thrust washer. The front surface is arranged to engage a cover for the torque converter. In some aspects, the at least one channel is fully enclosed by the front surface. The thrust washer also includes a back surface, oppositely disposed from the front surface. The at least one channel is at least partially enclosed by the back surface. In some aspects, the thrust washer includes a front piece and a back piece matingly engaged and configured to form the at least one channel. The front and back pieces are fixedly secured or removably secured.

Thrust washer with enclosed channels

More efficient, economic vehicular torque converters comprising novel integrated one-piece turbine/impeller blade-core assemblies with innovative fluid coupling means for greater torque capacities.

Integrated torque converters and assemblies

A torque converter in which the inner turbine output diameter or the inner pump input diameter is smaller than the inner stator passage diameter.

Torus shapes for torque converters

A torque converter in which a plurality of output openings of the pump form a cone-shape so that a plurality of input openings of the turbine are substantially parallel to the plurality of output openings of the pump.

A torque converter in which the output height of the output openings of the stator is higher than the input height of the input openings, producing a stator with a diffuser effect.

A torque converter with torus shape that is sheared such that imagined axial sections through the torus shape, starting from the inner stator passage diameter, are shifted increasingly axially in one direction as the effective radius increases.

A watercraft, equipped with a jet propulsion system with improved efficiency of operation is disclosed. Structures are disposed within a water passage of the jet propulsion system at a position upstream of the jet propulsion unit that modulate the amount of water that is allowed to pass through the water passage. The structures can be a flexible fluid filled bag, an adjustable ride plate, and an additional water passage. Each of the structures allow a greater amount of water into the water passage during acceleration than during constant speed travel of the watercraft.

Watercraft having a jet propulsion system with improved efficiency

Variable venturi for use in jet propulsion systems of watercraft include discharge openings with selectively variable discharge areas that enable a venturi controller to selectively maximize top speed, acceleration, and/or fuel efficiency. The variable venturi may include a plurality of circumferentially-spaced, squeezable, flexible sections that selectively move radially inwardly to alter the discharge area. Alternatively, the variable venturi may include a flexible venturi with a variably-shaped flexible discharge opening. Alternatively, the variable venturi may include a main rear discharge opening and a plurality of additional discharge openings with selectively openable valves, whereby selective opening of the valves effectively increases the discharge area. Alternatively, the variable venturi may have a movable end flap that selectively varies the discharge area.
