Appl. No.:

10/411190

Inventors:

Patrice Dusablon - Palm Bay FL, US
Gilles Pesant - Palm Bay FL, US
Bhaskar Marathe - Wooster OH, US

Assignee:

Bombardier Recreational Products Inc. - Valcourt

International Classification:

B63H021/22

US Classification:

440 1, 440 38, 440 47

Abstract:

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.

International Classification:

F16C 17/04

US Classification:

384420, 384303, 384368

Abstract:

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.
