device introduces a new kind of hydraulic clutch. It's applied to
automatic gears changes as automatic clutch. Three pistons compose this
clutch and three valves piloted by eccentric force, and provide an
elastic and progressive coupling with no power loss. The
coupling is produced in function of the speeds of the conducting and led
shaft. This mechanism is simple, strong and reduced. With some
dimensions very tight is capable of transmitting a high torque in both
senses. Cylinders and hydraulic channels make a locked circuit
The engineers of an important world company car manufacturer have informed as follows:
"We appreciate the inventors
initiative in this direction. Introducing a new kind of hydraulic
coupling and solving torsional disturbances at the flywheel / clutch
interface are still one of the greatest challenges to improving
powertrain NHV behaviour.
