Continuous torque transmission, particularly for motor vehicles, comprising a manual transmission (3), driven by a combustion engine (1) by a torque converter (2). This torque transmission comprises a double clutch (4) whose movement inputs are connected to the turbine (9) of said torque converter (2), and whose first movement output is connected to the input of the transmission (3), and whose second movement output is connected to any point of the kinematic chain of said torque transmission, while remaining downstream from the input shaft of the transmission.

Electrohydraulic translation apparatus, in particular permitting control

A first member of a magnetic housing has a core with a central passage and contains an electrical coil, and a second member of the housing has a ball cavity which receives and guides a magnetic ball. A central conduit and peripheral conduits enter the cavity of the second member. When the coil is activated, the magnetic field created thereby moves the ball into contact with the core to close the central passage in the first member, leaving the central and peripheral conduits in communication with each other. When the coil is deactivated, fluid pressure moves the ball to a position where it closes the central conduit so the central passage and the peripheral conduits will be in communication.

Three-way electrically-actuated hydraulic distributor

A transmission with epicyclic trains which includes four epicyclic trains permitting six forward speed ratios and one in reverse. With this transmission it is possible to obtain, by elimination of elements such as an annulus, brake bands or clutches, combinations of three, four and five forward speed ratios and one in reverse and is applicable to automobiles, buses and industrial vehicles.
