摘要： This hydrodynamic torque converter for the automatic transmission of motor vehicles which provide several gear ratios comprises means for bridging the input and output shafts of the converter. The hydraulic fluid supplied through the hollow transmission shaft penetrates into the converter inner space via a gaged orifice; the outlet of the control chamber of the converter is closed by a solenoid valve in one position thereof; the pressure in the converter inner space is the same as in the control chamber, and spring means are provided for urging the control piston to its release position when the assembly operates as a torque converter. In the other valve position the pressure prevailing in the converter inner space having its outlet closed is applied to the control piston against the force of the spring means. The pressure in the control chamber is low and thus the friction lining carried by the control piston produces the desired bridging action.

摘要： The control device comprises a moving slide 25 acted on by a return spring 27 and capable of uncovering an orifice 31 allowing hydraulic fluid to be fed to a release chamber 32 moving the control piston 17 removing the "bridging" between the input impeller 2 and the output turbine 10 of the converter 1. The "bridging" is actuated by an electrohydraulic transducer 43 controlled by an electronic device 49 in accordance with the input and output speeds sensed by sensors 46 and 48."Bridging" of the converter 1 is thus achieved for all the transmission ratios as well as "debridging" on each change from one ratio to another.
